NOTE: Founders may only purchase (1) membership for themselves and it must be tied to their current email address. Attempts at purchasing multiple memberships will result in removal from Ambassadors of Sour. 



10 Sour Beers

As an Ambassador of Sour, you will receive 10 bottles of sour beer that the blenders at The Rare Barrel will create specifically for you and the other members. Of the 10 bottles included in the membership, we anticipate that there will be two bottles each of five different brands. These beers will be blended specifically for the Ambassadors. In order to preserve quality, we do not commit to any specific releases or any release schedule. As such, your bottles may be released at any point in 2015. In the case of a slight overage in blending, The Rare Barrel plans to offer Ambassadors the opportunity to purchase additional bottles online or in person. We also plan to cellar some of these excess small-batch blends for the purpose of a vintage release at a later date or for serving at special events. Our intent is for these beers to be available just for the Ambassadors of Sour, but if we have an excess after 2015 we may offer them for special events or to the public for on-site consumption in the tasting room in 2016 and beyond.

First Right to Purchase Bottled Beer

In 2015, we plan to release other bottles that are not included in the Ambassadors of Sour membership. As an Ambassadors, you will have the first right to conveniently purchase a limited number of bottles of most bottled releases through the website ( Ambassadors will have access to purchase non-club releases online before the public has access to them in the tasting room, on our website, or other distribution channels. We may sell the draft version of a particular release before we sell the bottled version.

10% Discount 

Ambassadors of Sour will receive a 10% discount on purchases made through the Tasting Room and website. This includes bottles, draft beer, growler fills, apparel, and food. Discounts do not apply to memberships. 

Custom Growler

Ambassadors of Sour are guaranteed a custom growler that is unique to the club. When the Tasting Room is open, Ambassadors will have access to fill their growler with the “Ambassadors Fill”. The Ambassadors Fill is one beer that we designate as the club’s growler fill for that week. Only Ambassadors will be able to fill their growler with the Ambassadors Fill. We also expect to start selling glass growlers through the Tasting Room in the near future. When this begins, we plan to have two options available for growler fills. Ambassadors will have access to both growler fills, while non-club members will only have access to one of the fills. Ambassador branded growlers can be filled by anyone in possession of the growler (i.e. you can have a friend fill your Ambassador growler with the Ambassadors Fill in your absence). Empty growlers can be picked-up in the tasting room or shipped at an additional charge. We do not ship full growlers, and do not recommend shipping any growlers with beer in them. In order to control our limited supply of sour beer, we will only fill growlers branded by The Rare Barrel.

Custom Glassware

Each member will receive two pieces of glassware that are specific to the Ambassadors of Sour.  Glassware can be shipped (at additional charge) or picked-up in the tasting room.

Membership ID Card

Membership includes a personalized, non-transferrable, membership card. Members must present this card in the Tasting Room to receive the 10% discount. Founders Club members who join Ambassadors of Sour will receive a distinct membership ID card designating their Founders Club status.

First Right of Acceptance to 2016 Membership

Ambassadors of Sour will have the first right to re-enroll in the 2016 club. The number of memberships available for 2016 is currently undetermined, but will be based on production volumes and our ability to provide club members with limited release blends. Either way, each Ambassador will have the opportunity to re-enroll.

Order Shipping and Brewery Pick Up

Ambassadors will have three options for fulfilling their orders placed online. As an Ambassador of Sour, you can either pick-up beer at brewery, ship beer to their house/business in California, or a designate a trustee to pick-up their beer from the Tasting Room for them.

Brewery Pick Up | Ambassadors have the convenience of placing orders online and picking them up in the Tasting Room, at no additional charge. Orders can only be picked-up from the Tasting Room during normal Tasting Room hours. Beer purchased through the membership may be stored at The Rare Barrel until March 31st, 2016. If you do live locally and visit the Tasting Room, we ask that you please pickup your bottles and do not use our brewery as a cellaring facility. We are running out of space surprisingly fast. 

Shipping within California | Ambassadors have the opportunity to ship their beer to to any residential or business address in California at an additional cost. We currently fulfill orders once per week. When we ship beer in California, we usually ship orders on Tuesday and they usually arrive on Wednesday. Shipping costs in California for next-day delivery range from approximately $14 for one bottle to $25 for 12 bottles. If you would like to save on shipping costs, Ambassadors have the option to combine orders and ship multiple orders at once. The Rare Barrel is only legally allowed to ship to addresses within California, even if your state allows beer shipping. A signature and government issued ID proving that the person accepting the packing is 21+ years of age will be required upon delivery. We cannot ship beer to P.O. boxes. 

Trustee | Ambassadors of Sour may designate a Trustee to pick-up their beers in the Tasting Room. This is a great option if you live outside of California and are not able to visit the Tasting Room or ship your beers in California. Ambassadors may also ship their beers to their trustee (or anyone else 21 years of age or older) if he or she lives in California.  The 10% discount and other club benefits do not apply to Trustees.


Enrollment in Ambassadors of Sour is valid through December 31st, 2015. Beer purchased through the membership may be stored at The Rare Barrel until March 31st, 2016.
