Question: is altbier an ale or lager?
Answer: Altbier, however, is not purely an ale, nor is it a lager. It is a hybrid. It's made with the pale malts and Saaz hops of a classic German Pilsner, plus some darker roasted grains; then it employs an aggressive, top-fermenting ale yeast that attenuates the wort completely to reduce the sweetness.
