4 Exclusive Ambassador of Sour Blends

As an Ambassador of Sour, you will receive exclusive sour blends that the blenders at The Rare Barrel will create just for you and the other club members. We anticipate that there will be 4 different blends, of which you will receive (2) 750mL bottles or the equivalent volume in smaller format bottles. We have a lot of fun making these special beers just for you, but don't take this responsibility lightly. In order to preserve quality and make the best beers we can for you, we can’t commit to any specific release schedule. As such, your bottles may be released at any point in 2019. In the case of a slight overage in blending, The Rare Barrel may offer Ambassadors the opportunity to purchase the limited, additional bottles online. Access to additional bottles is not guaranteed and they may sell out.  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 2019 we may offer them for special events or to the public for on-site consumption in the Tasting Room in 2020 and beyond.

Exclusive Online Access to Limited Releases

In addition to the Ambassador beers included with your membership, The Rare Barrel will produce various limited release beers throughout the year. We love these experimental and small batch blends. While these beers are not included in your membership, as an Ambassador, you will have exclusive access to purchase these beers online. Some of these beers may be limited releases of past favorites and others will be experimental and may only be 1 or 2 oak barrels in size. In some cases there will not be enough bottles for every member. As a result, membership does not guarantee bottles. Limited releases are sold on a first come, first served basis and will often sell out.  
Our intent is for most of these beers to be available exclusively for Ambassadors of Sour, however if bottles remain after the AOS online sale, we reserve the right to sell excess bottles to the public. We may also reserve a small amount to be served at special events or in the Tasting Room & Kitchen for on-site consumption.

Ability to Purchase Most Public Releases Online

In 2019, we plan to release other bottles that are not included in the Ambassadors of Sour membership. As an Ambassador, you will have the first right to conveniently purchase most public bottle releases through the Ambassador Online Pre-sale on our website, before they go on sale in the Tasting Room & Kitchen. Most bottles purchased through this method can be stored at The Rare Barrel until July 31, 2019 or January 31, 2020. Please note that while all Ambassadors will have access to these online pre-sales, some of these beers may be limited in quantity. All bottles are sold on a first come basis and may sell out.

Ability to Store Club Beers and Most Online Bottle Purchases at The Rare Barrel

You and other members can conveniently store your club beers (bottles included with membership) and bottles purchased through Ambassador Online Pre-sales at the brewery. Bottles released and purchased online from January to June of 2019 may be stored at The Rare Barrel until July 31st, 2019. Bottles released and purchased online from July to December of 2019 may be stored at The Rare Barrel until January 31st, 2020.

Order Shipping and Pick-up

You’ll have three options for fulfilling your beer orders placed online: pick-up at the brewery, ship to your house/business in California, or designate a trustee to pick-up from the Tasting Room & Kitchen for you.
  • Pick-up at brewery – Ambassadors have the convenience of placing Ambassador Online Pre-sale orders online and picking them up in the Tasting Room & Kitchen during normal hours, at no additional charge. All Ambassador Online Pre-sale beer purchased through the membership may be stored at The Rare Barrel until the designated cut off time.
  • Shipping within California – Ambassadors have the opportunity to ship their beer to any residential or business address in California at an additional cost. When we ship beer in California, we usually ship orders on Monday and Thursday and they usually arrive the following day. Shipping costs in California for next-day delivery currently range from $15 for 1-3 bottles, $18 for 4-6 bottles, $21 for 7-9 bottles, and $24 for 10-12 bottles. If you would like to save on shipping costs, we make it easy for you to combine multiple orders to ship at once. While we do have Ambassador Second Chance Sales and will periodically open online sales to the public, only the Ambassador Online Pre-sale orders can be combined and shipped at a later date.  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 beer 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. The 10% discount and other club benefits do not apply to Trustees.

10% Discount 

You and other Ambassadors will receive a 10% discount on all beer, merchandise, events, and food purchases made through the website and Tasting Room. We hope you enjoy that! The discount does not apply to membership renewal or purchases made by your trustee.

Ability to Purchase Exclusive Merchandise

As an Ambassador, you will have access to the Ambassador online store where you will find merchandise exclusive to Ambassadors of Sour. We will carry our classic merchandise items like our hoodie, white vacuum insulated growler and unique glassware, as well as limited one time items throughout the year. Lookin’ fly.

Ambassador Exclusive Growler Fills

As an Ambassador, you will have access to exclusive growler fill options when visiting our Tasting Room & Kitchen. An Ambassadors of Sour branded growler is required for growler fills. If you do not already have one and you are interested in growler fills, you can purchase a growler in the Tasting Room & Kitchen as well as the Ambassadors of Sour online store.

Membership ID Card

Membership includes a personalized, non-transferable, membership card. Your discount will automatically be applied to online orders, but we ask you to present this card in the Tasting Room & Kitchen to receive the 10% discount when you come visit.

First Right of Acceptance for 2020 Membership

If you enjoy 2019 with us, we’d love to have you back. Ambassadors of Sour will have the first right to re-enroll in the 2020 club. The number of memberships available for 2020 is currently undetermined, but will be based on production volumes and our ability to provide club members with limited release blends.

Loyalty Beer (additional benefit for Ambassadors with 5 or more consecutive years in the club)

The Rare Barrel blenders will create, bottle, and gift a beer exclusively for those of you Ambassadors of Sour who have been a member for at least 5 consecutive years.  This blend will be a gift that is included as part of your membership at no additional cost. We expect to have 1,500mL of this special beer to give each of you who have been with us for the last 5 years!


We will throw various events throughout the year, and Ambassadors may get early notice or priority to tickets for some events, but membership does not guarantee access to events.


Enrollment in Ambassadors of Sour is valid through December 31st, 2019. Any beer or club goods that are not picked up by the picked up by the deadlines will be forfeited.

Termination of Membership

Each person is allowed to have a maximum of one membership. If a member is found to have multiple memberships, we reserve the right to cancel and refund the unused portion of all of that person’s memberships.
All beer purchased and obtained through your Ambassadors of Sour membership is for the purpose of consumption. Drink the beer, enjoy the beer, or trade it with your friends. However, please do not resell our beer without obtaining a wholesale account with us. Licensed retailers and wholesalers are prohibited from purchasing beer as an Ambassador of Sour unless it is solely for personal consumption and not for resale or distribution. If a club member is found illegally reselling our beer, their membership will be canceled.
