Evolution is a 2500 barrel per year capacity brewery and quickly expanding. Whole kernal grain (generally barley) is milled (milling), then mixed with hot water in a vessel called the mash tun (mashing) The resulting liquid (wort) is run off into the brew kettle (lautering) When the kettle is full it is brought to a boil and boiled for 1.25-1.5 hrs. Hops are added at various stages of the boil to develop bitterness, hop flavor and aroma. At the end of boil the wort is cooled and pumped into a fermenting tank. Yeast is added. Fermentation takes place in the fermenter over the next 5-7 days. At this time the beer is cooled and dryhopped if necessary. The beer is further conditioned for 7-14 days, then filtered, carbonated and packaged in kegs or bottle
