Foster’s Lager is an internationally distributed Australian brand of 5.2% abv pale lager.  It is a product of Foster’s Group brewed under licence in several countries, including the U.S.  and Russia.   The European rights to the beer are owned by Heineken International, who brew and distribute a 4% ABV Foster’s in most European countries,  including the United Kingdom, Greece, France, Belgium, Portugal, Poland, Finland, Germany, Spain,Sweden, Ukraine and Ireland. In the United States  and India,  rights to the brand are owned by SAB Miller. In Canada, Foster’s is brewed by Molson Canada under licence from Foster’s Brewing International.

Foster’s brand is also used on several other beers, including Foster’s Premium Ale, and Fosters ESB (Extra Special Bitter) which has been discontinued.

In recent years, Foster’s has consistently sold in the region of 5 million hectolitres each year in the UK, making it the best selling beer after Carling. While international marketing of the beer often focuses on its Australian connections, Foster’s does not enjoy widespread popularity in Australia.
