Here is a recipe for the base beer of Warsaw Baltic Porter from a recipe from the now shut-down Royal Warsaw Brewery, one of the original brewers of the Baltic Porter. The author went on to ice (lodowy) half of the fermented beer to make it a Warszawski Porter Lodowy.
Would you like a smooth-drinking porter with subtle coffee notes layered in between the roasted grain aromas? Then don’t even look at this recipe. If you like your coffee black, your porter robust and your death metal Swedish, then this your beer.
