Quadrupel Beer is a strong, dark ale that originates from Belgium. It typically has an alcohol content ranging from 10% to 12% and is known for its rich, complex flavors. Brewed with a variety of malts, it often features notes of dark fruit, caramel, and toffee, making it a favorite among craft beer enthusiasts. This style of beer is part of the Trappist and Abbey beer traditions, which are known for their high-quality brewing practices. Quadrupels are usually bottle-conditioned, allowing for further fermentation and flavor development over time. They are best enjoyed slowly, often paired with rich foods or desserts.
