What is the milling process in the context of spirit production?

The milling process is a critical step in spirit production, particularly when working with cereal grains. It involves the grinding and separating of these grains to prepare them for fermentation. This process breaks down the grain's structure, increasing the surface area for enzymes to convert starches into fermentable sugars during the mashing stage.

By effectively milling the grains, producers can ensure a more thorough extraction of sugars, leading to higher alcohol yields during fermentation. This step is foundational for the production of various spirits, including whiskey and vodka, where the starting materials are primarily grain-based. Understanding how milling contributes to the overall process highlights its importance in the production of high-quality spirits.
