Popular Bourbons whiskey is a type of American whiskey made primarily from corn and aged in charred oak barrels. To be considered bourbon, it must be produced in the United States, made from at least 51% corn, distilled to no more than 80% alcohol by volume (ABV), and aged in new, charred oak barrels at no more than 62.5% ABV. Bourbon also cannot contain any added flavoring or coloring, and must be bottled at no less than 40% ABV.

Bourbon is known for its sweet and smooth flavor profile, with notes of caramel, vanilla, and oak. It is a popular spirit both in the United States and internationally, and can be enjoyed neat, on the rocks, or in cocktails such as the classic Old Fashioned or the Whiskey Sour.

Tasting notes for bourbon can vary depending on the specific brand and age of the whiskey, but here are some common characteristics you might expect to find:

1. Aroma: Bourbon often has a sweet aroma with notes of caramel, vanilla, and oak. You may also detect hints of fruit, such as cherry or apple.
2. Flavor: The flavor of bourbon can be described as sweet and smooth, with a caramel or toffee-like sweetness. You may also taste notes of vanilla, oak, and sometimes cinnamon or nutmeg.
