Foster's is a lager, not an ale. A lager is a type of beer that is fermented and conditioned at low temperatures, typically between 35-50°F (2-10°C), for a longer period of time compared to ales. This slow and cool fermentation process allows for the development of a clean and crisp flavor profile.
The distinction between lagers and ales lies in the type of yeast used during fermentation. Lagers are brewed using bottom-fermenting yeast strains, while ales use top-fermenting yeast strains. The yeast used in lagers tends to settle at the bottom of the fermentation vessel, resulting in a cleaner and smoother beer.
In the case of Foster's, it is specifically marketed as a lager. The brand was introduced in the late 19th century in Melbourne, Australia, where the climate can get extremely hot. The locals were accustomed to drinking British-style ales, which were not as refreshing in the scorching heat. Foster's filled this gap by offering a cold lager that was lighter and more thirst-quenching.
Personally, I have had the opportunity to taste Foster's Lager on several occasions. Its pale golden color and effervescence make it visually appealing. The aroma is mild, with hints of grain and a subtle hop presence. Upon tasting, Foster's delivers a clean and crisp flavor profile with a slight malt sweetness and a balanced hop bitterness. The carbonation level is moderate, contributing to its refreshing nature.
It is worth noting that Foster's Lager has faced some criticism and skepticism over the years. Some beer enthusiasts argue that the brand has become somewhat diluted and mass-produced, losing some of its original character. However, it remains popular in certain markets due to its association with the Australian beer culture and its easy-drinking qualities.
Foster's Lager is indeed a lager, not an ale. Its introduction in Melbourne provided Australians with a lighter and more refreshing beer option in the hot climate. While opinions may vary on its taste and quality, Foster's Lager continues to be recognized as a lager-style beer.
