Dump Truck Summer Bock is a slight departure from Bayern Brewing´s usual celebration of Bavarian tradition. Though it is brewed using the old-fashioned decoction mash brewing method, Bayern has created another beer style totally unique in the Northwest. The recipe for this light, unfiltered, lager bock beer uses German sauermalt, organic Montana Spitz malt, Pilsener malt, plus three hoppings using Hallertauer Perle and the rare Tettnang aroma hops (both imported from Germany). Dump Truck uses a yeast strain, specially formulated in Germany, to make this beer a rare experience – like the one JÃ¼rgen KnÃ¶ller, Master Brewer and President of Bayern Brewing, had on one of our company rafting trips. He learned (first hand) that a Dump Truck is when the raft flips, depositing all contents not tied down into the raging river. He thought this would make an excellent name for this beer, invoking summer fun and the unexpected: like running a Class VI rapid.
