黑啤酒, or "dark beer," is a type of beer that is characterized by its deep brown to black color. This color comes from the use of roasted malts or barley during the brewing process. Dark beers often have a rich, complex flavor profile, which can include notes of chocolate, coffee, and caramel. They typically have a fuller body and a slightly higher alcohol content compared to lighter beers. There are several styles of 黑啤酒, including 波特 (porter) and 斯托特 (stout). Each style has its unique characteristics, but they all share the common trait of being darker in color. Dark beers are popular in many cultures and are often enjoyed during colder months or paired with hearty meals.
