Original Flag Porter has an incredible story to tell. This dark complex beer is brewed to a traditional 19th century British recipe using yeast salvaged from a vessel which sank in the English Channel in 1825. In 1988 several bottles of the long submerged brew were raised from their resting place 60 feet deep in the sea. They were in their original containers with their wood stoppers and wax seals intact. When the beer was examined under a microscope by Dr. Keith Thomas renowned brewer and microbiologist at Brewlab he incredibly found a small percentage of the yeast still living! After months of propagating this ancient yeast strain he brewed a porter using an 1850s recipe. Adhering to the practises of porter brewers of the era Dr. Thomas uses barley and hops grown without pesticides or chemical fertilizers.
