Doppelbock traces its history to a monastic brewery founded in 1634 in the Bavarian town of Munich. To sustain them during periods of religious fasting such as Lent and Advent, the Pauline monks drank a dark, sweet beer called Sankt Vater Bier or Holy Father Beer. If eating and drinking nothing but doppelbock for four weeks sounds like a good idea to you, perhaps you should consider the original composition of this dark brew (not to mention professional help). The original doppelbock was low in alcohol at about 4 percent by weight and high in residual sugar. The final gravity around 1.035 made it extremely sweet. The high sugar content in this 16th century brew, similar to today’s Ovaltine, undoubtedly provided fasting monks the nutrients they needed to survive the ordeal of food deprivation. In 1780 the monks made their unique beer available to thesecular public. Beer drinkers likened the brew to the cherished pale bock fromthe north German town of Einbeck. Because of the strength of the brew and itsdark color, it was dubbed “doppelbock” or “double bock.” During the reign ofNapoleon in the early 1900s, all the breweries of Germany were secularized. ThePaulaner brewery came under the ownership of Franz-Xaver Zacherl, who producedthe doppelbock under the name Salvator, meaning savior. Other brewers ofdoppelbock follow in the footsteps of the original by naming their beers withthe suffix -ator. Besides Salvator, the aspiring beer hunter can usually trackdown other German classics such as Ayinger Celebrator and Spaten Optimator. Nolonger designed as a diet supplement, modern versions of doppelbock have a muchhigher alcohol content, ranging in strength from 5.5 to 6.3 percent by weight.Comparatively less sweet than their ancestor, most brews ferment from anoriginal gravity of 1.072 to 1.080 down to a terminal measurement between 1.016and 1.028. The color of doppelbock varies between amber and an almost opaquedark brown, with an SRM (color) value of 12 to 30. A subtle hop bitterness, between 17 and 27 IBU, balances thesweetness while a purposeful absence of hop aroma allows the malt to dominate.Noble German hops are the traditional choice for bittering, although othervarieties will do the job. The doppelbock brewer’s goal is to make a deceptivelydrinkable beer while maintaining a luxurious mouthfeel and an intriguingaromatic complexity. So brewers use a plethora of specialty grains. The grainbill may contain 30 to 80 percent Munich malt, 11 to 60 percent pale malt, 0 to5 percent light crystal, 5 to 8 percent dark crystal, and up to 1 percentchocolate malt. Any black malts should only contribute a slight roastedcharacter that melds into the overall maltiness from the Munich and crystalmalts. A triple decoction mash, the traditional method, willcontribute color and flavor to the brew. Infusion mashers can make up anyflavor deficiencies by adding a little extra dark crystal malt and still make adoppelbock that tastes authentic. A higher conversion temperature, 153° to 155° F, will raise the finalgravity, thereby increasing the residual sweetness. Ferment cool, 45° to 50° F, with a German lager yeast.Because doppelbock has a high initial gravity, the yeast have a big job tocomplete during the fermentation. Aerating the wort thoroughly and using alarge pitching rate will ensure a complete fermentation and minimizeoff-flavors that do not suit the style. Brew your doppelbock well ahead of timeso it can lager in the fridge for at least a month.
