The Rare Barrel Proportional Response

The Rare Barrel Proportional Response BA Sour Amber

We are excited to announce that we are almost ready to release bottles of Proportional Response, our amber sour beer aged in oak barrels.

Proportional Response, a balanced amber sour beer, is a blend of our mouth-puckering red sour beer and our faintly tart pale sour beer. The result of this blend is a well-balanced amber sour beer with moderate tartness and hits of cherries and grapefruit.

  • Beer type: Amber Sour
  • Yeast: Brettanomyces bruxellensis
  • Bacteria: Lactobacillus delbrueckii
  • pH: 3.43
  • Bottling Date: 2/12/14
  • 4.8% ABV

Here are a few details around the bottle release of Proportional Response:

WHEN | Doors open at 2PM on Saturday, May 17th

WHERE | The Rare Barrel, 940 Parker Street, Berkeley, CA 94710

WHAT | 750mL bottles of Proportional Response, our amber sour beer aged in oak barrels. Each bottle is priced at $20. There is a limit of (2) bottles per person for the first 100 visitors, and (1) bottle per person after that. Click here for more details about Proportional Response.

HOW | While supplies last, we will give each person a wristband that reserves them the ability to purchase 1 or 2 bottles of Proportional Response on Saturday, May 17th. The first 100 customers will have the option to purchase up to (2) bottles, and the remaining visitors will have the option to purchase (1) bottle. We had a similar number of bottles available at our last release, and ran out of wrist bands ~15 minutes after opening. Once you have a wrist band, you no longer need to wait in line, and may go to the bar and relax until the line for bottle purchases dwindles down. We will also have more people staffed at the bar this time around, so bar service should be faster this time around.
