Grain Mills and Grain Handling Equipment

The grain mill is the key component in the preparation of malted grain prior to brewing. Milling is the process of breaking the grains’ husk and cracking the kernel to a specific, consistent ratio of flour, including medium and coarse particles. A versatile brewers’ grain mill must be adjustable to accommodate different malt varieties and brewing styles.
