Schwarzbier and Porter are both dark beers, but they have some key differences. Schwarzbier is a dark lager with a lighter body, smoother palate, and a cleaner finish due to the use of lager yeast and fermentation. Porters, on the other hand, are ales with a rich, roasted malt profile, a fuller body, and a more complex flavor that may include notes of chocolate, coffee, or toffee.
