At Bob's Red Mill, we know that you can't rush quality. That's why we manufacture our products using time-honored techniques, like grinding whole grains at cool temperatures with a traditional stone mill. This production 'secret' allows us to seal in the freshness and bring you wholesome, quality foods, just as nature intended. Our beautiful stone grinding mills are much like the ones used during early Roman times. And to this day, our quartz millstones remain the best way to produce the finest products available. Unlike high-speed steel rollers, our stone mills ensure the most nutritious parts of the whole grain remain, so we can pack all-natural goodness right into your bag.
