	Financial Statement Preparation
	The unaudited condensed consolidated financial statements as of March 29, 2015, and for the quarter and two quarters ended March 29, 2015 and March 30, 2014, have been prepared by Starbucks Corporation under the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, the financial information for the quarter and two quarters ended March 29, 2015 and March 30, 2014 reflects all adjustments and accruals, which are of a normal recurring nature, necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods. In this Quarterly Report on Form 10-Q (“10-Q”) Starbucks Corporation is referred to as “Starbucks,” the “Company,” “we,” “us” or “our.”
	The financial information as of September 28, 2014 is derived from our audited consolidated financial statements and notes for the fiscal year ended September 28, 2014 (“fiscal 2014”) included in Item 8 in the Fiscal 2014 Annual Report on Form 10-K (the “10-K”). The information included in this 10-Q should be read in conjunction with the footnotes and management’s discussion and analysis of the consolidated financial statements in the 10-K.
	The results of operations for the quarter and two quarters ended March 29, 2015 are not necessarily indicative of the results of operations that may be achieved for the entire fiscal year ending September 27, 2015 ("fiscal 2015").
	Stock Split
	On April 9, 2015, we effected a two-for-one stock split of our $0.001 par value common stock for shareholders of record as of March 30, 2015. All share and per-share data in our consolidated financial statements and notes has been retroactively adjusted to reflect this stock split. We adjusted shareholders' equity to reflect the stock split by reclassifying an amount equal to the par value of the additional shares arising from the split from retained earnings to common stock during the second quarter of fiscal 2015, resulting in no net impact to shareholders' equity on our consolidated balance sheets.
	Recent Accounting Pronouncements
	In April 2015, the Financial Accounting Standards Board ("FASB") issued guidance on the financial statement presentation of debt issuance costs. This guidance requires debt issuance costs to be presented in the balance sheet as a reduction of the related debt liability rather than an asset. The guidance will become effective for us at the beginning of our first quarter of fiscal 2017 and will only result in a change in presentation of these costs on our consolidated balance sheets.
	In February 2015, the FASB issued guidance that changes the evaluation criteria for consolidation and related disclosure requirements. This guidance introduces evaluation criteria specific to limited partnerships and other similar entities, as well as amends the criteria for evaluating variable interest entities with which the reporting entity is involved and certain investment funds. The guidance will become effective for us at the beginning of our first quarter of fiscal 2017. We do not expect the adoption of this guidance will have a material impact on our consolidated financial statements.
	In May 2014, the FASB issued guidance outlining a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers that supersedes most current revenue recognition guidance. This guidance requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additionally, this guidance expands related disclosure requirements. The guidance will become effective for us at the beginning of our first quarter of fiscal 2018 and will require full or modified retrospective application. We are currently evaluating the impact this guidance will have on our consolidated financial statements as well as the expected adoption method.
	In April 2014, the FASB issued guidance that changes the criteria for reporting discontinued operations. To qualify as a discontinued operation under the amended guidance, a component or group of components of an entity that has been disposed of or is classified as held for sale must represent a strategic shift that has or will have a major effect on the entity's operations and financial results. This guidance also expands related disclosure requirements. The guidance will become effective for us at the beginning of our first quarter of fiscal 2016. We do not expect the adoption of this guidance will have a material impact on our consolidated financial statements.
	In July 2013, the FASB issued guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This guidance requires the unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset. When a deferred tax asset is not available, or the asset is not intended to be used for this purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and not netted with a deferred tax asset. The guidance became effective for us at the beginning of our first quarter of fiscal 2015 and did not have a material impact on our consolidated financial statements.
	In March 2013, the FASB issued guidance on a parent's accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. This guidance requires a parent to release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The guidance became effective for us at the beginning of our first quarter of fiscal 2015 and did not have a material impact on our consolidated financial statements.

Acquisition
	Note 2:	Acquisition
	On September 23, 2014, we entered into a tender offer bid agreement with Starbucks Coffee Japan, Ltd. ("Starbucks Japan"), at the time a 39.5% owned equity method investment, and our joint venture partner, Sazaby League, Ltd. ("Sazaby"), to acquire the remaining 60.5% ownership interest in Starbucks Japan. Acquiring Starbucks Japan further leverages our existing infrastructure to continue disciplined retail store growth and expand our presence into other channels in the Japan market, such as consumer packaged goods ("CPG"), licensing and foodservice. This acquisition was structured as a two-step tender offer.
	On October 31, 2014, we acquired Sazaby's 39.5% ownership interest in Starbucks Japan through the first tender offer step for ¥55 billion in cash, or $509 million with Japanese yen converted into U.S. dollars at a reference conversion rate of 108.13 JPY to USD, based on a spot rate that approximates the rate as of the acquisition date, bringing our total ownership in Starbucks Japan to a controlling 79% interest. The estimated fair values of the assets acquired, liabilities assumed and the noncontrolling interest are based on preliminary valuation as of the October 31, 2014 acquisition date and are subject to change as additional information about the fair value of assets acquired, liabilities assumed and noncontrolling interest becomes available.
	The following table summarizes the allocation of the total consideration to the fair values of the assets acquired and liabilities assumed as of October 31, 2014 (in millions):
	Consideration:
	Cash paid for Sazaby's 39.5% equity interest		$	508.7
	Fair value of our preexisting 39.5% equity interest		577
	Total consideration		$	1,085.70
	Fair value of assets acquired and liabilities assumed:
	Cash and cash equivalents		$	224.4
	Accounts receivable, net		37.4
	Inventories		26.4
	Prepaid expenses and other current assets		35.7
	Deferred income taxes, net (current)		23.4
	Property, plant and equipment		282.9
	Other long-term assets		141.4
	Other intangible assets		323
	Goodwill		815.6
	Total assets acquired		1,910.20
	Accounts payable		(54.5		)
	Accrued liabilities		(119.9		)
	Deferred revenue		(36.5		)
	Deferred income taxes (noncurrent)		(92.9		)
	Other long-term liabilities		(109.6		)
	Total liabilities assumed		(413.4		)
	Noncontrolling interest		(411.1		)
	Total consideration		$	1,085.70
	The assets acquired and liabilities assumed are reported within our China/Asia Pacific segment. Other current and long-term assets acquired primarily include various deposits, specifically lease and key money deposits. Accrued liabilities and other long-term liabilities assumed primarily include the financing obligations associated with the build-to-suit leases discussed below, as well as asset retirement obligations.
	The intangible assets are definite-lived and include reacquired rights, licensing agreements with Starbucks Japan's current licensees and Starbucks Japan's customer loyalty program. The reacquired rights of $305.0 million represent the fair value, calculated over the remaining original contractual period, to exclusively operate licensed Starbucks® retail stores in Japan. These rights will be amortized on a straight-line basis through March 2021, or over a period of approximately 6.4 years. The licensing agreements were valued at $15.0 million and will be amortized on a straight-line basis over a period of approximately 10.9 years, which is based on the remaining terms of the respective licensing agreements. The customer loyalty program was valued at $3.0 million and will be amortized on a straight-line basis over a period of 4.0 years, which represents the period during which we expect to benefit from these customer relationships.
	Below is a tabular summary of the acquired intangible assets as of March 29, 2015, for which the gross balances in total are $29.5 million lower than as of the October 31, 2014 acquisition date due to foreign currency translation (in millions):
		Mar 29, 2015
		Gross Carrying Amount				Accumulated Amortization			Net Carrying Amount
	Reacquired rights	$	277.2			$	(18.0	)	$	259.2
	Licensing agreements	13.6				(0.5		)	13.1
	Customer loyalty program	2.7				(0.3		)	2.4
	Total acquired definite-lived intangible assets	$	293.5			$	(18.8	)	$	274.7
	Amortization expense for these definite-lived intangible assets for the quarter and two quarters ended March 29, 2015 was $11.3 million and $19.0 million, respectively, and is estimated to be approximately $45 million each year for the next five years and approximately $50 million thereafter.
	The $815.6 million of goodwill represents the intangible assets that do not qualify for separate recognition and primarily includes the acquired current customer base, the acquired workforce including store partners in the region that have strong relationships with these customers, the existing geographic retail and online presence, and the expected geographic presence in new channels. The goodwill was allocated to the China/Asia Pacific segment and is not deductible for income tax purposes. Due to foreign currency translation, the balance of goodwill related to the acquisition declined $74.4 million to $741.2 million as of March 29, 2015.
	As a part of this acquisition we acquired a significant number of operating leases, including $7.5 million of favorable lease assets, which are included in prepaid expenses and other current assets and other long-term assets, and $15.5 million of unfavorable lease liabilities, which are included in accrued liabilities and other long-term liabilities on the consolidated balance sheets. The fair values of these assets and liabilities were determined based on market terms for similar leases as of the date of the acquisition, and will be amortized on a straight-line basis as rent expense, or a reduction of rent expense, respectively, in cost of sales including occupancy costs on the consolidated statements of earnings over the remaining terms of the leases, for which the weighted-average period was 9.4 years as of the October 31, 2014 acquisition date. We recorded a net reduction of rent expense of $0.2 million and $0.4 million for the quarter and two quarters ended March 29, 2015, respectively, in connection with the leases acquired.
	Additionally, we acquired a number of build-to-suit lease arrangements that are accounted for as financing leases. Starbucks Japan is the deemed owner of buildings under build-to-suit lease arrangements since Starbucks Japan has significant continuing involvement with the respective lessors and does not qualify for sales recognition during the lease term under sale-leaseback accounting guidance. Accordingly, we have recorded the acquired buildings in property, plant and equipment, and the assumed offsetting lease financing obligations, representing the related future minimum lease payments, in other long-term liabilities, with the current portion recorded in accrued liabilities on the consolidated balance sheets. These financing obligations will be amortized based on the terms of the related lease agreements.
	The table below summarizes our estimated minimum future rental payments under the acquired non-cancelable operating leases and lease financing arrangements as of March 29, 2015 (in millions):
		Operating Leases				Lease Financing Arrangements
	Year 1	$	87			$	3.2
	Year 2	68.2				3.1
	Year 3	53.1				3.1
	Year 4	39.6				3.1
	Year 5	31.7				3.1
	Thereafter	150.5				31.1
	Total minimum lease payments	$	430.1			$	46.7
	The fair value of the noncontrolling interest in Starbucks Japan was estimated by applying the market approach. Specifically, the fair value was determined based on the purchase price we expected to pay for the remaining 21% noncontrolling interest, which was comprised of a set market price and a premium above the market price. The market price premium is a customary business practice for public tender offer transactions in Japan, so we believe this is what a market participant would pay and should be included in the fair value determination.
	As a result of this acquisition, we remeasured the carrying value of our preexisting 39.5% equity method investment to fair value, which resulted in a pre-tax gain of $390.6 million that was presented separately as gain resulting from acquisition of joint venture within other income on the consolidated statements of earnings. The fair value of $577.0 million was calculated using an average of the income and market approach. The income approach fair value measurement was based on significant inputs that are not observable in the market and thus represents a fair value measurement categorized within Level 3 of the fair value hierarchy. Key assumptions used in estimating future cash flows included projected revenue growth and operating expenses, as well as the selection of an appropriate discount rate. Estimates of revenue growth and operating expenses were based on internal projections and considered the historical performance of stores, local market economics and the business environment impacting the stores' performance. The discount rate applied was based on Starbucks Japan's weighted-average cost of capital and included a company-specific risk premium. The market approach fair value measurement was based on the implied fair value of Starbucks Japan using the purchase price of Sazaby's 39.5% ownership interest and the expected purchase price of the 21% remaining noncontrolling interest.
	We began consolidating Starbucks Japan's results of operations and cash flows into our consolidated financial statements beginning after October 31, 2014. For the quarter and two quarters ended March 29, 2015, Starbucks Japan's revenue included in our consolidated statements of earnings was $291.3 million and $484.1 million, respectively. For the quarter and two quarters ended March 29, 2015, Starbucks Japan's net earnings included in our consolidated statements of earnings were $18.5 million and $38.8 million, respectively.
	The following table provides the supplemental pro forma revenue and net earnings of the combined entity had the acquisition date of Starbucks Japan been the first day of our first quarter of fiscal 2014 rather than during our first quarter of fiscal 2015 (in millions):
			Pro Forma (unaudited)

	Net earnings attributable to Starbucks(1)		495.6				418.5			1,097.30		1,340.30
	(1)	The pro forma net earnings attributable to Starbucks for fiscal 2014 includes the acquisition-related gain of $390.6 million, and transaction and integration costs of $0.6 million and $12.2 million for the quarter and two quarters ended March 30, 2014, respectively.
	The amounts in the supplemental pro forma earnings for the periods presented above fully eliminate intercompany transactions, apply our accounting policies and reflect adjustments for additional occupancy costs, depreciation and amortization that would have been charged assuming the same fair value adjustments to leases, property, plant and equipment and acquired intangibles had been applied on September 30, 2013. These pro forma results are unaudited and are not necessarily indicative of results of operations that would have occurred had the acquisition actually occurred in the prior year period or indicative of the results of operations for any future period.
	We initiated the second tender offer step on November 10, 2014 to acquire the remaining 21% ownership interest held by the public shareholders and option holders of Starbucks Japan's common stock, with the objective of acquiring all of the remaining outstanding shares including outstanding stock options. At the close of the second tender offer period on December 22, 2014, we funded the second tender offer step to acquire an additional 14.7% ownership interest for ¥31 billion in cash, or $258 million with Japanese yen converted into U.S. dollars at a reference conversion rate of 120.39 JPY to USD. However, we did not complete the second tender offer nor obtain control of these shares until the settlement date of December 29, 2014, which was the first day of our second quarter of fiscal 2015.
	Subsequent to the completion of the second tender offer step, we commenced a cash-out procedure under Japanese law (the "Cash-out") to acquire all remaining shares of Starbucks Japan (an approximate 6.3% interest). On March 26, 2015, we obtained control of these shares resulting in 100% ownership of Starbucks Japan. The purchase price for the Cash-out, which we expect to pay in the third quarter of fiscal 2015, is ¥13.5 billion, or approximately $113.3 million, with Japanese yen converted into U.S. dollars at a reference conversion rate of 118.99 JPY to USD, which is reflected in accrued liabilities on our consolidated balance sheet as of March 29, 2015.
	For the first quarter of fiscal 2015, net earnings attributable to noncontrolling interests in our consolidated statement of earnings related to Starbucks Japan reflects the 21% of minority shareholders’ interests that we did not own as of the end of the first quarter of fiscal 2015. For the second quarter of fiscal 2015, net earnings attributable to noncontrolling interests in our consolidated statement of earnings related to Starbucks Japan reflects the approximate 6.3% of minority shareholders’ interests that we did not obtain control of until March 26, 2015.
The following table shows the effects of the change in Starbucks ownership interest in Starbucks Japan on Starbucks equity:
	Two Quarters Ended

Change from net earnings attributable to Starbucks and transfers (to)/from noncontrolling interest	$	1,480.00			$	967.6
During the quarter and two quarters ended March 29, 2015, we incurred approximately $0.3 million and $11.3 million, respectively, of acquisition-related costs, such as regulatory, legal, and advisory fees, which we have recorded within unallocated corporate general and administrative expenses.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments
	Interest Rates
	Depending on market conditions, we enter into interest rate swap agreements to hedge the variability in cash flows due to changes in the benchmark interest rate related to anticipated debt issuances. These agreements are cash settled at the time of the pricing of the related debt. The effective portion of the derivative's gain or loss is recorded in accumulated other comprehensive income ("AOCI") and is subsequently reclassified to interest expense over the life of the related debt.
	During the first quarter of fiscal 2015, we entered into forward-starting interest rate swap agreements with an aggregate notional amount of $250.0 million related to a potential debt issuance in fiscal 2015.
	Foreign Currency
	To reduce cash flow volatility from foreign currency fluctuations, we enter into forward and swap contracts to hedge portions of cash flows of anticipated revenue streams, inventory purchases, and principal and interest payments on intercompany loans in currencies other than the entity's functional currency. The effective portion of the derivative's gain or loss is recorded in AOCI and is subsequently reclassified to revenue, cost of sales, or interest income and other, net, respectively, when the hedged exposure affects net earnings.
	In connection with the acquisition of Starbucks Japan that is discussed in Note 2, Acquisition, we entered into cross-currency swap contracts during the first quarter of fiscal 2015 to hedge the foreign currency transaction risk of certain yen-denominated intercompany loans with a total notional value of ¥73.5 billion, or approximately $618 million as of March 29, 2015. Gains and losses from these swaps offset the changes in value of interest and principal payments as a result of changes in foreign exchange rates, which are also recorded in net interest income and other on the consolidated statements of earnings. These swaps have been designated as cash flow hedges and mature in September 2016 and November 2024 at the same time as the related loans. There are no credit-risk-related contingent features associated with these swaps, although we may hold or post collateral depending upon the gain or loss position of the swap agreement.
	We also enter into forward contracts to hedge the foreign currency exposure of our net investment in certain foreign operations. The effective portion of the derivative's gain or loss is recorded in AOCI and will be subsequently reclassified to net earnings when the hedged net investment is either sold or substantially liquidated.
	As a result of our acquisition of Starbucks Japan, we reclassified the pretax cumulative net gains in AOCI of $7.2 million related to our net investment derivative instruments used to hedge our preexisting 39.5% equity method investment in Starbucks Japan into earnings, which was included in the gain resulting from acquisition of joint venture line item on the consolidated statements of earnings. These gains offset the cumulative translation adjustment loss balance associated with our preexisting investment included in the calculation of the remeasurement gain, which is described further in Note 2, Acquisition.
	To mitigate the foreign exchange risk of certain balance sheet items, we enter into foreign currency forward contracts that are not designated as hedging instruments. Gains and losses from these derivatives are largely offset by the financial impact of translating foreign currency denominated payables and receivables; both are recorded in net interest income and other.
	Commodities
	Depending on market conditions, we enter into coffee futures contracts and collars (the combination of a purchased call option and a sold put option) to hedge a portion of anticipated cash flows under our price-to-be-fixed green coffee contracts, which are described further in Note 5, Inventories. The effective portion of each derivative's gain or loss is recorded in AOCI and is subsequently reclassified to cost of sales when the hedged exposure affects net earnings.
	To mitigate the price uncertainty of a portion of our future purchases of dairy products and diesel fuel, we enter into dairy swap contracts, futures and collars, as well as instruments used to hedge diesel fuel exposure that are not designated as hedging instruments. Gains and losses from these derivatives are recorded in net interest income and other and help to offset price fluctuations on our dairy purchases and the financial impact of diesel fuel fluctuations on our shipping costs, which are included in cost of sales including occupancy costs.

	As of March 29, 2015, we had committed to purchasing green coffee totaling $787 million under fixed-price contracts and an estimated $257 million under price-to-be-fixed contracts. As of March 29, 2015, approximately $19 million of our price-to-be-fixed contracts were effectively fixed through the use of futures contracts and approximately $17 million were price-protected through the use of collar instruments. Price-to-be-fixed contracts are purchase commitments whereby the quality, quantity, delivery period, and other negotiated terms are agreed upon, but the date, and therefore the price, at which the base “C” coffee commodity price component will be fixed has not yet been established. For these types of contracts, either Starbucks or the seller has the option to “fix” the base “C” coffee commodity price prior to the delivery date. Until prices are fixed, we estimate the total cost of these purchase commitments. We believe, based on relationships established with our suppliers in the past, the risk of non-delivery on these purchase commitments is remote.

	Potential dilutive shares consist of the incremental common shares issuable upon the exercise of outstanding stock options (both vested and non-vested) and unvested RSUs, calculated using the treasury stock method. The calculation of dilutive shares outstanding excludes out-of-the-money stock options (i.e., such options’ exercise prices were greater than the average market price of our common shares for the period) because their inclusion would have been antidilutive. Out-of-the-money stock options totaled approximately 0.1 million and 5.7 million as of March 29, 2015 and March 30, 2014, respectively.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In April 2015, the Financial Accounting Standards Board ("FASB") issued guidance on the financial statement presentation of debt issuance costs. This guidance requires debt issuance costs to be presented in the balance sheet as a reduction of the related debt liability rather than an asset. The guidance will become effective for us at the beginning of our first quarter of fiscal 2017 and will only result in a change in presentation of these costs on our consolidated balance sheets.
	In February 2015, the FASB issued guidance that changes the evaluation criteria for consolidation and related disclosure requirements. This guidance introduces evaluation criteria specific to limited partnerships and other similar entities, as well as amends the criteria for evaluating variable interest entities with which the reporting entity is involved and certain investment funds. The guidance will become effective for us at the beginning of our first quarter of fiscal 2017. We do not expect the adoption of this guidance will have a material impact on our consolidated financial statements.
	In May 2014, the FASB issued guidance outlining a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers that supersedes most current revenue recognition guidance. This guidance requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additionally, this guidance expands related disclosure requirements. The guidance will become effective for us at the beginning of our first quarter of fiscal 2018 and will require full or modified retrospective application. We are currently evaluating the impact this guidance will have on our consolidated financial statements as well as the expected adoption method.
	In April 2014, the FASB issued guidance that changes the criteria for reporting discontinued operations. To qualify as a discontinued operation under the amended guidance, a component or group of components of an entity that has been disposed of or is classified as held for sale must represent a strategic shift that has or will have a major effect on the entity's operations and financial results. This guidance also expands related disclosure requirements. The guidance will become effective for us at the beginning of our first quarter of fiscal 2016. We do not expect the adoption of this guidance will have a material impact on our consolidated financial statements.
	In July 2013, the FASB issued guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This guidance requires the unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset. When a deferred tax asset is not available, or the asset is not intended to be used for this purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and not netted with a deferred tax asset. The guidance became effective for us at the beginning of our first quarter of fiscal 2015 and did not have a material impact on our consolidated financial statements.
	In March 2013, the FASB issued guidance on a parent's accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. This guidance requires a parent to release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The guidance became effective for us at the beginning of our first quarter of fiscal 2015 and did not have a material impact on our consolidated financial statements.
