Back in February of this year, we added several hundred pounds of raspberries to oak barrels containing mature sour beer. We then allowed the beer to re-ferment to dryness. The result is Atrial Rubicite, our first barrel aged sour beer to incorporate fruit. Atrial Rubicite is made from well water, barley, wheat, hops, farmhouse yeast, native yeast from the Texas Hill Country, souring bacteria, and raspberries. It’s 5.8% alcohol by volume, has a finishing gravity of 1.005 and is 3.36 pH. It is unfiltered, unpasteurized and 100% bottle conditioned. Atrial Rubicite is our first beer to be packaged exclusively in 500 ml bottles.
