Why should you have your own grain mill? Because the oils in your brewing grains will start to oxidize as soon as they are crushed, so the freshest grain is the grain you crush yourself. These stainless steel malt mills will make quick work of your grain bill, crushing your grains to your ideal level of crush. A grain mill is an ideal addition to your brewhouse if you're looking to store grain at home, or if you plan on doing a large number of all-grain brews.
