Old Mill Days

at Bale Grist Mill

Step into 1846 and experience Napa Valley before vineyards—when wheat ruled the fields and the Bale Grist Mill thundered with harvest activity. Old Mill Days brings that era to life with hands-on demos, music, and family fun at one of California’s most beloved historic sites.

What to Expect

Stroll the grounds and join in traditional chores: woodworking, wheat winnowing, corn husking and shelling, butter making, apple pressing, hand sewing, and rope making. Millers run short, frequent demos inside the still-operational, water-powered grist mill, and you’ll find artisans outdoors showcasing fiber arts like wool carding, spinning, and lacemaking—set to lively old-time music. Kids can make corn husk dolls, try planing wood, wash on a washboard, sift flour, and play classic games.
