(Austin, TX) – The latest update from Jester King Craft Brewery, courtesy of a Wednesday email blast…
We’re excited to announce our latest beer – Atrial Rubicite. 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. The label art by Josh Cockrell is pictured below.
As of now, there’s been no release date set. We’re hoping that Texas law will soon change to make it legal for us to have an official release at our brewery. If the law changes, we’ll schedule a brewery release sometime soon.
As we mentioned, Atrial Rubicite is our first barrel aged sour beer to incorporate fruit. It won’t be the last. We love taking fruit that is highly aromatic and flavorful and fermenting it to dryness, so that the beer is imbued with the rich character of the fruit but is devoid of sweetness. With time we plan on developing a robust program of barrel aged sour beer with fruit. Eventually, we also hope to re-ferment our 100% spontaneous coolship beer with fruit.
