The Pros and Cons of a Two vs Three Roller Grain Mill for Homebrewing

Throughout the course of your homebrewing career, you may find that you pass through several phases of brewing process, complexity, and equipment. As batch sizes and brewing process complexity increases, homebrewers start to need to purchase new equipment. While you can usually purchase your grains pre-milled by your local homebrew supply shop or an online homebrew supply store like MoreBeer, a grain mill is a solid investment for an advanced homebrewer who wants more control over their grain bills, grain crush, and brewing schedule. Before you can pick a specific model, you will have to decide on whether you want to purchase a two vs three roller grain mill.

There are a ton of great grain mills on the market (click here to check out our guide to the best grain mills for homebrewing), and one of the biggest differences between the various available grain mills is the number of rollers. Most homebrewing-level grain mills have either two or three rollers. Most three roller mills first pull the grain through a fixed-width gap that helps to separate the hull intact before pulling the grain through the adjustable gap to crush it. This helps keep a good bed of hulls in your grist which filters the mash and helps avoid stuck mashes and stuck sparges.

Two and three roller mills each have their own pros and cons that should be considered when deciding which is the right grain mill for you. Need some help deciding? Here is an overview of the pros and cons of a two vs three roller grain mill for homebrewing!

What is the better choice between a two vs three roller grain mill?

Ultimately, three roller grain mills are easier to use and are more efficient than two roller grain mills. However, the additional cost may not be worth it for the average homebrewer. We use a three roller grain mill here at BrewTogether HQ and have been very happy with it, but there are some great two roller options that would work just as well.
