Created by Dr. Fritz Briem of Doemens Institute, brewed by Weihenstephan & Doemens, ââ¬Å1809ââ¬Â is a very traditional interpretation of the ââ¬ÅBerliner Styleââ¬Â Weisse with an intense blend of lactic tartness and complex fruitiness. It is bottle-conditioned, unfiltered and unpasteurized. "1809" will age beautifully in a dark and cool location. Its complex fruitiness and tartness will most likely develop in quite astonishing ways. ââ¬Å1809ââ¬Â is fermented in traditional open fermenters and horizontal lager tanks. The applied mashing regime is a single step decoction mash with 50 % wheat malt.The total amount of hops is added to the mash so that isomerisation takes place in the decocotion part of the mash. The wort is not boiled but only heated up to boiling temperature and then transferred to the open fermenters and pitched with yeast and lactic acid bacteria (isolated from malt) at 18 ðC (64ðF).
