Summary of Significant Accounting Policies	12 Months Ended
	Sep. 30, 2013
Summary of Significant Account Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Nature of Business
	Red Trail Energy, LLC, a North Dakota limited liability company (the “Company”), owns and operates a 50 million gallon annual name-plate production ethanol plant near Richardton, North Dakota (the “Plant”). The plant commenced production on January 1, 2007. Fuel grade ethanol, distillers grains and corn oil are the Company's primary products. All products are marketed and sold primarily within the continental United States.
	Accounting Estimates
	Management uses estimates and assumptions in preparing these financial statements in accordance with generally accepted accounting principles. Those estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported revenues and expenses. Significant items subject to such estimates and assumptions include the useful lives of property, plant and equipment, valuation of derivatives, inventory, and purchase commitments; the analysis of long-lived assets impairment and other contingencies. Actual results could differ from those estimates.
	Cash and Equivalents
	The Company considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. The carrying value of cash and equivalents approximates fair value.
	Accounts Receivable and Concentration of Credit Risk
	The Company generates accounts receivable from sales of ethanol, distillers grains and corn oil. The Company has entered into agreements with RPMG, Inc. (“RPMG”) and CHS, Inc. (“CHS”) for the marketing and distribution of the Company's ethanol, corn oil and dried distiller's grains, respectively. Under the terms of the marketing agreements, both RPMG and CHS bear the risk of loss of nonpayment by their customers. The Company markets its modified distiller's grains internally. Following the end of the Company's 2013 fiscal year, RPMG markets the Company's dried distillers grains.
	For sales of modified distiller's grains, credit is extended based on evaluation of a customer's financial condition and collateral is not required. Accounts receivable are due 30 days from the invoice date. Accounts outstanding longer than the contractual payment terms are considered past due. Internal follow up procedures are followed accordingly. Interest is charged on past due accounts.
	All receivables are stated at amounts due from customers net of any allowance for doubtful accounts. The Company determines its allowance by considering a number of factors, including the length of time trade accounts receivable are past due, the Company's previous loss history, the customer's perceived current ability to pay its obligation to the Company, and the condition of the general economy and the industry as a whole. The Company writes off accounts receivable when they become uncollectible, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts. The Company has an allowance for doubtful accounts of approximately $106,800 and $1,500 at September 30, 2013 and 2012, respectively.
	Inventory
	Corn is the primary raw material and, along with other raw materials and supplies, is stated at the lower of cost or market on a first-in, first-out (FIFO) basis.  Work in process and finished goods, which consists of ethanol, distillers grains and corn oil produced, is stated at the lower of average cost or market.  Spare parts inventory is valued at lower of cost or market on a FIFO basis.
	Patronage Equity
	The Company receives, from certain vendors organized as cooperatives, patronage dividends, which are based on several criteria, including the vendor's overall profitability and the Company's purchases from the vendor. Patronage equity typically represents the Company's share of the vendor's undistributed current earnings which will be paid in either cash or equity interests to the Company at a future date. Investments in cooperatives are stated at cost, plus unredeemed patronage refunds received in the form of capital stock and are included in Other Assets on the Company's balance sheet.
	Derivative Instruments
	The Company enters into derivative transactions to hedge its exposure to commodity and interest rate price fluctuations. The Company is required to record these derivatives in the balance sheet at fair value.
	In order for a derivative to qualify as a hedge, specific criteria must be met and appropriate documentation maintained. Gains and losses from derivatives that do not qualify as hedges, or are undesignated, must be recognized immediately in earnings. If the derivative does qualify as a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will be either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings or recognized in other comprehensive income until the hedged item is recognized in earnings. Changes in the fair value of undesignated derivatives related to corn are recorded in costs of goods sold within the statements of operations. Changes in the fair value of undesignated derivatives related to ethanol are recorded in revenue within the statements of operations. Changes of fair value of undesignated interest rate swaps are recorded in interest expense within the statement of operations.
	Additionally the Company is required to evaluate its contracts to determine whether the contracts are derivatives. Certain contracts that literally meet the definition of a derivative may be exempted as “normal purchases or normal sales.” Normal purchases and normal sales are contracts that provide for the purchase or sale of something other than a financial instrument or derivative instrument that will be delivered in quantities expected to be used or sold over a reasonable period in the normal course of business. Certain corn, ethanol and distiller's grain contracts that meet the requirement of normal purchases or sales are documented as normal and exempted from the accounting and reporting requirements, and therefore, are not marked to market in our financial statements.
	Firm Purchase Commitments
	The Company typically enters into fixed price contracts to purchase corn to ensure an adequate supply of corn to operate its plant. The Company will generally seek to use exchange traded futures, options or swaps as an offsetting economic hedge position. The Company closely monitors the number of bushels hedged using this strategy to avoid an unacceptable level of margin exposure. Contract prices are analyzed by management at each period end and, if necessary, valued at the lower of cost or market in the balance sheets.
	Revenue Recognition
	The Company generally sells ethanol and related products pursuant to marketing agreements. Revenues are recognized when the customer has taken title, which occurs when the product is shipped, has assumed the risks and rewards of ownership, prices are fixed or determinable and collectability is reasonably assured.
	Revenues are shown net of any fees incurred under the terms of the Company's agreements for the marketing and sale of ethanol and related products.
	Long-lived Assets
	Property, plant, and equipment are stated at cost. Depreciation is provided over estimated useful lives by use of the straight line method. Maintenance and repairs are expensed as incurred. Major improvements and betterments are capitalized. The present values of capital lease obligations are classified as long-term debt and the related assets are included in property, plant and equipment. Amortization of equipment under capital leases is included in depreciation expense.
	Depreciation is computed using the straight-line method over the following estimated useful lives:
		Minimum Years	Maximum Years
	Land improvements	15	30
	Buildings	10	40
	Plant and equipment	7	40
	Long-lived assets, such as property, plant, and equipment, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by an asset to the carrying value of the asset. If the carrying value of the long-lived asset is not recoverable on an undiscounted cash flow basis, impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including, but not limited to, discounted cash flow models, quoted market values and third-party independent appraisals.
	Fair Value of Financial Instruments
	The Company has adopted guidance for accounting for fair value measurements of financial assets and financial liabilities and for fair value measurements of nonfinancial items that are recognized or disclosed at fair value in the financial statements on a recurring basis. The Company has adopted guidance for fair value measurement related to nonfinancial items that are recognized and disclosed at fair value in the financial statements on a nonrecurring basis. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements).
	The three levels of the fair value hierarchy are as follows:
	·                  Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
	·                  Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.
	·                  Level 3 inputs are unobservable inputs for the asset or liability.
	The level in the fair value hierarchy within which a fair measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety.
	Except for those assets and liabilities which are required by authoritative accounting guidance to be recorded at fair value in our balance sheets, the Company has elected not to record any other assets or liabilities at fair value. No events occurred during the fiscal years ended September 30, 2013 and 2012 that required adjustment to the recognized balances of assets or liabilities, which are recorded at fair value on a nonrecurring basis.
	Grants
	The Company recognizes grant proceeds as other income for reimbursement of expenses incurred upon complying with the conditions of the grant. For reimbursements of capital expenditures, the grants are recognized as a reduction of the basis of the asset upon complying with the conditions of the grant. In addition, the Company considers production incentive payments received to be economic grants and includes such amounts in other income when received, as this represents the point at which they are fixed and determinable.
	Shipping and Handling
	The cost of shipping products to customers is included in cost of goods sold.  Amounts billed to a customer in a sale transaction related to shipping and handling is classified as revenue.
	Income Taxes
	The Company is treated as a partnership for federal and state income tax purposes and generally does not incur income taxes. Instead, its earnings and losses are included in the income tax returns of the members. Therefore, no provision or liability for federal or state income taxes has been included in these financial statements.
	Differences between financial statement basis of assets and tax basis of assets is primarily related to depreciation, interest rate swaps, derivatives, inventory, compensation and capitalization and amortization of organization and start-up costs for tax purposes, whereas these costs are expensed for financial statement purposes.
	The Company has evaluated whether it has any significant tax uncertainties that would require recognition or disclosure. Primarily due to its partnership tax status, the Company does not have any significant tax uncertainties that would require recognition or disclosure.
	The Company files income tax returns in the U.S. federal jurisdiction and various states. The Company is no longer subject to income tax examinations by U.S. federal tax authorities or the states where the Company files tax returns for tax years ended on or prior to December 31, 2009.
	Net Income (Loss) Per Unit
	Net income (loss) per unit is calculated on a basic and fully diluted basis using the weighted average units outstanding during the period.
	Environmental Liabilities
	The Company's operations are subject to environmental laws and regulations adopted by various governmental entities in the jurisdiction in which it operates. These laws require the Company to investigate and remediate the effects of the release or disposal of materials at its location. Accordingly, the Company has adopted policies, practices and procedures in the areas of pollution control, occupational health and the production, handling, storage and use of hazardous materials to prevent material, environmental or other damage, and to limit the financial liability which could result from such events. Environmental liabilities, if any, are recorded when the liability is probable and the costs can reasonably be estimated. The Company is not aware of any environmental liabilities identified as of September 30, 2013.

	CONCENTRATIONS
	Coal
	Coal is an important input to our manufacturing process. During the fiscal year ended September 30, 2013, we used approximately 83,000 tons of coal. We have entered into a one year agreement with Westmoreland Coal Sales Company (“Westmoreland”) to supply PRB coal through December 2013 and the Company does not anticipate any problems negotiating a renewal of this contract. The Company's intentions are to renew this supply agreement with its current coal supplier. We believe there is sufficient supply of coal from the PRB coal regions in Wyoming and Montana to meet our demand for PRB coal. In addition to coal, we could use natural gas as a fuel source if our coal supply is significantly interrupted. Because we are already operating on coal, we do not expect to need natural gas unless coal interruptions impact our operations.
	Sales
	We are substantially dependent upon RPMG for the purchase, marketing and distribution of our ethanol and corn oil. RPMG purchases 100% of the ethanol and corn oil produced at our plant, all of which is marketed and distributed to its customers. Therefore, we are highly dependent on RPMG for the successful marketing of our ethanol and corn oil. In the event that our relationship with RPMG is interrupted or terminated for any reason, we believe that we could locate another entity to market the ethanol and corn oil. However, any interruption or termination of this relationship could temporarily disrupt the sale and production of ethanol and corn oil and adversely affect our business and operations and potentially result in a higher cost to the Company. Amounts due from RPMG represent approximately 80% and 69% of the Company's outstanding trade receivables balance at September 30, 2013 and 2012, respectively. Approximately 79%, 79%, and 84% of revenues are comprised of sales to RPMG for the year ended September 30, 2013, the year ended September 30, 2012 and the nine months ended September 30, 2011, respectively.
	During our 2013 fiscal year, we were substantially dependent on CHS for the purchase, marketing and distribution of our DDGS. CHS purchased 100% of the DDGS produced at the plant during our 2013 fiscal year, all of which are marketed and distributed to its customers. Effective as of October 1, 2013, RPMG will purchase 100% of the DDGS produced at the plant to market and distribute to its customers. Therefore, we are highly dependent on RPMG for the successful marketing of our DDGS. In the event that our relationship with RPMG is interrupted or terminated for any reason, we believe that another company could be engaged to market the DDGS. However, any interruption or termination of this relationship could temporarily disrupt the sale and production of DDGS and adversely affect our business and operations.

	DERIVATIVE INSTRUMENTS
	Commodity Contracts
	As part of its hedging strategy, the Company may enter into ethanol, soybean oil, and corn commodity-based derivatives in order to protect cash flows from fluctuations caused by volatility in commodity prices in order to protect gross profit margins from potentially adverse effects of market and price volatility on ethanol sales, corn oil sales, and corn purchase commitments where the prices are set at a future date. These derivatives are not designated as effective hedges for accounting purposes. For derivative instruments that are not accounted for as hedges, or for the ineffective portions of qualifying hedges, the change in fair value is recorded through earnings in the period of change. Ethanol derivative fair market value gains or losses are included in the results of operations and are classified as revenue and corn derivative changes in fair market value are included in cost of goods sold.

	Inventory is valued at lower of cost or market. Inventory values as of September 30, 2013 and 2012 were as follows:
	As of	30-Sep-13			30-Sep-12
	Raw materials, including corn, chemicals and supplies	$	7,510,059		$	7,455,660

	Spare parts	1,672,139			1,260,105
	Total inventory	$	12,189,693		$	13,650,907
	Lower of cost or market adjustments for the year ended September 30, 2013, 2012, and the nine months ended September 30, 2011 were as follows:
			For the year ended September 30, 2013			For the year ended September 30, 2012		For the nine months ended September 30, 2011
	Loss on firm purchase commitments		$	1,091,000		$	132,000	$	444,000
	Loss on lower of cost or market adjustment for inventory on hand		665,300			327,000		450,000
	Total loss on lower of cost or market adjustments		$	1,756,300		$	459,000	$	894,000
	The Company has entered into forward corn purchase contracts under which it is required to take delivery at the contract price. At the time the contracts were created, the price of the contract price approximated market price. Subsequent changes in market conditions could cause the contract prices to become higher or lower than market prices.
	As of September 30, 2013, the average price of corn purchased under certain fixed price contracts, that had not yet been delivered, was higher than approximated market price. Based on this information, the Company accrued an estimated loss on firm purchase commitments of $1,091,000 for the twelve months ended September 30, 2013. Losses of $132,000 and $444,000 were accrued for the year ended September 30, 2012 and nine month period ended September 30, 2011, respectively. The loss is recorded in “Loss on firm purchase commitments” on the statements of operations. The amount of the loss was determined by applying a methodology similar to that used in the impairment valuation with respect to inventory. Given the uncertainty of future ethanol prices, this loss may or may not be recovered, and further losses on the outstanding purchase commitments could be recorded in future periods.
	The Company recorded inventory valuation impairments of $665,300, $327,000 and $450,000 for the year ended September 30, 2013, the year ended September 30, 2012 and the nine month period ended September 30, 2011, respectively. The impairments, as applicable, were attributable primarily to decreases in market prices of ethanol. The inventory valuation impairment was recorded in “Lower of cost or market adjustment” on the statements of operations.

	On May 15, 2013, the Company executed amended and restated loan agreements with its primary lender, First National Bank of Omaha ("FNBO"). The purposes of the amended and restated loan agreements were to extend the maturity date of the Company's current credit facilities, to adjust the interest rates payable pursuant to the Company's various credit facilities with FNBO and to change the amounts available under the Company's revolving loans. The loan agreements all provide for a variable interest rate as of September 30, 2013 with the term loan interest rate at 3.77% and long-term revolver interest rate at 3.77% and the operating line-of-credit interest rate at 3.68%. Repayment terms on the $20,000,000 term loan are $500,000 per quarter and $125,000 per quarter reduction in the total amount available from the initial $5,000,000 long-term revolver. Both of these loans mature on April 16, 2017. The $10,000,000 operating line-of-credit has a maturity date of April 15, 2014. At September 30, 2013, the Company had $3,708,000 drawn on the long-term revolver and $0 drawn on the operating line of credit.

	GRANTS
	In 2006, the Company entered into a contract with the State of North Dakota through the Industrial Commission for a lignite coal grant not to exceed $350,000. The Company received $275,000 from this grant during 2006 with this amount currently shown in the liability section of the Company's Balance Sheet as Contracts Payable. Because the Company has not met the minimum lignite usage requirements specified in the grant for any year in which the plant has operated, it expects to have to repay the grant and is awaiting instructions from the Industrial Commission as to the terms of the repayment schedule. This repayment could begin in fiscal 2014.
	The Company has entered into an agreement with Job Service North Dakota for a new jobs training program. This program provides incentives to businesses that are creating new employment opportunities through business expansion and relocation to the state. The program provides no-cost funding to help offset the cost of training. The Company is eligible to receive up to approximately $270,000 over ten years. The Company received and earned approximately $39,000, $41,000 and $29,000 for the years ended September 30, 2013, 2012, and the nine month period ended September 30, 2011, respectively.

Uncertainties Impacting the Ethanol Industry and Our Future Operations	'
	UNCERTAINTIES IMPACTING THE ETHANOL INDUSTRY AND OUR FUTURE OPERATIONS
	The Company has certain risks and uncertainties that it experiences during volatile market conditions, which can have a severe impact on operations. The Company's revenues are derived from the sale and distribution of ethanol and distillers grains to customers primarily located in the U.S. Corn for the production process is supplied to the plant primarily from local agricultural producers and from purchases on the open market. The Company's operating and financial performance is largely driven by prices at which the Company sells ethanol and distillers grains and by the cost at which it is able to purchase corn for operations. The price of ethanol is influenced by factors such as prices, supply and demand, weather, government policies and programs, and unleaded gasoline and the petroleum markets, although since 2005 the prices of ethanol and gasoline began a divergence with ethanol selling for less than gasoline at the wholesale level. Excess ethanol supply in the market, in particular, puts downward pressure on the price of ethanol. The Company's largest cost of production is corn. The cost of corn is generally impacted by factors such as supply and demand, weather, government policies and programs. The Company's risk management program is used to protect against the price volatility of these commodities.

Accounting Estimates	'
	Accounting Estimates
	Management uses estimates and assumptions in preparing these financial statements in accordance with generally accepted accounting principles. Those estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported revenues and expenses. Significant items subject to such estimates and assumptions include the useful lives of property, plant and equipment, valuation of derivatives, inventory, and purchase commitments; the analysis of long-lived assets impairment and other contingencies. Actual results could differ from those estimates.

	Cash and Equivalents
	The Company considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. The carrying value of cash and equivalents approximates fair value.
Accounts Receivable and Concentration of Credit Risk	'
	Accounts Receivable and Concentration of Credit Risk
	The Company generates accounts receivable from sales of ethanol, distillers grains and corn oil. The Company has entered into agreements with RPMG, Inc. (“RPMG”) and CHS, Inc. (“CHS”) for the marketing and distribution of the Company's ethanol, corn oil and dried distiller's grains, respectively. Under the terms of the marketing agreements, both RPMG and CHS bear the risk of loss of nonpayment by their customers. The Company markets its modified distiller's grains internally. Following the end of the Company's 2013 fiscal year, RPMG markets the Company's dried distillers grains.
	For sales of modified distiller's grains, credit is extended based on evaluation of a customer's financial condition and collateral is not required. Accounts receivable are due 30 days from the invoice date. Accounts outstanding longer than the contractual payment terms are considered past due. Internal follow up procedures are followed accordingly. Interest is charged on past due accounts.
	All receivables are stated at amounts due from customers net of any allowance for doubtful accounts. The Company determines its allowance by considering a number of factors, including the length of time trade accounts receivable are past due, the Company's previous loss history, the customer's perceived current ability to pay its obligation to the Company, and the condition of the general economy and the industry as a whole. The Company writes off accounts receivable when they become uncollectible, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts. The Company has an allowance for doubtful accounts of approximately $106,800 and $1,500 at September 30, 2013 and 2012, respectively.
Inventory	'
	Inventory
	Corn is the primary raw material and, along with other raw materials and supplies, is stated at the lower of cost or market on a first-in, first-out (FIFO) basis.  Work in process and finished goods, which consists of ethanol, distillers grains and corn oil produced, is stated at the lower of average cost or market.  Spare parts inventory is valued at lower of cost or market on a FIFO basis.
Patronage Equity	'
	Patronage Equity
	The Company receives, from certain vendors organized as cooperatives, patronage dividends, which are based on several criteria, including the vendor's overall profitability and the Company's purchases from the vendor. Patronage equity typically represents the Company's share of the vendor's undistributed current earnings which will be paid in either cash or equity interests to the Company at a future date. Investments in cooperatives are stated at cost, plus unredeemed patronage refunds received in the form of capital stock and are included in Other Assets on the Company's balance sheet.
Derivatives Instruments	'
	Derivative Instruments
	The Company enters into derivative transactions to hedge its exposure to commodity and interest rate price fluctuations. The Company is required to record these derivatives in the balance sheet at fair value.
	In order for a derivative to qualify as a hedge, specific criteria must be met and appropriate documentation maintained. Gains and losses from derivatives that do not qualify as hedges, or are undesignated, must be recognized immediately in earnings. If the derivative does qualify as a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will be either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings or recognized in other comprehensive income until the hedged item is recognized in earnings. Changes in the fair value of undesignated derivatives related to corn are recorded in costs of goods sold within the statements of operations. Changes in the fair value of undesignated derivatives related to ethanol are recorded in revenue within the statements of operations. Changes of fair value of undesignated interest rate swaps are recorded in interest expense within the statement of operations.
	Additionally the Company is required to evaluate its contracts to determine whether the contracts are derivatives. Certain contracts that literally meet the definition of a derivative may be exempted as “normal purchases or normal sales.” Normal purchases and normal sales are contracts that provide for the purchase or sale of something other than a financial instrument or derivative instrument that will be delivered in quantities expected to be used or sold over a reasonable period in the normal course of business. Certain corn, ethanol and distiller's grain contracts that meet the requirement of normal purchases or sales are documented as normal and exempted from the accounting and reporting requirements, and therefore, are not marked to market in our financial statements.
Firm Purchase Commitments	'
	Firm Purchase Commitments
	The Company typically enters into fixed price contracts to purchase corn to ensure an adequate supply of corn to operate its plant. The Company will generally seek to use exchange traded futures, options or swaps as an offsetting economic hedge position. The Company closely monitors the number of bushels hedged using this strategy to avoid an unacceptable level of margin exposure. Contract prices are analyzed by management at each period end and, if necessary, valued at the lower of cost or market in the balance sheets.
Revenue Recognition	'
	Revenue Recognition
	The Company generally sells ethanol and related products pursuant to marketing agreements. Revenues are recognized when the customer has taken title, which occurs when the product is shipped, has assumed the risks and rewards of ownership, prices are fixed or determinable and collectability is reasonably assured.
	Revenues are shown net of any fees incurred under the terms of the Company's agreements for the marketing and sale of ethanol and related products.
Long-Lived Assets	'
	Long-lived Assets
	Property, plant, and equipment are stated at cost. Depreciation is provided over estimated useful lives by use of the straight line method. Maintenance and repairs are expensed as incurred. Major improvements and betterments are capitalized. The present values of capital lease obligations are classified as long-term debt and the related assets are included in property, plant and equipment. Amortization of equipment under capital leases is included in depreciation expense.
	Depreciation is computed using the straight-line method over the following estimated useful lives:
		Minimum Years	Maximum Years
	Land improvements	15	30
	Buildings	10	40
	Plant and equipment	7	40
	Long-lived assets, such as property, plant, and equipment, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by an asset to the carrying value of the asset. If the carrying value of the long-lived asset is not recoverable on an undiscounted cash flow basis, impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including, but not limited to, discounted cash flow models, quoted market values and third-party independent appraisals.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The Company has adopted guidance for accounting for fair value measurements of financial assets and financial liabilities and for fair value measurements of nonfinancial items that are recognized or disclosed at fair value in the financial statements on a recurring basis. The Company has adopted guidance for fair value measurement related to nonfinancial items that are recognized and disclosed at fair value in the financial statements on a nonrecurring basis. The guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements).
	The three levels of the fair value hierarchy are as follows:
	·                  Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
	·                  Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.
	·                  Level 3 inputs are unobservable inputs for the asset or liability.
	The level in the fair value hierarchy within which a fair measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety.
	Except for those assets and liabilities which are required by authoritative accounting guidance to be recorded at fair value in our balance sheets, the Company has elected not to record any other assets or liabilities at fair value. No events occurred during the fiscal years ended September 30, 2013 and 2012 that required adjustment to the recognized balances of assets or liabilities, which are recorded at fair value on a nonrecurring basis.
Grants	'
	Grants
	The Company recognizes grant proceeds as other income for reimbursement of expenses incurred upon complying with the conditions of the grant. For reimbursements of capital expenditures, the grants are recognized as a reduction of the basis of the asset upon complying with the conditions of the grant. In addition, the Company considers production incentive payments received to be economic grants and includes such amounts in other income when received, as this represents the point at which they are fixed and determinable.
Shipping and Handling	'
	Shipping and Handling
	The cost of shipping products to customers is included in cost of goods sold.  Amounts billed to a customer in a sale transaction related to shipping and handling is classified as revenue.
Income Taxes	'
	Income Taxes
	The Company is treated as a partnership for federal and state income tax purposes and generally does not incur income taxes. Instead, its earnings and losses are included in the income tax returns of the members. Therefore, no provision or liability for federal or state income taxes has been included in these financial statements.
	Differences between financial statement basis of assets and tax basis of assets is primarily related to depreciation, interest rate swaps, derivatives, inventory, compensation and capitalization and amortization of organization and start-up costs for tax purposes, whereas these costs are expensed for financial statement purposes.
	The Company has evaluated whether it has any significant tax uncertainties that would require recognition or disclosure. Primarily due to its partnership tax status, the Company does not have any significant tax uncertainties that would require recognition or disclosure.
	The Company files income tax returns in the U.S. federal jurisdiction and various states. The Company is no longer subject to income tax examinations by U.S. federal tax authorities or the states where the Company files tax returns for tax years ended on or prior to December 31, 2009.
Net Income (Loss) Per Unit	'
	Net Income (Loss) Per Unit
	Net income (loss) per unit is calculated on a basic and fully diluted basis using the weighted average units outstanding during the period.
Environmental Liabilities	'
	Environmental Liabilities
	The Company's operations are subject to environmental laws and regulations adopted by various governmental entities in the jurisdiction in which it operates. These laws require the Company to investigate and remediate the effects of the release or disposal of materials at its location. Accordingly, the Company has adopted policies, practices and procedures in the areas of pollution control, occupational health and the production, handling, storage and use of hazardous materials to prevent material, environmental or other damage, and to limit the financial liability which could result from such events. Environmental liabilities, if any, are recorded when the liability is probable and the costs can reasonably be estimated. The Company is not aware of any environmental liabilities identified as of September 30, 2013.
