Ale is a broad category of beer brewed with top-fermenting yeast at warmer temperatures. Fermentation usually takes place between 15–24°C (59–75°F). Ales typically have a wide range of flavors, from fruity and spicy to rich and malty. Styles include pale ale, IPA, porter, and stout. Historically, ale was the most common type of beer brewed before lagers became widespread.
