Old Ox is a family owned and operated commercial brewery. Old Ox is one of the oldest roads in Loudoun County and was originally built to connect the agricultural producers of Loudoun County to the markets in Fairfax County and beyond. It is this same sense of connection that we want to provide for our customers…whether they are here in our tasting room or enjoying a pint in their favorite restaurant or tavern. We brew in a 30-barrel brewhouse. Just to give you some perspective, each batch we brew will produce 930 gallons of beer. That is enough for 9,920 12-oz. cans of beer or a little over 413 cases of beer per batch.
