According to a label with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Upslope Brewing Co. is working on releasing Lee Hill Series Volume 28: Dry-Hopped Golden Sour Ale With Yuzu Zest, a 6.2 percent ABV sour ale aged in foeders.

The ale was then conditioned on yuzu zest before being dry-hopped with Strata hops sourced from Crosby Hops and is scheduled to be packaged in 19.2-ounce cans on April 23, 2021.

As the name indicates, the new beer is the latest release in the Boulder, Colo. brewery’s Lee Hill Series, which commemorates the original brewery location at Lee Hill in Boulder which is now used to produce small batch releases.

An email sent to the brewery for additional information was not immediately returned.
