When it comes to beer, the term “Oktoberfest” refers to a specific style that originated in Germany. To understand what makes a beer an Oktoberfest, it's important to delve into its history and characteristics.
The Oktoberfest beer style, also known as Märzen, has its roots in the spring season. In fact, the name “Märzen” translates to “March” in German, which is when this beer was traditionally brewed. Back in the day, brewing in March was common because it allowed the beer to be stored and aged over the summer months when brewing was typically avoided due to the risk of bacterial infections.
One of the defining features of an Oktoberfest beer is its toasted bread or biscuit-like malt aroma and flavor. This is achieved through the use of specific malts, such as Munich malt, which provides a rich and slightly sweet malt character. The malt is kilned or roasted to bring out those toasty and bready notes that are characteristic of the style.
Oktoberfest beers also tend to have a medium to full body, with a smooth and creamy mouthfeel. This is achieved through the use of lager yeast and a longer fermentation and conditioning period. Lagering refers to the process of storing the beer at low temperatures for an extended period of time, allowing the flavors to mellow and the beer to become clean and crisp.
In terms of appearance, Oktoberfest beers typically have a deep amber to copper color. This is again a result of the malts used, which impart those rich and warm hues. The beer may also have a slight haze, but should still be relatively clear.
When it comes to the alcohol content, Oktoberfest beers are usually on the stronger side compared to other lagers. They typically range from 5% to 6% ABV, but can sometimes reach higher levels. This higher alcohol content was originally intended to help preserve the beer during the summer months before refrigeration was widely available.
Now, you might be wondering about the connection between Oktoberfest and the famous festival held in Munich. Well, the stronger version of the Märzen beer was traditionally served at the early Oktoberfest celebrations. Over time, this beer became synonymous with the festival and took on the name Oktoberfest.
To summarize, what makes a beer an Oktoberfest is the use of specific malts that create a toasted bread or biscuit-like aroma and flavor, a medium to full body achieved through lagering, a deep amber to copper color, and a higher alcohol content. It's a style that originated in Germany and has become closely associated with the Oktoberfest festival. So, next time you raise a glass of Oktoberfest beer, you can appreciate its rich history and distinctive characteristics.
