A lager is a type of beer that is recognized by its high carbonation level and light color, though some modern lager beers are darker in color and may even be black. The yeast that is used to make lager beer is referred to as bottom-fermenting yeast. Ex. Grolsh, Stella Artois, Session, Honey Brown, St. Pauli Girl, Amstel Light, Dos Equis, Samuel Adams Boston Lager, Shiner Blonde, and Red Stripe.
