Pilsner: The Original Pale Lager

Pilsner beer, a globally cherished beverage, boasts a golden hue, a crisp taste, and an undeniably refreshing character. Its roots trace back to 19th-century Pilsen, in the Czech Republic, where German brewer Josef Groll introduced the world to the first Pilsner pale lager in 1842 at the Bürgerbrauerei, now recognized as Pilsner Urquell Brewery ¹. This innovation was a pivotal moment in brewing history, distinguished not only by its unique flavor but also by the pioneering brewing techniques involved in its creation.

The Origin Story of Pilsner Beer

The tale of Pilsner beer begins with a thirst for something better. In 1838, the citizens of Pilsen, disillusioned with the inconsistent quality of locally brewed ales, took a bold stand. They publicly disposed of 36 barrels of subpar ale, pouring it into the streets and eventually into the Radbuza River ³. This dramatic act was a cry for change, a demand for a beer worthy of their appreciation.

Driven by this desire for improvement, Pilsen’s brewers embarked on a quest for innovation. Architect Martin Stelzer was dispatched to Munich and other parts of Bavaria to study brewing practices and gather knowledge ³. He returned with plans for a state-of-the-art brewery, complete with a modern malthouse and kiln, and accompanied by Josef Groll, a Bavarian brewer with expertise in lagering techniques ³.

This pursuit of lager yeast was not unique to Pilsen. In 1834, two young journeymen, Gabriel Sedlmayr Jr. from Munich and Anton Dreher from Vienna, embarked on a similar mission. They toured Edinburgh breweries, ostensibly to learn about British brewing methods, but with a secret objective: to collect samples of Bavarian lager yeast, which was unknown in Britain at the time ⁵. Using hollowed-out walking sticks with hidden valves, they discreetly collected yeast samples from the fermenting vats, demonstrating the lengths to which brewers were willing to go to acquire this crucial ingredient.

Groll, equipped with his brewing skills and access to local ingredients, set out to create a beer that would satisfy the discerning palates of Pilsen’s citizens. He utilized the soft water from a local well, known for its low mineral content, which would allow the delicate flavors of the beer to shine ³. He chose light barley that was only partially malted, resulting in a lighter color and a crisper finish than the traditional dark lagers of the time. And he incorporated generous amounts of the aromatic Saaz hops, a noble variety renowned for its delicate aroma and balanced bitterness ³.

On October 5, 1842, the first batch of Pilsner beer was introduced to the world. Its brilliant golden color, exceptional clarity, and refreshingly light taste were a revelation ³. The timing of Pilsner’s emergence was fortuitous. The development of glass on a commercial scale meant that glassware was no longer a luxury exclusive to the wealthy ⁴. Now, people from all walks of life could admire the beer’s golden brilliance in clear glasses, further enhancing its appeal. Pilsner beer was an immediate triumph, and its fame quickly spread beyond Pilsen.

Ingredients and Brewing Process of Pilsner Beer

The essence of Pilsner beer lies in four simple ingredients: barley malt, hops, water, and yeast ⁷. However, the quality and careful selection of these ingredients are paramount in achieving the distinctive characteristics of a true Pilsner.

Barley Malt

Pilsner malt, derived from two-row barley, serves as the foundation of the beer. It undergoes a gentle kilning process, resulting in a pale color that contributes to the beer’s light golden hue and a crisp flavor that defines its refreshing character ⁷. Some brewers also incorporate small amounts of specialty malts, such as Carapils, which enhances body and head retention without significantly altering the color or flavor, or Munich malt, which adds a richer, more pronounced malt flavor and a slightly deeper golden color ⁸.

Hops

Saaz hops, a noble variety cultivated in the Czech Republic, are the quintessential choice for Pilsner beers ⁸. These hops impart a delicate and complex aroma, with hints of spice, flowers, and earthiness, along with a moderate bitterness that harmonizes with the malt’s sweetness. German Pilsners may also utilize other German noble hops, such as Hallertau, known for its floral and herbal notes, or Tettnang, which contributes a subtle spiciness ⁹.

Water

The soft water of Pilsen, with its low mineral content, played a crucial role in the development of the original Pilsner beer ⁶. Soft water enhances the beer’s overall smoothness and allows the delicate hop flavors to shine through without being masked by harsh mineral notes.

Yeast

Pilsner beers are brewed with lager yeast, a type of yeast that ferments at cooler temperatures than ale yeast ¹. Lager yeast produces a clean, crisp flavor profile, free from the fruity esters often found in ales, and contributes to the beer’s smooth, refined character.

The Brewing Process

The brewing process for Pilsner beer involves a series of carefully orchestrated steps:

1. Mashing: The malt is combined with water and heated in a process called mashing. This activates enzymes in the malt that convert starches into fermentable sugars, creating the wort, the sugary liquid that will be fermented into beer.
2. Lautering: The wort is separated from the spent grain in a process called lautering. This involves filtering the mash through a lauter tun, a vessel with a false bottom that allows the wort to pass through while retaining the grain.
3. Boiling: The wort is then boiled vigorously for an extended period, typically 60 to 90 minutes. This sterilizes the wort, evaporates unwanted volatile compounds, and allows for the addition of hops. Hops are added at different times during the boil to achieve the desired bitterness, flavor, and aroma.
4. Whirlpool: After the boil, the wort is transferred to a whirlpool, where it is spun to create a vortex. This helps to separate the hop debris and other solids from the wort.
5. Cooling: The wort is rapidly cooled to fermentation temperature, typically between 9°C and 13°C (48°F to 55°F) ¹⁰. This is crucial to prevent contamination and to prepare the wort for yeast.
6. Fermentation: The cooled wort is transferred to a fermenter, and lager yeast is added. Fermentation takes place at cool temperatures, typically for several weeks. During this time, the yeast consumes the sugars in the wort and converts them into alcohol and carbon dioxide.
7. Lagering: After primary fermentation, the beer is transferred to a lagering tank for an extended period of cold conditioning, typically several weeks or even months. Lagering allows the beer to mature, clarifies it further, and mellows out any harsh flavors, resulting in a smoother, cleaner taste ¹⁰.
8. Packaging: Finally, the finished beer is packaged into bottles, cans, or kegs, ready to be enjoyed.

History of Pilsner Urquell, the Original Pilsner Brewery

Pilsner Urquell, the birthplace of Pilsner beer, boasts a rich history spanning over 180 years. Founded in 1839 by the citizens of Pilsen, the brewery was initially known as Bürgerbrauerei, meaning “citizens’ brewery” ². The brewery was strategically built on a site with an abundant supply of soft water and sandstone foundations, ideal for constructing deep cellars for lagering beer ⁴.

In 1842, Josef Groll brewed the first batch of Pilsner Urquell, marking a pivotal moment in brewing history ⁴. The beer’s golden color and exceptional clarity, a result of using pale malt and the soft water of Pilsen, were a revelation in a world accustomed to dark, cloudy beers ⁴.

Pilsner Urquell’s popularity soared, and by the mid-19th century, it was being exported throughout Europe and even to the United States ⁴. The brewery’s success led to numerous imitations, but Pilsner Urquell remained the original and most celebrated Pilsner beer.

Interestingly, until the 1990s, Pilsner Urquell was fermented in traditional Bavarian oak vessels for seventy days ¹¹. However, with the fall of communism and the rise of the free market, there was a demand for faster production processes. To meet this demand, the brewery transitioned to stainless steel vessels, reducing the fermentation time to thirty-five days ¹¹.

Over the years, Pilsner Urquell has undergone various changes in ownership and production methods. It was nationalized in 1947 and later privatized in 1992 ². In 1999, it became part of the SABMiller group of companies and was later sold to Asahi Group Holdings in 2017 ². Despite these changes, Pilsner Urquell continues to be brewed in the same brewery, using the same recipe and traditional methods, including triple decoction, a complex mashing technique, and parallel brewing in wooden lagering barrels, a testament to its commitment to preserving its heritage ².

Different Styles of Pilsner Beer

While Pilsner Urquell remains the original and most iconic Pilsner beer, the style has evolved and diversified over time, leading to the emergence of distinct variations. Three main styles of Pilsner are recognized today: Czech, German, and American ⁹.

Czech Pilsner

This is the original style of Pilsner, characterized by a deep golden color, a balanced malt and hop profile, and a distinct bitterness ⁹. Czech Pilsners typically use light malt and Saaz hops, and the soft water of Pilsen contributes to their clarity and soft texture. They often exhibit a subtle malt sweetness with hints of toast or biscuit, balanced by the spicy and floral notes of Saaz hops.

German Pilsner

German Pilsners, also known as Pils, are generally paler in color than Czech Pilsners, ranging from pale yellow to light gold ⁹. They have a more pronounced hop character, with medium to high bitterness levels that linger on the palate. German Pilsners may use Saaz hops or other German noble hops, such as Hallertau or Tettnang. They tend to be drier and crisper than Czech Pilsners, with a greater emphasis on hop bitterness and a lighter body.

American Pilsner

American Pilsners are a more recent development, influenced by both Czech and German Pilsners. They often exhibit a higher level of bitterness than Czech Pilsners but less than German Pilsners ¹². It’s important to distinguish American Pilsners from “American light lagers.” While both are pale lagers, American light lagers are typically brewed with adjuncts, such as corn or rice, to lighten the body and reduce the intensity of flavor ¹². This distinction arose due to the differences between American six-row barley and European two-row barley, which led American brewers to incorporate adjuncts to achieve a similar flavor profile to European Pilsners ¹³.

Interestingly, the meaning of “Pilsner” as a style, rather than a geographically protected designation like some wine regions, was a legal construct, determined by politicians and judges ⁵. This highlights the complex interplay of brewing tradition, commercial interests, and legal frameworks in shaping the identity of beer styles.

Comparing Pilsner Styles

To further illustrate the differences between the main Pilsner styles, the following table provides a concise comparison:
