Mashbill

In bourbon production, the mashbill typically consists of at least 51% corn, as required by law, with the remaining portion usually made up of rye, barley, and sometimes wheat. A traditional bourbon mashbill might include around 70-75% corn, 10-15% rye, and 10-15% malted barley, resulting in a rich, sweet flavor with hints of spice. When wheat is used instead of rye, as in a wheated bourbon, the whiskey tends to be softer and smoother, with a sweeter profile.

For rye whiskey, the mashbill must contain at least 51% rye, which imparts a bold, spicy, and peppery character to the spirit. Other grains like corn and barley are added to balance the flavors. The mashbill plays a crucial role in shaping the taste, aroma, and texture of the final product, making it a fundamental aspect of whiskey-making craftsmanship and tradition. Each distillery often guards its mashbill recipe closely, as it is key to creating distinctive and signature whiskey expressions.
