A whiskey grain bill is a recipe that specifies the proportions of different grains used to make whiskey. The most common grains used in whiskey production are corn, rye, wheat, and barley. The grain bill will determine the flavor, aroma, and body of the whiskey.
The importance of a whiskey grain bill cannot be overstated. It is the foundation of the whiskey-making process and will have a major impact on the final product. A well-crafted grain bill will produce a whiskey that is balanced, flavorful, and complex. Conversely, a poorly crafted grain bill can produce a whiskey that is harsh, unbalanced, and unpalatable.
