Built in 1846, this water-powered mill served Napa Valley's farmers who brought their wheat grain and dried corn to the mill to be ground into flour and meal. Bale Grist Mill has one of the largest waterwheels in the country and still mills grain the old-fashioned way! Visitors can take home organic wheat flour, cornmeal or polenta. Come enjoy what was once a vital part of rural life!Built in 1846, this water-powered mill served Napa Valley's farmers who brought their wheat grain and dried corn to the mill to be ground into flour and meal.
