This is Josh Weikert’s recipe for Ostseekuste Porter (what the Germans call the Baltic Sea coast in northern Germany!), a Baltic Porter that has been a consistent winner for him over the years. It sets up well as a kettle sour, though, because the bright lactic acidity will pair very nicely with the dark fruit and chocolate flavors.
