Baltic porter is a version of imperial stout that originated in the Baltic region in the 19th century. Imperial stouts exported from Britain in the 18th century were popular in the countries around the Baltic Sea, and were recreated locally using local ingredients and brewing traditions. Early versions were warm fermented until the late 19th century, when many breweries began to brew their porter with cool fermentation, so are technically lagers. Baltic porters typically have a minimum gravity of 18° plato and a high alcohol content, even over 10% ABV.

Elder Pine Brewing & Blending will celebrate this event with the release of its Barrel-aged Praamzius, Ruler of Time BA Baltic Porter, 10.5% ABV.
