Real ales are traditional beers that are brewed using natural ingredients and undergo a secondary fermentation in the cask. This process allows the beer to develop its flavors and carbonation naturally, resulting in a unique taste profile. Real ales are typically served at cellar temperature and are often unfiltered, which means they retain more of their original character. In the United Kingdom, the Campaign for Real Ale (CAMRA) promotes the appreciation of real ales and supports local breweries. Real ales can vary widely in flavor, color, and strength, making them a popular choice for beer enthusiasts who enjoy exploring different styles and regional variations.
