Milk stout is a type of dark beer that is brewed with lactose, a sugar derived from milk. This ingredient adds sweetness and creaminess, resulting in a smooth and rich flavor profile. Milk stouts typically have a lower alcohol content compared to other stouts, making them more approachable for casual drinkers. The style originated in the 19th century and was initially marketed as a nutritious beverage. Brewers often use roasted malts, which contribute to the beer's dark color and flavors of chocolate and coffee. Milk stouts are enjoyed for their velvety mouthfeel and are often paired with desserts or enjoyed on their own.
