Approach to Lager Brewing at Von Trappe Brewing
Von Trappe Brewing in Vermont has gained recognition for their quality lagers, winning awards at World Beer Cup and GABF. With a focus on the Austrian and European lager styles, they emphasize traditional methods like decoction boiling and a 90-minute boil to enhance flavor and control DMS. Their meticulous yeast management involves controlled over pitching and a vigilance for sulfur compounds, ensuring consistent fermentation. Lagering in cylindrical tanks for about 30 days, they balance the need for clarity with maintaining desired flavor profiles.
Innovative Brewing Practices and Quality Control
Von Trappe's meticulous approach extends to their fermentation and quality control processes. They manage yeast propagation carefully, utilizing a Bavarian yeast strain to achieve clean, unique flavors. The use of a centrifuge helps clarify beers, ensuring consistent results. With a focus on maintaining precise fermentation temperatures, yeast health, and attenuation levels, they strive for balanced and flavorful lagers.
Balancing Tradition with Innovation in Lager Crafting
While Von Trappe embraces traditional European lager styles, they also innovate with their brewing practices. By adjusting fermentation times, yeast cropping procedures, and lagering durations, they tailor each beer's profile. Their attention to detail during both the hot and cold side processes allows them to achieve a balance between classic lager characteristics and modern brewing techniques.
Developing Unique Lager Styles
The podcast discusses how Von Trapp brewery focuses on creating unique lager styles by experimenting with different brewing techniques and ingredients. They mention their Marzen-style vontrap Octoberfest beer that blends Munich malt types one and two to achieve a balanced flavor profile without excessive sweetness. The brewery aims for drinkability and lower bitterness levels, highlighting a commitment to crafting approachable and well-rounded lagers. Additionally, the team explores decoction processes in brewing, such as the use of Munich malt and the considerations behind decoction methods for various beer styles.
Focus on Quality and Process Optimization
The podcast emphasizes Von Trapp brewery's dedication to quality in their brewing process, with a particular focus on meticulous material handling and yeast management. They highlight the importance of maintaining yeast health and avoiding off-flavors through attentive brewing practices. The team discusses the impact of water quality on beer production and the significance of step chilling to preserve yeast viability. Moreover, they delve into the use of crush consistency, low diacetyl levels, and careful centrifuge handling to enhance the overall beer quality, leading to single-digit diacetyl levels in their finished products.
While popular movies tell finite stories, the real lives of the people they feature don’t stop when the final credits roll. So, it was up to the von Trapp family—whose story was told with huge dramatic license in The Sound of Music—to write their own next chapters. They did so by establishing a popular, Austrian-inspired family lodge in northern Vermont—then, about 15 years ago, they opened a brewery just down the hill.
They launched with the goal of producing finely crafted European-style lagers, befitting the family’s heritage. Craft lagers weren’t exactly lighting up the sales charts at the time, but it was a long-term bet from a family that thinks in generations rather than quarterly returns. Now, with a beautiful automated Rolec brewhouse and an attached beer hall, they’re producing award-winning lagers at scale—including the Oktoberfest that we named one of our Best 18 Beers in 2018—all while making very intentional decisions about process and ingredients.
In this episode, brewing operations director Tom Everett and quality manager Jack Van Pappegem talk through their approach to ingredients and process, including:
avoiding decoction of many pale lagers, despite having an automated and dedicated decoction vessel
finishing pale lagers dry, but not too dry
using small amounts of specialty malts to build character
managing the grain crush
keeping a tight focus on pH
strategies to promote healthy fermentations
selecting yeast for the ideal character
lagering in cylindroconical unitanks
brewing Oktoberfest lager as well as dark lagers
And more.
