The focus during last weekend’s Franciscan Well October Beerfest was very much on premium beers from abroad. There were about two dozen excellent imported beers on tap and some of these were part of the core theme of Sour. But their own beers were not forgotten about either and there were a couple of tasting sessions in the upstairs bar to highlight these.
At the boiling stage, hops are added to the wort for bitterness, hops added later for aroma. The wort is now pumped through a heat exchanger to the fermentation tanks. Yeast is added to convert the sugars into alcohol. When this process is finished, the beer is ready for conditioning and filtering and finally packaging. I don’t think the Franciscan Well video is online but there is a reasonably similar English brewery one here.
