Becoming a Member

We invite you to consider joining our co-op as a member and co-owner. As California's first co-op brewery, we share the common objective of working together to offer high-quality beers and create a first-class experience for our members and customers. We've already brewed many beers, our beers have won awards, local businesses are serving our beer, and every sale and success brings us closer to the possibility of opening the doors of our own taproom or brewpub.

Member Participation

All co-op members are, in fact, member-owners of an ongoing business. As a cooperatively owned, staffed, and self-managed organization, all members are expected to participate in the planning and running of our brewery. Here are some opportunities to help run the co-op, meet fellow members, and learn about what we're doing:

  • Attend one of our many existing events (listed on Meetup)
  • Propose new ideas for events
  • Join one of the co-op's committees or working groups
  • Help select the beers that we brew
  • Help create a beer recipe
  • Serve on the board of directors

Member Benefits

Here are some benefits that our co-op members already enjoy:

  • Wholesale pricing on our beer
  • Special events, including keg-tappings and barbecues
  • Discounts on merchandise (T-shirts, pint glasses, keychains, etc.)
  • Explore new beers that you never even knew existed
  • And perhaps most importantly, bragging rights about owning a brewery

Joint Membership

One membership in our co-op can be for either an individual or a couple, so long as you both live at the same home address. While you will both be members, there is only one vote per membership. If you'd both like to have your own vote, you could both sign up as individual members. To add a joint member please send an email with your name and the name of the joint member living at the same home address to:
