It’s all about the beer. Enjoy!

Draught Beer
All draught beers are served between 40 and 45 degrees. We serve all our beers in 13 oz and 16oz glassware. We also serve half glasses and individual tasters in 4 oz glassware. Sample tray tasters of 4 different beers in 4 oz glassware are also available.

Kegged Beer
We sell both 1/6 and 1/2 barrel kegs. Keg deposits are required. Check with tasting room personnel on pricing and availability.

Growler Fill Policy
We serve our beer in our own growlers. We don’t serve in blank growlers or other brewery growlers. We put a lot of effort into building our beers and care a lot about how it leaves our brewery and how its presented at your final destination. Our growlers meet all federal and state labeling requirements.  This policy serves to ensure that our beer is provided to you at the highest level of quality possible.

Our tasting room sells hats, t-shirts, glassware, growlers, stickers and coasters. Feel free to inquire with the tasting room personnel for your desired merchandise item.


We enjoy sharing our beer, especially if it benefits a great cause.
We’re glad to have the opportunity to give back to the community that supports us and we plan to donate to San Diego area non-profit organizations for fundraising events. We do not donate beer to For-Profit organizations.
If you are interested in a donation from O’Sullivan Bros. Brewing Co., please contact our General Manager and he/she will follow up with you to see whether a donation is possible. We ask that all requests be submitted at least 60 days prior to the fundraiser.
Due to ABC restrictions, we can only donate beer for serving at your event if:

  • Your organization is a tax-exempt non-profit organization (with IRS approved federal tax ID #)
  • Your non-profit organization obtains a one-day event license from the ABC.
