What is the minimum percentage of corn required in bourbon production?

In bourbon production, the minimum percentage of corn required is 51%. This requirement ensures that the distinct sweet flavor associated with corn is prominent in the final product. Bourbon must meet several legal definitions to be classified as such in the United States, and the grain mix (mash bill) is a fundamental aspect of its identity. Having at least 51% corn not only allows for the sweetness typical of bourbon but also differentiates it from other types of whiskey that may have different primary grains in their formulations. The emphasis on corn is significant because it plays a crucial role in the fermentation process, impacting the aroma, flavor, and overall character of the bourbon. Thus, the correct answer aligns perfectly with the legal standards governing bourbon production.
