Mash Bill
A mash bill is like a recipe that shows what grains are used to make whiskey or bourbon. Think of it as the ingredient list that distillers use - it might include corn, rye, wheat, or barley in different percentages. This term is very important in distillery work because the mash bill directly affects how the final product tastes and what type of spirit it becomes. For example, bourbon must have at least 51% corn in its mash bill by law. When you see this term in resumes or job descriptions, it shows that the person understands one of the most fundamental aspects of spirit making.
