Napa Fermentation Supplies

In 1983, we opened the doors in a small building, carrying only the bare essentials for fermentation. Since then, the community has helped us turn a family's dream into a major resource for wineries along with home winemakers and brewers. The business has grown to a 7,000 sq. ft. building and offers everything for the wine industry, supplies for home wine-making and home brewing as well as monthly beer brewing classes. In addition, we sell Karcher pressure washers and employ a full time Karcher technician.  Napa Fermentation is located just inside the Expo grounds, and open to the public 6 days a week.

Normal Business hours are:

  • Monday through Friday, 9:00 am to 5:00 pm, and
  • Saturdays from 10:00 am to 5:00 pm.

Give Pat and Colleen a call for all of your home wine making and beer brewing needs!
