Bourbon

Bourbon is an American whiskey defined by federal standards and primarily produced in the United States. It is aged in new charred American oak casks, and at least 51% of the mash bill must be corn. These rules establish the fundamental characteristics of sweetness, vanilla and caramel, while also providing oak notes and spices that support the flavor profile.

Core requirements for bourbon include: - Mash bill: at least 51% corn. The other grains can be barley, rye, or wheat in varying proportions. - Distillation and barrel entry: distilled at no more than 160 proof (80% ABV) and entered into new charred barrels at no more than 125 proof (62.5% ABV). - Aging: no fixed aging requirements under federal standards, but bourbon must be aged in new charred American oak barrels and must not be aged in reused barrels. - Production and origin: must be produced in the United States. - Age labeling and labeling: generally looser with no fixed minimum age; straight bourbon requires at least 2 years of aging, and if aged under 4 years, the age must be stated on the bottle. Bottled-in-bond bottles follow different rules.

Raw materials and mash bill describe the variations in bourbon, where corn provides sweetness and vanilla as a base note, while the other grains (barley, rye or wheat) contribute spice, body and complexity. Sour mash is a common practice, where a portion of the fermented mash is used as a starter culture in the next batch to ensure consistency.

Distillation and barrel aging form the core of bourbon's style: the mandatory use of new charred oak barrels provides strong aromas of vanilla, caramel and oak, while climate and aging time affect color, mouthfeel and flavor development. Kentucky is historically the center of bourbon, but production takes place in the United States and various regions impart regional characteristics.

Flavor profile and variations vary with mash bill and aging environment. Typical notes include vanilla, caramel, coconut, fruit and spices such as cinnamon or black pepper, where high-rye bourbons emphasize spice, and wheated bourbons emphasize a softer sweetness. Sour mash character can also affect the freshness of the aroma and the balance of the flavor.

Enjoyment and use: bourbon is often enjoyed neat or on the rocks to round out its aromas and texture, but it is also the basis for classic cocktails such as the Old Fashioned and the Manhattan, where its sweetness and body contribute to a well-balanced drink.
