The wonderful Bale Grist Mill

Bale Grist Mill State Historic Park, in the northern heart of the Napa Valley, offers an authentic peek into Californians’ rural heritage.  Built in 1846 by Edward Turner Bale, this fully restored water-powered grist mill is now managed by the Napa Open Space District in partnership with the Napa Valley State Parks Association, and still grinds grain.  Visitors can watch the original set of French Buhr millstones in action when the miller grinds grain into Bale Mill flours and meals. In the late 1800s, Napa Valley farmers brought their grain to the mill where it was placed into the boot of an elevator to be mechanically transported upstairs to be cleaned and sifted by various types of equipment – a technical wonder for the Pioneers. The slow turning of the old grind stones gives the fresh meal a special quality for making cornbread, yellow bread, shortening bread and spoon bread. The mill is ADA accessible.

The Bale Grist Mill hosts multiple events throughout the year creating a unique way to enjoy the Mill and grounds. Events include a pancake breakfast in May, the Harvest Dinner in September, Old Mill Days in October and a Pioneer Christmas in December. Check back on our events page for more information.
