Sixpoint Scientists #19: Finnish Sahti

This style is the oldest known continuously brewed style in the world, dating back at least a thousand years. Sahti barrels were found on sunken Viking ships dating to the 9th century. In keeping with tradition, we went with old school yeast, employing a Belgian Lambic strain that may have been much like what was floating around in the 1500s when Sahti was spontaneously fermented. We used rye in the mash, as in ancient times, adding body and earthy notes, and juniper berries in the mash for bittering, instead of any late addition hops to recreate the flavor profile of this ancient ale. The result is a mix of sour and sweet, with a big, extra-full golden body.
