Understanding Straight Bourbon Whiskey
At least 51% corn; distillation at no more than 160 proof; new charred oak entered at no more than 125 proof; at least two years of aging. Bourbon must be distilled and aged in the United States. No coloring, flavoring or blending materials. Straight is an additional designation, not a claim of single-barrel production.
Source: 27 CFR § 5.143(c), Table 1, row 5
Bottling must be at least 80 proof / 40% ABV. Shared whiskey requirement: § 5.143(a)
Under four years, an age statement is generally required. The youngest whiskey governs; a stated age may be understated but may not contradict the minimum for the designation. Age statements: § 5.74(a)–(b)
