This recipe took first place at the SODZ British Beer Festival, and is fairly straightforward. It is meant to be in the style of Fuller’s London Porter (my personal favorite), with brown malt being the key flavor ingredient. It was entered in the Beer Judge Certification Program (BJCP) Brown Porter category.
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.
