Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, the Company used various methods including market, income and cost approaches. Based on these approaches, the Company often utilized certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and/or the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated, or generally unobservable inputs. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observable inputs used in the valuation techniques, the Company is required to provide the following information according to the fair value hierarchy. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories: Level 1 - Valuations for assets and liabilities traded in active markets from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 - Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained from third-party pricing services for identical or similar assets or liabilities. Level 3 - Valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities. A description of the valuation methodologies used for instruments measured at fair value, including the general classifications of such instruments pursuant to the valuation hierarchy, is set below. Put Option liability . The put option liability consists of an agreement between the Company and ICM that contains a conditional obligation to repurchase feature. In accordance with accounting for put options as a liability, the Company calculated the fair value of the put option under Level 3, using a Monte Carlo Simulation model. Derivative financial instruments . Commodity futures and exchange traded options are reported at fair value utilizing Level 1 inputs. For these contracts, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes and live trading levels from the Chicago Mercantile Exchange (“ CME ”) market. Ethanol contracts are reported at fair value utilizing Level 2 inputs from third-party pricing services. Forward purchase contracts are reported at fair value utilizing Level 2 inputs. For these contracts, the Company obtains fair value measurements from local grain terminal values. The fair value measurements consider observable data that may include live trading bids from local elevators and processing plants which are based on the CME market. The following table summarizes financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2018 and September 30, 2017 , categorized by the level of the valuation inputs within the fair value hierarchy (in '000s): June 30, 2018 Level 1 Level 2 Level 3 Assets: Derivative financial instruments $ 960 $ — $ — Liabilities: Derivative financial instruments 93 1,453 — Put option liability — — 5,700 September 30, 2017 Level 1 Level 2 Level 3 Assets: Derivative financial instruments $ 190 $ — $ — Liabilities: Derivative financial instruments 100 911 — Put option liability — — 5,700 The following table summarizes the assumptions used in computing the fair value of the put options subject to fair value accounting at June 30, 2018 and September 30, 2017 June 30, 2018 September 30, 2017 Put option assumptions: Risk-free interest rate 1.34 % 1.34 % Expected volatility 26 % 26 % Expected life (years) 1.25 1.25 Exercise price $10,897 $10,897 Company unit price $5,670 $5,670 The following table reflects the activity for liabilities measured at fair value using Level 3 inputs during the three months ended June 30, 2018 and for Fiscal 2017 that ended September 30, 2017 : June 30, 2018 September 30, 2017 Beginning Balance $ 5,700 $ 6,100 Change in Value — (400 ) Ending Balance $ 5,700 $ 5,700

Related Party Transaction, Due from (to) Related Party [Abstract]
Related Party Transactions	Related Party Transactions Bunge Under the Ethanol Agreement, the Company sells Bunge all of the ethanol produced by the Company, and Bunge purchases the same. The Company pays Bunge a percentage fee for ethanol sold by Bunge, subject to a minimum and maximum annual fee. The initial term of the Ethanol Agreement expires on December 31, 2019, however it will automatically renew for one five-year term unless Bunge provides the Company with notice of election not to renew no later than 180 days prior to the expiration of the initial term. The Company incurred ethanol marketing expenses of $0.4 million during both of the three months ended June 30, 2018 and 2017 , and $1.1 million during both of the nine months ended June 30, 2018 and 2017 , under the Ethanol Agreement. Under the DG Purchase Agreement, Bunge purchases all distillers grains produced by the Company, and receives a fee based on the net sale price of distillers grains, subject to a minimum and maximum annual fee. The initial term of the DG Purchase Agreement expires on December 31, 2019 and will automatically renew for one additional five year term unless Bunge provides the Company with notice of election not to renew no later than 180 days prior to the expiration of the initial term. The Company incurred distillers grains marketing expenses of $0.3 million during both of the three months ended June 30, 2018 and 2017 , and $0.9 and $0.8 million during the nine months ended June 30, 2018 and 2017 , respectively. The Company and Bunge entered into an Amended and Restated Grain Feedstock Agency Agreement on December 5, 2014 (the “ Agency Agreement ”). The Agency Agreement provides that Bunge procure corn for the Company and that the Company pay Bunge a per bushel fee, subject to a minimum and maximum annual fee. The initial term of the Agency Agreement expires on December 31, 2019 and will automatically renew for one additional five year term unless Bunge provides the Company with notice of election not to renew no later than 180 days prior to the expiration of the initial term. Expenses for corn procurement by Bunge were $0.2 million during both of the three months ended June 30, 2018 and 2017 , and $0.5 million during both of the nine months ended June 30, 2018 and $2017 . Starting with the 2015 crop year, the Company began using corn containing Syngenta Seeds, Inc.’s proprietary Enogen® technology (“ Enogen Corn ”) for a portion of its ethanol production needs. The Company contracts directly with growers to produce Enogen Corn for sale to the Company. The Company has contracted for 28,900 acres of Enogen corn for the fiscal year ending September 30, 2018 . Concurrent with the Agency Agreement, the Company and Bunge entered into a Services Agreement regarding Enogen Corn purchases (the “ Services Agreement ”). Under this Services Agreement, the Company originates all Enogen Corn contracts for its facility and Bunge assists the Company with certain administrative matters related to Enogen Corn, including facilitating delivery to the facility. The Company pays Bunge a per bushel service fee. The initial term of the Services Agreement expires on December 31, 2019 and will automatically renew for one additional five year term unless Bunge provides the Company with notice of election not to renew no later than 180 days prior to the expiration of the initial term. Expenses under the Services Agreement are included as part of the Amended and Restated Grain Feedstock Agency Agreement discussed above. On June 26, 2009, the Company executed a Railcar Agreement with Bunge for the lease of 325 ethanol cars and 300 hopper cars which are used for the delivery and marketing of ethanol and distillers grains (in November of 2016, the number of ethanol cars was reduced to 323 , which is in addition to the hopper car reductions of one each in November 2013 and January 2015 to 298 ). Under the Railcar Agreement, the Company leases railcars for terms lasting 120 months and continuing on a month-to-month basis thereafter. The Railcar Agreement will terminate upon the expiration of all railcar leases. On November 1, 2016, the agreement was amended to provide for 96 hopper cars to be side-leased back to Bunge. Expenses under the Railcar Agreement were $1.0 million during both of the three months ended June 30, 2018 and 2017 , net of subleases and accretion, and were $2.9 million and $3.5 million for the nine months ended June 30, 2018 and 2017 , respectively. The Company has subleased 92 hopper cars to two unrelated third parties, which sublease expires March 25, 2019. In June 2018, one of the third party customers entered into an assignment agreement for their 52 hopper cars with the Company and Bunge which will be phased in over the fourth quarter, and the start of the first quarter in our fiscal year ending September 30, 2019. SIRE will receive an up front assignment payment, and the net result will be financially neutral, and the number of side-leased railcars by SIRE remains the same. The Company will continue to work with Bunge to determine the need for ethanol and hopper cars in light of current market conditions, and the expected conditions in the fiscal year ending September 30, 2018 (" Fiscal 2018 ") and future fiscal years. ICM On February 26, 2018, the Company executed an Equipment Purchase and Installation Agreement with ICM, Inc for plant equipment totaling $3.9 million . As of June 30, 2018

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Other Information The accompanying financial statements as of and for the three and nine months ended June 30, 2018 and 2017 are unaudited and reflect all adjustments (consisting only of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the financial position and operating results for the interim periods. These unaudited financial statements and notes should be read in conjunction with the audited financial statements and notes thereto, for the fiscal year ended September 30, 2017 contained in the Company’s Annual Report on Form 10-K. The results of operations for the interim periods presented are not necessarily indicative of the results for the entire year. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Revenue Recognition The Company sells ethanol and related products pursuant to marketing agreements. Revenues are recognized when the marketing company has taken title to the product, prices are fixed or determinable and collectability is reasonably assured. The Company’s products are generally shipped FOB loading point, and recorded as a sale upon delivery of the applicable bill of lading. The Company’s ethanol sales are handled through an ethanol purchase agreement (the “ Ethanol Agreement ”) with Bunge North America, Inc. (“ Bunge ”). Syrup and distillers grains (co-products) are sold through a distillers grains agreement (the “ DG Agreement ”) with Bunge, based on market prices. The Company markets and distributes all of the corn oil it produces directly to end users at market prices. Carbon dioxide is sold through a Carbon Dioxide Purchase and Sale Agreement (the “ CO2 Agreemen t”) with Air Products and Chemicals, Inc. Marketing fees, agency fees, and commissions due to the marketer are calculated separately from the settlement for the sale of the ethanol products and co-products and are included as a component of cost of goods sold. Shipping and handling costs incurred by the Company for the sale of ethanol and co-products are included in cost of goods sold. Accounts Receivable Accounts receivable are recorded at original invoice amounts less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Most of the accounts receivable are with Bunge. Management determines the allowance for doubtful accounts by regularly evaluating customer receivables and considering the customer’s financial condition, credit history and current economic conditions. As of June 30, 2018 and September 30, 2017 , management had determined no allowance was necessary. Accounts receivables are written off when deemed uncollectable and recoveries of receivables written off are recorded when received. Investment in Commodities Contracts, Derivative Instruments and Hedging Activities The Company’s operations and cash flows are subject to fluctuations due to changes in commodity prices. The Company is subject to significant market risk with respect to the price and availability of corn, the principal raw material used to produce ethanol and ethanol by-products. Exposure to commodity price risk results from its dependence on corn in the ethanol production process. In general, rising corn prices result in lower profit margins and, therefore, represent unfavorable market conditions. This is especially true when market conditions do not allow the Company to pass along increased corn costs to customers. The availability and price of corn is subject to wide fluctuations due to unpredictable factors such as weather conditions, farmer planting decisions, governmental policies with respect to agriculture and international trade and global demand and supply. To minimize the risk and the volatility of commodity prices, primarily related to corn and ethanol, the Company uses various derivative instruments, including forward corn, ethanol, and distillers grains purchase and sales contracts, over-the-counter and exchange-traded futures and option contracts. When the Company has sufficient working capital available, it enters into derivative contracts to hedge its exposure to price risk related to forecasted corn needs and forward corn purchase contracts. Management has evaluated the Company’s contracts to determine whether the contracts are derivative instruments. Certain contracts that literally meet the definition of a derivative may be exempted from derivative accounting 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. Gains and losses on contracts that are designated as normal purchases or normal sales contracts are not recognized until quantities are delivered or utilized in production. The Company applies the normal sale exemption to forward contracts relating to ethanol, distillers grains, and corn oil and therefore these forward contracts are not marked to market. As of June 30, 2018 , the Company was committed to sell 2.3 million gallons of ethanol, 0.1 million tons of wet and dried distillers grains and 2.5 million pounds of corn oil. Corn purchase contracts are treated as derivative financial instruments. Changes in market value of forward corn contracts, which are marked to market each period, are included in costs of goods sold. As of June 30, 2018 , the Company was committed to purchasing 4.9 million bushels of corn on a forward contract basis resulting in a total commitment of $18.6 million . In addition, the Company was committed to purchase 0.2 million bushels of corn on basis contracts. In addition, the Company enters into short-term cash, options and futures contracts as a means of managing exposure to changes in commodity prices. The Company enters into derivative contracts to hedge the exposure to volatile commodity price fluctuations. The Company maintains a risk management strategy that uses derivative instruments to minimize significant, unanticipated earnings fluctuations caused by market volatility. The Company’s specific goal is to protect itself from large moves in commodity costs. All derivatives are designated as non-hedge derivatives and the contracts will be accounted for at fair value. Although the contracts will be effective economic hedges of specified risks, they are not designated as and accounted for as hedging instruments. Derivatives not designated as hedging instruments along with cash held by brokers at June 30, 2018 and September 30, 2017 at market value are as follows: Balance Sheet Classification June 30, 2018 September 30, 2017 in 000's in 000's Futures and option contracts In gain position $ 960 $ 190 In loss position (93 ) (100 ) Cash due to broker (506 ) (67 ) Current asset 361 23 Forward contracts, corn 1,453 911 Current liability 1,453 911 Net futures, options, and forward contracts $ (1,092 ) $ (888 ) The net realized and unrealized gains and losses on the Company’s derivative contracts for the three and nine months ended June 30, 2018 and 2017 consist of the following: Three Months Ended Nine Months Ended Statement of Operations Classification June 30, 2018 June 30, 2017 June 30, 2018 June 30, 2017 in 000's in 000's in 000's in 000's Net realized and unrealized (gains) losses related to: Forward purchase corn contracts Cost of Goods Sold $ 1,803 $ (816 ) $ 2,121 $ 515 Futures and option corn contracts Cost of Goods Sold (2,272 ) (564 ) (2,944 ) (1,180 ) Inventory Inventory is stated at the lower of weighted average cost or net realizable value. In the valuation of inventories and purchase commitments, net realizable value is defined as estimated selling price in the ordinary course of business less reasonable predictable costs of completion, disposal and transportation. Put Option liability The put option liability consists of an agreement between the Company and ICM, Inc. that contains a conditional obligation to repurchase feature. In accordance with accounting for put options as a liability, the Company calculated the fair value of the put option under Level 3, using a valuation model called the Monte Carlo Simulation. Using this model, the estimated value did not change significantly from September 30, 2017 to June 30, 2018 . Income Per Unit Basic income per unit is calculated by dividing net income by the weighted average units outstanding for each period. Basic earnings and diluted per unit data were computed as follows (in thousands except per unit data): Three Months Ended Nine Months Ended June 30, 2018 June 30, 2017 March 31, 2018 June 30, 2017 Numerator: Net income (loss) for basic earnings per unit $ (3,245 ) $ 1,929 $ (2,899 ) $ 9,626 Net income (loss) for diluted earnings per unit $ (3,245 ) $ 1,929 $ (2,899 ) $ 9,626 Denominator: Weighted average units outstanding - basic 13,327 13,327 13,327 13,327 Weighted average units outstanding - diluted 13,327 14,384 13,327 14,423 Income (loss) per unit - basic $ (243.49 ) $ 144.74 $ (217.53 ) $ 722.29 Income (loss) per unit - diluted $ (243.49 ) $ 134.11 $ (217.53 ) $ 667.41 Recently Issued Accounting Pronouncements Revenue Recognition In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes all existing revenue recognition requirements, including most industry-specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. The new standard will be effective for us on October 1, 2018, the start of our new fiscal year. The Company expects to have enhanced disclosures, but does not expect the new standard to have a material impact on the Company's financial statements.

Basis Of Presentation And Other Information	Basis of Presentation and Other Information The accompanying financial statements as of and for the three and nine months ended June 30, 2018 and 2017 are unaudited and reflect all adjustments (consisting only of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the financial position and operating results for the interim periods. These unaudited financial statements and notes should be read in conjunction with the audited financial statements and notes thereto, for the fiscal year ended September 30, 2017
Use Of Estimates	Use of EstimatesThe preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from these estimates.
Revenue Recognition	Revenue Recognition The Company sells ethanol and related products pursuant to marketing agreements. Revenues are recognized when the marketing company has taken title to the product, prices are fixed or determinable and collectability is reasonably assured. The Company’s products are generally shipped FOB loading point, and recorded as a sale upon delivery of the applicable bill of lading. The Company’s ethanol sales are handled through an ethanol purchase agreement (the “ Ethanol Agreement ”) with Bunge North America, Inc. (“ Bunge ”). Syrup and distillers grains (co-products) are sold through a distillers grains agreement (the “ DG Agreement ”) with Bunge, based on market prices. The Company markets and distributes all of the corn oil it produces directly to end users at market prices. Carbon dioxide is sold through a Carbon Dioxide Purchase and Sale Agreement (the “ CO2 Agreemen
Accounts Receivable	Accounts Receivable Accounts receivable are recorded at original invoice amounts less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Most of the accounts receivable are with Bunge. Management determines the allowance for doubtful accounts by regularly evaluating customer receivables and considering the customer’s financial condition, credit history and current economic conditions. As of June 30, 2018 and September 30, 2017 , management had determined no
Investment In Commodities Contracts, Derivative Instruments And Hedging Activities	Investment in Commodities Contracts, Derivative Instruments and Hedging Activities The Company’s operations and cash flows are subject to fluctuations due to changes in commodity prices. The Company is subject to significant market risk with respect to the price and availability of corn, the principal raw material used to produce ethanol and ethanol by-products. Exposure to commodity price risk results from its dependence on corn in the ethanol production process. In general, rising corn prices result in lower profit margins and, therefore, represent unfavorable market conditions. This is especially true when market conditions do not allow the Company to pass along increased corn costs to customers. The availability and price of corn is subject to wide fluctuations due to unpredictable factors such as weather conditions, farmer planting decisions, governmental policies with respect to agriculture and international trade and global demand and supply. To minimize the risk and the volatility of commodity prices, primarily related to corn and ethanol, the Company uses various derivative instruments, including forward corn, ethanol, and distillers grains purchase and sales contracts, over-the-counter and exchange-traded futures and option contracts. When the Company has sufficient working capital available, it enters into derivative contracts to hedge its exposure to price risk related to forecasted corn needs and forward corn purchase contracts. Management has evaluated the Company’s contracts to determine whether the contracts are derivative instruments. Certain contracts that literally meet the definition of a derivative may be exempted from derivative accounting 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. Gains and losses on contracts that are designated as normal purchases or normal sales contracts are not recognized until quantities are delivered or utilized in production. The Company applies the normal sale exemption to forward contracts relating to ethanol, distillers grains, and corn oil and therefore these forward contracts are not marked to market. As of June 30, 2018 , the Company was committed to sell 2.3 million gallons of ethanol, 0.1 million tons of wet and dried distillers grains and 2.5 million pounds of corn oil. Corn purchase contracts are treated as derivative financial instruments. Changes in market value of forward corn contracts, which are marked to market each period, are included in costs of goods sold. As of June 30, 2018 , the Company was committed to purchasing 4.9 million bushels of corn on a forward contract basis resulting in a total commitment of $18.6 million . In addition, the Company was committed to purchase 0.2 million bushels of corn on basis contracts. In addition, the Company enters into short-term cash, options and futures contracts as a means of managing exposure to changes in commodity prices. The Company enters into derivative contracts to hedge the exposure to volatile commodity price fluctuations. The Company maintains a risk management strategy that uses derivative instruments to minimize significant, unanticipated earnings fluctuations caused by market volatility. The Company’s specific goal is to protect itself from large moves in commodity costs. All derivatives are designated as non-hedge derivatives and the contracts will be accounted for at fair value. Although the contracts will be effective economic hedges of specified risks, they are not designated as and accounted for as hedging instruments. Derivatives not designated as hedging instruments along with cash held by brokers at June 30, 2018 and September 30, 2017 at market value are as follows: Balance Sheet Classification June 30, 2018 September 30, 2017 in 000's in 000's Futures and option contracts In gain position $ 960 $ 190 In loss position (93 ) (100 ) Cash due to broker (506 ) (67 ) Current asset 361 23 Forward contracts, corn 1,453 911 Current liability 1,453 911 Net futures, options, and forward contracts $ (1,092 ) $ (888 ) The net realized and unrealized gains and losses on the Company’s derivative contracts for the three and nine months ended June 30, 2018 and 2017 consist of the following: Three Months Ended Nine Months Ended Statement of Operations Classification June 30, 2018 June 30, 2017 June 30, 2018 June 30, 2017 in 000's in 000's in 000's in 000's Net realized and unrealized (gains) losses related to: Forward purchase corn contracts Cost of Goods Sold $ 1,803 $ (816 ) $ 2,121 $ 515 Futures and option corn contracts Cost of Goods Sold (2,272 ) (564 ) (2,944 ) (1,180 )
Inventory	InventoryInventory is stated at the lower of weighted average cost or net realizable value. In the valuation of inventories and purchase commitments, net realizable value is defined as estimated selling price in the ordinary course of business less reasonable predictable costs of completion, disposal and transportation.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Put Option liability The put option liability consists of an agreement between the Company and ICM, Inc. that contains a conditional obligation to repurchase feature. In accordance with accounting for put options as a liability, the Company calculated the fair value of the put option under Level 3, using a valuation model called the Monte Carlo Simulation. Using this model, the estimated value did not change significantly from September 30, 2017 to June 30, 2018
