Ale is a beer made using a specific yeast called Saccharomyces cerevisiae. This yeast ferments at warmer temperatures than the yeast used to make lager beer. Ales have a broader range of flavors and styles, with some common characteristics such as fruity, floral, and spicy notes. They can be further classified into subcategories such as pale ales, India pale ales (IPA), brown ales, and stouts. Pale ales are known for their hoppy flavor and amber color, IPAs are known for their intense hop bitterness and high alcohol content, brown ales are known for their nutty and caramel flavor, and stouts are known for their dark color and rich, robust flavor.
