Welcome to the Dr. Hans Brewery community! In the video above, Dr. Hans shared a fascinating discovery from his kegerator: an aged bottle of Nils Wallin’s “Werewolf Blood Beer,” a unique take on the traditional German Altbier. This style, though less common than some other German counterparts, offers a truly rewarding brewing experience for enthusiasts.
For many homebrewers, venturing into German beer styles can seem daunting, yet the Altbier stands as a testament to rich brewing history and accessible complexity. This distinctive German ale, hailing originally from Köln but now predominantly associated with Düsseldorf, provides a wonderful canvas for exploring malt-forward profiles with a clean, crisp finish.
Understanding the German Altbier Tradition
The term “Altbier” literally translates to “old beer,” reflecting its historical brewing methods. Before the widespread adoption of lager yeasts and refrigeration, ales were the standard. Altbier represents a preservation of this older brewing tradition, brewed with top-fermenting ale yeast at cooler temperatures, mimicking some characteristics of lagers without actually being one. This unique approach provides an intriguing balance.
Historically, the region around the Rhine River, particularly Düsseldorf, cultivated this style. Altbiers are known for their clean, malt-accentuated flavor profiles, often appearing amber to dark brown in color. They are typically well-attenuated, meaning most of the sugar is fermented out, leading to a drier finish than many other ales. Imagine a sophisticated, slightly malty English ale, but with a distinctly German crispness.
Altbier Versus Kölsch: A Tale of Two Cities
Dr. Hans correctly pointed out the shared history between Altbier and Kölsch, both originating from the same German region. While Altbier is linked to Düsseldorf, Kölsch is the iconic brew of Köln (Cologne). The comparison between these two styles often causes confusion, but understanding their differences enriches your appreciation for German brewing.
Kölsch, a pale, crisp, and delicate ale, typically presents a lighter body and a more subtle fruitiness. It’s often compared to a very clean lager due to its delicate hop character and refreshing finish. In contrast, Altbier generally boasts a richer, more robust malt character, with a deeper color and a firmer bitterness. Think of Kölsch as a bright, sparkling spring water and Altbier as a deeper, more complex river flowing through a forested valley. Both are refreshing, but their depths and characters diverge significantly.
Crafting Your Own Altbier: The “Werewolf Blood Beer” Recipe
Recreating a delicious Altbier at home requires careful attention to ingredient selection, particularly the malt bill. Dr. Hans shared the recipe for the “Werewolf Blood Beer,” providing an excellent starting point for any aspiring Altbier brewer. This recipe thoughtfully combines several malt types to build a layered flavor foundation.
The Malt Bill: Building the Foundation
The heart of any Altbier lies in its malt profile. Nils Wallin’s recipe uses a compelling combination of malts that contribute to both color and flavor, achieving that signature Altbier character. Understanding each component helps in appreciating the overall design.
-
3.25 kg Pale Ale Malt (82%): This forms the backbone of the beer. Pale Ale malt provides a clean, neutral base, allowing other specialty malts to shine through. Its high percentage ensures fermentability while supporting a balanced malt presence.
-
200 g German Cara Aroma (5%): Cara Aroma malt adds a beautiful depth of color, moving the beer towards an amber hue. Flavor-wise, it contributes notes of caramel, toast, and dried fruit, enhancing the beer’s complexity without becoming overly sweet. It’s like adding a touch of rich, dark honey to your brew.
-
250 g German Cara Red (6.3%): As its name suggests, Cara Red further intensifies the beer’s red-amber color. On the palate, it delivers more pronounced caramel and toffee notes, lending a pleasing richness. This malt truly helps define the Altbier’s visual appeal and sweet malty depth.
-
250 g Canadian Honey Malt (6.3%): Honey Malt is a unique specialty malt known for imparting distinctive honey, bready, and slightly cracker-like flavors. While not imparting actual sweetness, it enhances the perception of richness and body. This addition explains some of the delightful bready and biscuity notes Dr. Hans noted in his tasting, contributing to an English-like ester profile.
This malt combination provides a sturdy platform for the yeast and hops, creating a full-bodied beer with intriguing layers of caramel and breadiness. The high percentage of crystal malts, as noted by Dr. Hans, certainly contributes to the beer’s character and perceived richness without making it cloyingly sweet, thanks to good attenuation.
Hops and Bitterness: The German Touch
Altbiers are not typically hop-forward in the same way an IPA might be. Instead, the hops provide a balancing bitterness and subtle aromatic nuances that complement the malt. The “Werewolf Blood Beer” recipe utilizes Styrian Goldings hops, a choice that aligns well with the style’s heritage despite being a Slovenian hop varietal.
-
10 g Styrian Goldings at 30 minutes: This addition provides the necessary bitterness to balance the malt sweetness. Adding hops partway through the boil extracts bitter compounds efficiently, ensuring the beer isn’t overly sweet. Think of it as seasoning a dish; just enough to make other flavors pop.
-
45 g Styrian Goldings steep at 75°C for 30 minutes: Steeping hops at cooler temperatures after the boil (a “whirlpool” or “hop stand”) extracts more aroma and flavor compounds than bitterness. This technique adds a delicate layer of hop character without harshness. Styrian Goldings are known for their mild, earthy, and slightly spicy notes, which would subtly influence the Altbier’s profile.
-
45 g Styrian Goldings dry hop for 5 days: Dry hopping involves adding hops directly to the fermenter after primary fermentation. This method primarily contributes hop aroma, giving the beer a fresh, enticing scent. Although Dr. Hans mentioned the aroma had faded due to aging, in a fresh beer, this would provide a pleasant earthy or floral bouquet.
The hop schedule for this Altbier recipe is designed to offer a balanced bitterness and a refined hop aroma, letting the malt character lead the way. Styrian Goldings, often associated with English and European ales, bring an appropriate classic touch.
Yeast and Fermentation: The English Connection
The choice of yeast is crucial for defining an Altbier. Nils Wallin opted for WLP007 Dry English Ale yeast, which might seem counterintuitive for a German style, but it plays a significant role in achieving the desired profile.
WLP007 is known for producing clean, crisp beers with a slightly fruity ester profile, reminiscent of classic English ales. It also tends to flocculate well, meaning the yeast settles out effectively, contributing to the beer’s clarity. Dr. Hans’s observation of “English-like esters” and a “buttery cookie” note from the aged beer perfectly aligns with the characteristics of this yeast. While traditional German Altbier yeasts exist, an English ale strain can effectively replicate the clean yet slightly estery profile expected from the style, especially when fermented at cooler ale temperatures.
The fermentation numbers provided – Original Gravity (OG) of 1.056 and Final Gravity (FG) of 1.010 – indicate a significant attenuation. This means most of the sugars were converted into alcohol, resulting in an Alcohol By Volume (ABV) of 6%. This higher attenuation, despite the substantial crystal malt bill, prevents the beer from being overly sweet, contributing to its refreshing and easy-drinking nature, as Dr. Hans highlighted.
Brewing Tips for Your All-Grain Altbier
Embarking on an all-grain brew for an Altbier recipe can be a rewarding experience. Here are some beginner-friendly tips to ensure your brewing day goes smoothly:
-
Mashing: Aim for a mash temperature around 66-68°C (151-154°F) for about 60 minutes. This temperature range helps create a balanced wort that ferments well, providing both body and fermentability. A good mash ensures efficient sugar extraction from your grains.
-
Fermentation Temperature Control: For Altbier, fermenting at cooler ale temperatures (around 16-18°C or 60-64°F) is key. This cooler fermentation minimizes overly fruity esters, allowing the malt and subtle yeast character to shine through, contributing to the Altbier’s characteristic crispness. Consistency in temperature is like gently guiding a river; it keeps everything flowing smoothly.
-
Clarity: Altbiers are traditionally known for their clarity. Beyond yeast choice and proper fermentation, consider using fining agents like Irish moss in the boil or cold crashing your beer before packaging. This extra step can significantly improve the beer’s visual appeal, making it sparkle like a clean mountain stream.
-
Bottle Conditioning: Dr. Hans mentioned the “Werewolf Blood Beer” was bottle conditioned. This natural carbonation method involves adding a small amount of priming sugar to the beer before bottling. The remaining yeast consumes this sugar, producing CO2 that dissolves into the beer. This process can also contribute to a smoother mouthfeel and longer shelf life. Patience is a virtue here, as bottle conditioning typically takes 2-3 weeks at room temperature.
Brewing an Altbier offers a fantastic opportunity to explore the intricacies of malt-forward German ales. While the aging process for Nils’s beer had mellowed some of its original characteristics, Dr. Hans’s tasting notes still highlighted the beer’s good structure, refreshing qualities, and subtle English-like esters. This recipe is a solid foundation, allowing you to create your own delicious German Altbier, perhaps even tweaking it to suit your personal preferences.
