Pros of Two Roller Grain Mills. Two roller mills are substantially cheaper than three roller mills and provide adequate results for the average homebrewer. The benefits of a three roller grain mill can largely be achieved by running the grain through a two roller mill twice. This makes the price savings worthwhile for homebrewers on a budget.
