What is a lager beer?

Answered by Roy Gibson

is a type of beer that is light in color and highly carbonated. It is distinct from ales, which are British types of beer fermented from the top. As a sommelier and brewer, I have come to appreciate the unique characteristics of lagers and the process that sets them apart.

The term “lager” refers to beer that is produced using bottom-fermenting . This means that the yeast used in the fermentation process settles at the bottom of the fermentation vessel. This is in contrast to ales, where top-fermenting yeast rises to the top during fermentation. The use of bottom-fermenting yeast in lagers leads to a different flavor profile and brewing process.

One of the defining features of lagers is their light color. When I first started brewing lagers, I was struck by the pale golden hues that are characteristic of this beer style. This light color is achieved through the use of pale malts, which are lightly kilned and result in a lighter, less roasted flavor compared to darker malts used in ales.

Lagers are also known for their high level of carbonation. This effervescence adds a refreshing quality to the beer and enhances the overall drinking experience. When pouring a lager, you will often notice a lively stream of bubbles rising to the surface, creating a beautiful foam head.

The brewing process for lagers involves a longer fermentation and maturation period compared to ales. This is known as “lagering.” During this time, the beer is stored at colder temperatures, typically around 35-55°F (2-13°C), for several weeks or even months. This extended cold maturation allows the flavors to develop slowly and creates a smooth, clean taste.

I have had the opportunity to brew lagers in different settings, from small craft breweries to larger production facilities. Each experience has taught me the importance of precise temperature control during fermentation and maturation. It is crucial to maintain a consistent cold temperature to achieve the desired flavors and characteristics of a lager.

In terms of flavor, lagers are often described as crisp, clean, and refreshing. They typically have a milder taste compared to ales, with a smooth, well-balanced profile. Some lagers may have subtle sweetness, while others showcase a more pronounced hop bitterness. There is a wide range of lager styles, from the classic German Pilsner to the rich and malty Vienna Lager.

Lagers are incredibly versatile and pair well with a variety of foods. They complement lighter dishes such as salads, seafood, and grilled chicken, as well as heartier fare like burgers and sausages. The refreshing carbonation and balanced flavors of lagers make them a popular choice for many beer drinkers.

Lager beer is a light-colored, highly carbonated beer produced using bottom-fermenting yeast. Its distinct brewing process, including cold fermentation and maturation, results in a crisp, clean, and refreshing flavor profile. Lagers are a versatile beer style that can be enjoyed on various occasions and paired with a wide range of foods. As a sommelier and brewer, I appreciate the craftsmanship and unique characteristics that make lagers a favorite among beer enthusiasts.
