Innstadt Brewery, Germany
The Innstadt Brewery is located on the banks of the Danube River in the Bavarian town of Passau. Opened in 1318, the brewery has always subscribed to the traditionalist brewing philosophy of Bavaria, which is something to the effect of “nothing belongs in beer except barley, hops and water.”
Visitors can tour Innstadt's facilities and also see the other historic breweries in Passau. The Hacklberg Brewery, for example, has been making beer since 1618. Beers from both these historic breweries are served at small pubs all around the town.
