"Propeller" is the craft beer brand of the Westphalian brewery Bosch. Hans-Chrisitan Bosch leads the brewery in the 11th generation. "Propeller" was created in 2014 as a supplement to the classic line of the Bosch brewery. Four beers are currently in Propeller's assortment. Even though Propeller does not yet produce much output - they brew on a large scale.
So what about their "Turbo" Prop? The Imperial Pils from Propeller potentiates the beer style Pilsener. More alcohol, more hops, more of everything. Pils with turbo. From the light malt come honey notes and the full-bodied and soft mouthfeel. The German hop varieties Herkules (for the bitter) and Saphir (for the aromas) are typical for a Pils, in Turbo Prop they were supplemented with Citra - cold hopped.
