The second recipe we brewed during this season’s Ale through the Ages at Discovery World was a traditional Grätzer Ale. There was great crowd on hand to participate in this brewing session to learn about the origins of this enigmatic smoked wheat ale. Grätzer is the German name derived from the town of Grätz, formerly in western Prussia. Today this town is known as Grodzisk, located in the province of Wielkopolski in western Poland. Therefore, this style of smoked wheat ale is known as Grodziskie (Grodzisz) in Polish.
The history of brewing in Western Prussia is quite extensive. For instance, during the 15th Century in the port town of Gdansk on the Baltic Sea, the city’s output of beer was ca. 25 million liters (6.6 million gallons) (ca. 210,000 barrels). Indeed in the year 1416, 378 breweries were in operation (Unger 2004:121). The Posnań district of western Poland also has a deep brewing tradition, most notably as the birth place of Grodziskie smoked wheat ale. In 1890s Poznań (Posen) had 158 breweries, 101 of which were ale breweries producing between them 177,038 hl (148,471 Barrels) (4,676,849.2 US Gallons). The other 57 breweries were lager breweries producing 307,800 hl. (258,134 Barrels) among them. Hence, lager production accounted for 63% of the total output from Posnań, compared to 37% for ale production (Zeitschrift für das gesammte Brauwesen 1894, p.23).
In the town of Grodzisk (Grätz) alone, there were five breweries in operation in 1900. While several styles of beer were being produced in Grodzisk, the most distinct was the Grodziskie smoked wheat ale. Sadly, in 1994 the large Grodziskie Brewery closed when it was bought by local rival Lech Brewery, which ostensibly ended the commercial production of this style of beer in Poland.
According to legend, the popularity of this type of beer is associated with the Benedictine monk Bernard of Wąbrzeźno (1575-1603). After blessing a dried well in Grodzik, it eventually refilled, which allowed brewers to produce their famous Grodziskie smoked beer. Moreover, Jedrzej Kitowicz (1728-1804) wrote in A Description of Manners under Augustus III the following: “Grodzisk was famous and increasingly after the Greater Poland (mid 15th century)…(Grodziskie) is a thin and tasty beer…doctors which prohibit all alcoholic beverages to patients permit drinking Grodziskie beer.”
Traditional Grodziskie is produced by smoking wheat malt with oak or beech wood. This I had to do myself on a grill, as smoked wheat malt is difficult to obtain. I cut out the base of an aluminum foil tray and stapled metal mesh screen to the bottom, in order to allow the smoke to filter through the grain bed. After letting the wheat malt soak in water overnight, it was ready to be placed in the smoker. I used wet oak placed over a low flame to produce a heavy smoke atmosphere in which the wet grain was subjected to for a minimum of three hours.
Once the smoked wheat malt was dry it was time to grind it and get it ready for brewing. Given the large number of participants in this brewing session, we brewed 10 gallons of Grätzer. This required 20 lbs of wheat malt, 16 lbs of which was oak-smoked. The mash stabilized at 150F for 40minunts before the program began. We sparged the mash with 180F water and brought the wort to a rolling boil. Polish Marinka hops, Hallertau Mittelfruh and German Spalt hops were added throughout the boil. Once the wort was cooled one five gallon carboy was fermented with German Ale/Kolsh yeast from White Labs, while the other was fermented with German Wheat yeast from Wyeast.
Traditionally isinglass was used in Northern Europe and Britain to accelerate the clarification (fining) of cask-conditioned ales. Isinglass is a fining that is produced from sturgeon bladders, which causes the live yeast to flocculate into a jelly-like mass that settles to the bottom of the cask. For optimum performance, the beer must be fined at the coldest point in the process (ca. 50 F). This was done during during secondary fermentation, at which point the carboy was chilled outside (40-55 F).
It would be a shame for this ale to fade into the ether like so many other lost styles. Fortunately there a revival may be taking place in Grodzisk Poland. In August of 2010, a home brewing competition was held during the 31st International Breweriana Exchange called, “Almost like Grodzisz.” The goal was to recreate and revive the legendary Grodzisk beer brewing tradition, which was judged by former Grodziskie Brewery workers. Perhaps this is incentive to maintain the longevity of this very old style of ale for generations to come. Na Zdrowie!
What: Discovery World‘s Archaeologist, Kevin Cullen, is giving a talk.
Where: Marcia Coles Community Room, Lake Park, Milwaukee
When: January 23rd at 1:00 p.m.
**This event is free and open to the public.
This talk will cover Discovery World’s Distant Mirror Archaeology Program and particularly the use of cutting-edge archaeology surveying technology, namely, Ground Penetrating Radar (GPR). Deceptively simple, GPR looks like a lawnmower, but acts like a CT scanner, as it uses radar signals to create a 3D picture of buried remains. In 2008, we began our geophysical archaeology survey in Juneau Park, where we began discovering evidence of a 19th century residential neighborhood which was removed to create the park. In his talk, Kevin will showcase these discoveries and Discovery World’s plans for future explorations including possible answers to some of Lake Park’s secrets and buried history. For instance, could there be evidence of other prehistoric burial mounds? Is there evidence of an Indian village in the park? Was there a tavern located inside what became the park?
This program will be a must-see for anyone interested in history, archaeology, and love of Milwaukee’s Parks.
