Jester King Brewery has announced a variation of one of its most popular beers.

The Austin, Texas-based brewery’s newest beer is Sherry Barrel Atrial Rubicite, which as the name suggests, the base beer is the fourth batch of Atrial Rubicite, a 7 percent ABV sour beer refermented on raspberries and aged in a single 500l Spanish sherry barrel for 15 months.

A post on Jester King’s website explains the brewing process:

The base beer for Sherry Barrel Atrial Rubicite was brewed in 2013. After maturing in oak barrels for about a year, it was blended during the spring of 2014 and refermented with raspberries. It was then racked to a single 500 liter Spanish sherry barrel for further aging and maturation. In July of 2015, fifteen months later, we racked the beer out of the sherry barrel and bottled it. All together, Sherry Barrel Atrial Rubicite took a little over two years to make. Again, this isn’t to suggest that long periods of fermentation and maturation necessarily equate to enjoyable beer, but in this case, we think it does.

According to Jester King, Sherry Barrel Atrial Rubicite will be packaged in 330ml bottles ($12), the first time the brewery has used this size bottle.
