Lager is a type of beer that is fermented and conditioned at a low temperature, typically between 40-55 degrees Fahrenheit (4-13 degrees Celsius). This type of beer is known for its crisp, clean taste and light to medium body. Lagers are typically brewed with bottom-fermenting yeast strains and are aged for a period of time, allowing for the yeast to settle to the bottom of the fermentation vessel. This aging process, also known as lagering, helps to create a smooth and balanced flavor profile. Some popular styles of lagers include Pilsner, American Lager, and Dunkel. Lagers are generally lighter in color and have a lower alcohol content compared to other beer styles such as ales or stouts.
