Mash Tun

Term from Spirits Production industry explained for recruiters

A mash tun is a key piece of equipment used in distilleries and breweries to make alcoholic beverages. It's like a large cooking pot or vessel where grains (such as barley, corn, or rye) are mixed with hot water to create a substance called mash. This process releases sugars from the grains, which is essential for making spirits or beer. Think of it like steeping tea, but on a much larger scale with grains instead of tea leaves. The resulting liquid will later be fermented and distilled into spirits like whiskey, bourbon, or other alcoholic beverages.
