Accounting Policies [Abstract]
Principles of consolidation	Principles of consolidation. Our consolidated financial statements include the accounts of all subsidiaries in which we have a controlling financial interest. We eliminate all intercompany transactions.
Estimates	Estimates. To prepare financial statements that conform with GAAP, our management must make informed estimates that affect how we report revenues, expenses, assets, and liabilities, including contingent assets and liabilities. Actual results could differ from these estimates.
Cash equivalents	Cash equivalents. Cash equivalents include bank demand deposits and all highly liquid investments with original maturities of three months or less.
Allowance for doubtful accounts	Allowance for doubtful accounts. We evaluate the collectability of accounts receivable based on a combination of factors. When we are aware of circumstances that may impair a specific customer’s ability to meet its financial obligations, we record a specific allowance to reduce the net recognized receivable to the amount we believe will be collected. We write off the uncollectable amount against the allowance when we have exhausted our collection efforts. The allowance for doubtful accounts was $7 as of both April 30, 2018 and 2019.
Inventories	Inventories. Inventories are valued at the lower of cost or net realizable value. Approximately 52% of our consolidated inventories are valued using the last-in, first-out (LIFO) cost method, which we use for the majority of our U.S. inventories. We value the remainder of our inventories primarily using the first-in, first-out (FIFO) cost method. FIFO cost approximates current replacement cost. If we had used the FIFO method for all inventories, they would have been $290 and $303 higher than reported at April 30, 2018 and 2019, respectively. Because we age most of our whiskeys in barrels for three to six years, we bottle and sell only a portion of our whiskey inventory each year. Following industry practice, we classify all barreled whiskey as a current asset. We include warehousing, insurance, ad valorem taxes, and other carrying charges applicable to barreled whiskey in inventory costs. We classify bulk wine, agave inventories, tequila, and liquid in bottling tanks as work in process.
Property, plant, and equipment	Property, plant, and equipment. We state property, plant, and equipment at cost less accumulated depreciation. We calculate depreciation on a straight-line basis using our estimates of useful life, which are 20–40 years for buildings and improvements; 3–10 years for machinery, equipment, vehicles, furniture, and fixtures; and 3–7 years for capitalized software. We assess our property, plant, and equipment for impairment whenever events or changes in circumstances indicate that the carrying value of those assets may not be recoverable. When we do not expect to recover the carrying value of an asset (or asset group) through undiscounted future cash flows, we write it down to its estimated fair value. We determine fair value using discounted estimated future cash flows, considering market values for similar assets when available. When we retire or dispose of property, plant, and equipment, we remove its cost and accumulated depreciation from our balance sheet and reflect any gain or loss in operating income. We expense the costs of repairing and maintaining our property, plant, and equipment as we incur them.
Goodwill and other intangible assets	Goodwill and other intangible assets. We have obtained most of our brands by acquiring other companies. When we acquire another company, we first allocate the purchase price to identifiable assets and liabilities, including intangible brand names and trademarks (“brand names”), based on estimated fair value. We then record any remaining purchase price as goodwill. We do not amortize goodwill or other intangible assets with indefinite lives. We consider all of our brand names to have indefinite lives. We assess our goodwill and other indefinite-lived intangible assets for impairment at least annually. Goodwill is impaired when the carrying amount of the related reporting unit exceeds its estimated fair value, in which case we write down the goodwill by the amount of the excess (limited to the carrying amount of the goodwill). We estimate the reporting unit’s fair value using discounted estimated future cash flows or market information. Similarly, a brand name is impaired when its carrying amount exceeds its estimated fair value, in which case we write down the brand name to its estimated fair value. We typically estimate the fair value of a brand name using either the “relief from royalty” or “excess earnings” method. We also consider market values for similar assets when available. Considerable management judgment is necessary to estimate fair value, including the selection of assumptions about future cash flows, discount rates, and royalty rates. We have the option, before quantifying the fair value of a reporting unit or brand name, to evaluate qualitative factors to assess whether it is more likely than not that our goodwill or brand names are impaired. If we determine that is not the case, then we are not required to quantify the fair value. That assessment also takes considerable management judgment.
Revenue recognition	Revenue recognition. Our net sales predominantly reflect global sales of beverage alcohol consumer products. We sell these products under contracts with different types of customers, depending on the market. The customer is most often a distributor, wholesaler, or retailer. Each contract typically includes a single performance obligation to transfer control of the products to the customer. Depending on the contract, control is transferred when the products are either shipped or delivered to the customer, at which point we recognize the transaction price for those products as net sales. The transaction price recognized at that point reflects our estimate of the consideration to be received in exchange for the products. The actual amount may ultimately differ due to the effect of various customer incentives and trade promotion activities. In making our estimates, we consider our historical experience and current expectations, as applicable. Subsequent adjustments recognized for changes in estimated transaction prices are typically not material. Net sales exclude taxes we collect from customers that are imposed by various governments on our sales, and are reduced by payments to customers unless made in exchange for distinct goods or services with fair values approximating the payments. Net sales include any amounts we bill customers for shipping and handling activities related to the products. We recognize the cost of those activities in cost of sales during the same period in which we recognize the related net sales. Sales returns, which are permitted only in limited situations, are not material. Customer payment terms generally range from 30 to 90 days. There are no significant amounts of contract assets or liabilities.
Cost of sales	Cost of sales. Cost of sales includes the costs of receiving, producing, inspecting, warehousing, insuring, and shipping goods sold during the period.
Advertising costs	Advertising costs. We expense the costs of advertising during the year when the advertisements first take place.
Selling, general, and administrative expenses	Selling, general, and administrative expenses. Selling, general, and administrative expenses include the costs associated with our sales force, administrative staff and facilities, and other expenses related to our non-manufacturing functions.
Stock-based compensation	Stock-based compensation. We use stock-based awards as part of our incentive compensation for eligible employees and directors. We recognize the grant-date fair value of an award as compensation expense on a straight-line basis over the requisite service period, which typically corresponds to the vesting period for the award. Upon forfeiture of an award prior to vesting, we reverse any previously-recognized compensation expense related to that award. We classify stock-based compensation expense within selling, general, and administrative expenses. As we recognize compensation expense for a stock-based award, we concurrently recognize a related deferred tax asset. The subsequent vesting or exercise of the award will generally result in an actual tax benefit that differs from the deferred tax asset that had been recorded. The excess (deficiency) of the actual tax benefit over (under) the previously-recorded tax asset is recognized as income tax benefit (expense) on the date of vesting or exercise.
Income taxes	Income taxes. We base our annual provision for income taxes on the pre-tax income reflected in our consolidated statement of operations. We establish deferred tax liabilities or assets for temporary differences between GAAP and tax reporting bases and later adjust them to reflect changes in tax rates expected to be in effect when the temporary differences reverse. We record a valuation allowance as necessary to reduce a deferred tax asset to the amount that we believe is more likely than not to be realized. We do not provide deferred income taxes on undistributed earnings of foreign subsidiaries that we expect to permanently reinvest. We record a deferred tax charge in prepaid taxes for the difference between GAAP and tax reporting bases with respect to the elimination of intercompany profit in ending inventory. We assess our uncertain income tax positions in two steps. First, we evaluate whether the tax position will more likely than not, based on its technical merits, be sustained upon examination, including resolution of any related appeals or litigation. For a tax position that does not meet this first criterion, we recognize no tax benefit. For a tax position that does meet the first criterion, we recognize a tax benefit in an amount equal to the largest amount of benefit that we believe has more than a 50% likelihood of being realized upon ultimate resolution. We record interest and penalties on uncertain tax positions as income tax expense.
Foreign currency transactions and translation	Foreign currency transactions and translation. We report all gains and losses from foreign currency transactions (those denominated in a currency other than the entity’s functional currency) in current income. The U.S. dollar is the functional currency for most of our consolidated entities. The local currency is the functional currency for some of our consolidated foreign entities. We translate the financial statements of those foreign entities into U.S. dollars, using the exchange rate in effect at the balance sheet date to translate assets and liabilities, and using the average exchange rate for the reporting period to translate income and expenses. We record the resulting translation adjustments in other comprehensive income (loss).
