From the Brewery:
"Hottenroth Berliner Weisse is brewed in memory of Fred & Sarah Hottenroth, our founder, Patrick Rue’s grandparents. This tart, German-style Berliner Weisse is as authentic as it gets. We use lactobacillus and a hint of brettanomyces to sour this very unusual, low gravity wheat beer. To cut the tartness for those with sweeter tastes, raspberry or woodruff syrup is a traditional way to sweeten the beer. Almost an extinct style, we hope to help revive the Berliner Weisse in memory of two great people."
