Grain Mills give you the option to crush only the amount of grain you care to process for your brewing day and nothing more. A grain mill allows you to keep your shelf life of whole grain much longer and once crushed you should really use your grist in 1-2 days. Hop Goblin has a variety of grain mills for your needs and price budgets. Some grain mills have hardened rollers and knurled steel rollers for longer life and use. Knurled rollers help to efficiently pull the grain through the rollers while leaving
the hull intact to form an excellent filter bed for sparging. Enjoy the selection and choose the one that fits your needs for high quality and fresh brews of your design. Moist or wet grains (especially corn) can gum up your knurled rollers - so you should avoid this as much as possible.
