Anchor Steam is classified as a lager, specifically a California common beer. This style of beer is unique to the United States and has a rich history that dates back to the late 1800s. The term “steam beer” was originally used to describe a type of beer that was brewed using open fermentation vessels and had a distinct steam-like appearance due to the steam rising from the hot beer during the brewing process.
However, it is important to note that Anchor Steam, as we know it today, is a modern craft-brewed lager. The Anchor Brewing Company, which trademarked the term “steam beer” in 1981, is the pioneer of this style and has been brewing Anchor Steam since the 1960s.
One of the defining characteristics of Anchor Steam is the use of a lager yeast strain at ale fermentation temperatures. Traditionally, lagers are brewed using a bottom-fermenting yeast strain that operates at cooler temperatures, while ales are brewed with a top-fermenting yeast strain at warmer temperatures. However, in the case of Anchor Steam, a lager yeast is used but fermented at temperatures more typical of ale fermentation.
This unique brewing process gives Anchor Steam its distinctive flavor profile. It combines the crisp and clean characteristics of a lager with the fruity and slightly estery flavors commonly associated with ales. The result is a beer that is refreshing, yet full-bodied, with a complex maltiness and a subtle hop bitterness.
I have had the pleasure of tasting Anchor Steam on several occasions, and each time I am reminded of its unique qualities. The beer has a beautiful amber color with a thick, creamy head that lingers on the glass. The aroma is reminiscent of toasted malt, caramel, and a hint of fruitiness. Upon taking a sip, I am greeted by a rich malt backbone that is balanced by a subtle hop bitterness, creating a harmonious interplay of flavors. The mouthfeel is smooth and medium-bodied, making it highly drinkable.
It is worth mentioning that Anchor Steam has become an iconic beer in the craft beer industry, and its popularity has led to the creation of similar styles by other breweries. While these beers may be inspired by Anchor Steam, they are not necessarily true representations of the original style. Anchor Steam remains a shining example of the California common beer style and continues to be brewed with the same dedication and craftsmanship that it has been known for over the years.
Anchor Steam is a modern craft-brewed lager, specifically a California common beer. It is brewed using a lager yeast strain at ale fermentation temperatures, resulting in a unique flavor profile that combines the best qualities of both lagers and ales. Its rich history, distinctive taste, and iconic status in the craft beer world make Anchor Steam a beer worth experiencing.
