Iowa Beer, German Tradition |
Fermentation |
Now this is where the magic happens! Simply put, the yeast turn the sugar to alcohol. But the yeast are living organisms so there is nothing simple about it. They produce thousands of compounds which affect the flavor of the beer. As such there are countless strains, all with their own flavor profiles. However they can broadly be separated into Ale and Lager yeast. The English brew ales, the Germans brew both ales and lagers. |
Lagers - These yeast ferment at lower temperatures and thus slower. This tends to give the flavors more time to mature and smoothen out. US macro breweries have taken advantage of this to smooth out their already extremely light beers. However there is no reason a lager can't be full flavored, the way they were originally intended. Ales - These yeast ferment warmer and faster and produce stronger flavors. For this reason (combined with the ease of infusion mashing) they have been very popular among US micros. |
Einfach beer is primarily traditional German lagers. We ferment the beer slowly and allow it to lager (store cold) for over a month to achieve the best flavor maturation. During this time we also trap the CO2 produced during fermentation to naturally carbonate our beer. We believe if you are going to do something, do it right. |
