That this beer was made by Russian River for Bottleworks is not really news to most. However, a sneak peak at the label is certainly fun (found on TTB). Combining a few Russian River barrel-aged beers, PH1, Orphan Ale, Sonambic and conditioned in the bottle with Brett (these have been bottled for some time), you can rest assured this beers going to be sour - in that 'oh, so good' way.
Look for this to be available in April. And no, don't expect it to last very long on the shelf.
