Stouts are a dark, rich style of beer known for their deep flavors and creamy texture. They are typically brewed with roasted malt or roasted barley, which gives them their characteristic dark color and notes of coffee, chocolate, and caramel. The alcohol content in stouts can vary, but they generally range from 4% to 8% ABV. One of the most famous types of stout is the Irish stout, particularly the well-known Guinness. Stouts can also be categorized into various sub-styles, including imperial stouts, which are stronger and more robust, and milk stouts, which contain lactose for added sweetness.
