After a one year hiatus, Jester King Brewery’s blackberry sour ale is returning this week.

That beer is 2019 Nocturn Chrysalis, a 6 percent ABV barrel-aged sour beer refermented with Marion blackberries sourced from Decker Farms in Hillsboro, Ore. According to a post on Jester King’s website, the base beer for the newest incarnation of the sour ale is the brewery’s Das Überkind, and it was bottled in July.

This is the sixth release of Nocturn Chrysalis after it debuted on Oct. 27, 2013. That version incorporated a sour red ale as its base and was referemented on Kiowa blackberries from Oglesby, Texas.

According to Jester King, 2017 Nocturn Chrysalis is packaged in 500ml bottles ($20) and is scheduled to be released on Aug. 16. There will be approximately 1,090 bottles available, and each person will be limited to four bottles per person per day.
