Keystone Farm is a small grazing dairy on County Road 37 in Buffalo, Minnesota, milking a mixed herd of Jersey, Fleckvieh, Norwegian Red, Brown Swiss and Dexter cows.
The farm documents its daily life on its YouTube channel, from mob grazing the milk cows and managing silvopasture to keeping hogs and hens, with new videos posted most weeks through summer 2026.
According to its listing in the Weston A Price Foundation's Real Milk directory, the cows are grass fed only with no grain, just a small amount of alfalfa pellets at milking, the pastures are rotated often and managed beyond regenerative, and the farm milks once a day and practices calf sharing. Raw milk is sold from the farm at 12 dollars a gallon and 6 dollars a half gallon. There is no website, so contact is by phone.
