Bourbon mashbill refers to the specific combination of grains used to produce bourbon whiskey, a distinctive American spirit known for its smooth, full-bodied flavor. By law, bourbon must be made from a mash that is at least 51% corn, with the remaining percentage typically consisting of malted barley, rye, and/or wheat.
The mashbill plays a crucial role in determining the final character of the bourbon. Different grains impart unique flavor and aroma compounds, allowing distillers to craft a wide range of expressions. High-corn mashbills tend to produce sweeter, more approachable bourbons, while higher rye content contributes spiciness and complexity. Mashbills also influence the aging process, with higher-rye bourbons often requiring longer aging to mellow their assertive flavors.
