Whiskey and bourbon are both types of distilled spirits, but they have some key differences when it comes to their mash bill, or the mixture of grains used in their production. As an expert sommelier and brewer, I can provide you with a detailed explanation of the differences between whiskey and bourbon mash.
To begin with, let's talk about whiskey in general. Whiskey is a broad category that includes various types such as Scotch, Irish, and American whiskey. The mash bill for whiskey can vary depending on the specific type and style being produced. However, the common factor is that whiskey is typically made from a combination of grains, which can include corn, rye, wheat, malted barley, or malted rye grain.
On the other hand, bourbon is a specific type of whiskey that has its own set of regulations and requirements. In order for a whiskey to be considered bourbon, it must meet certain criteria set forth by the U.S. government. One of the key requirements is that the mash bill must be made up of at least 51% corn. This high percentage of corn gives bourbon its distinctively sweet and rich flavor profile.
The remaining portion of the bourbon mash bill can consist of other grains such as rye, wheat, malted barley, or malted rye grain. The specific combination of grains used in the mash bill can greatly influence the flavor and character of the bourbon. For example, a higher percentage of rye in the mash bill can result in a spicier and more robust bourbon, while a higher percentage of wheat can yield a softer and smoother bourbon.
Personally, I have had the opportunity to taste and evaluate a wide range of bourbons with different mash bills. One bourbon that stands out in my memory is a small-batch bourbon that had a mash bill consisting of 70% corn, 15% rye, and 15% malted barley. This particular bourbon had a wonderful balance of sweetness from the corn, spiciness from the rye, and depth from the malted barley. It was truly a complex and enjoyable bourbon to savor.
The main difference between whiskey and bourbon mash lies in the regulations and requirements set forth for bourbon production. Bourbon must have a mash bill that is at least 51% corn, while the remaining portion can come from a variety of grains. This distinction gives bourbon its unique flavor profile and sets it apart from other types of whiskey. As a sommelier and brewer, I find the diversity of bourbon mash bills to be fascinating and believe that it contributes to the wide array of flavors and styles found within the bourbon category.
