The Design Philosophy Behind Dovetail Brewing's Lager and Colabayin
Dovetail Brewing focuses on traditional methods of production, emphasizing the importance of malt and water quality. They import their own malt from a producer in Bamberg, Germany, which has world-class maltsters. They also pay close attention to their water composition, aiming to replicate the mineral composition of Pilsen water. Their brew house is designed to be flexible, allowing for various mashing techniques, including decoction and step mashing. They utilize a direct fire kettle for mayard production, which adds depth and richness to the beer. Additionally, all of their beers go through a cool ship, where the hot wort is allowed to cool and settle, enhancing flavor and aroma. Open fermentation is also a key aspect of their process, as it creates a low-stress environment for the yeast and adds complexity to their beers.
The Importance of Scrubbing Sulfur and Balancing Hop Character
Dovetail Brewery uses open fermentation, which allows for intimate contact with the beer and the ability to detect any issues. Sulfur compounds are produced during fermentation, and Dovetail focuses on scrubbing the excess sulfur to achieve the desired balance of flavors. They have refined their methods and techniques over time to control the amount of sulfur in their beers, particularly in their Helles and Vienna Lager. The scrubbing process removes excessive sulfur while retaining the desired hop character. Dovetail pays close attention to each beer's personality, adapting their approach to fermentation based on the specific yeast used and the characteristics they aim to achieve.
Embracing Smoke in Dovetail's Rock Beer
Dovetail Brewing is passionate about smoked beer and embraces a high percentage of smoked malt in their rock beer and doppelbock. Their rock beer and rock doppelbock both contain 95% smoked malt, primarily sourced from Fireman Specialty Malts. The remaining 5% consists of roast malt varieties such as Korafa 1 and Korafa 3. Furthermore, they utilize 100% smoked wheat malt for their Grätzer, a traditional Polish beer style. Dovetail's commitment to pushing the boundaries of smoke character sets their rock beer apart, with a focus on using smoked malt that complements and enhances the beer's overall profile. Additionally, they have experimented with using smoked yeast in their smoked helles to capture the essence of the style in a different way.
Importance of Schedule in Brewing
Maintaining a consistent brewing schedule is crucial for successful beer production. The speaker explains that certain beer styles, such as Half of Isan and Coles, have a predictable fermentation period of around four days. However, fermentation times can vary depending on factors such as yeast pitch, sugar content, and temperature. Open fermentation is a key aspect of traditional brewing and allows for better control and measurement of attenuation levels. Although open fermentation requires additional carbonation, the perceived benefits, including more character in the beer, outweigh the extra effort.
Skimming in Open Fermentation
The podcast highlights the importance of skimming the surface of the beer during open fermentation. This process helps remove dark brown hot polyphenols that rise to the top, which can otherwise impart harsh flavors and decrease drinkability. By skimming these polyphenols, traditional brewers achieve a fineness in bitterness and hop character, resulting in a more balanced and enjoyable beer. While initially, they skimmed the beer daily, they now only perform an initial skim and a skim on the day of racking. This adjustment not only reduces unnecessary work but also enhances the beer's flavor profile.
Chicago’s Dovetail has earned a reputation for its refined yet flavorful lagers, but the team’s dogged approach to traditional methods is less about religion and more about expression—these techniques and processes allow them to imbue their beers with attributes they want while minimizing those they want to avoid or keep in the background. Each beer they make is like a musical score—a recipe designed to hit the right notes with the orchestra of instruments they’ve assembled. Whether that’s multiple decoctions, dropping temperatures in the coolship before adding whole-cone hops to a hop-forward lager, or how often they skim the open fermentors, they’ve considered the cumulative impact of each of the intermediate notes.
In this episode, cofounder Hagen Dost, production manager Brittany Gedwill, and sales director Dan Modica outline their reverent and rigorous approach to making helles, pilsner, and Kölsch-style ale. Along the way, they also touch on:
creating slushies with aged spontaneous beer
defining parameters around “traditional methods” for lager brewing
the benefits of direct-fire decoction
coolshipping lagers with whole-cone hops for “harmony and cohesion”
the varying impacts of step mashing, single decoction, and triple decoction with thick and thin mashes
the necessity of sulfur and malt character in helles
walking the fine line in timing of Kölsch fermentation
brewing rauchbier with 95 percent smoked malt
And more.
