Mashing is a fundamental process in making spirits where grain or other starchy materials are mixed with hot water to create a sugar-rich liquid that will later become alcohol. It's similar to making oatmeal or brewing coffee, but on an industrial scale. This process breaks down starches into fermentable sugars, which is essential for producing whiskey, bourbon, and other grain-based spirits. When you see this term in resumes, it refers to someone's experience with this crucial first step in spirits production.
