Real ale is a type of beer that is brewed using traditional methods and is naturally carbonated. It undergoes a secondary fermentation in the cask, which allows it to develop its flavors and aromas over time. Real ale is typically served at a slightly warmer temperature than regular beer, enhancing its taste and complexity. In the United Kingdom, real ale is often associated with the Campaign for Real Ale (CAMRA), an organization that promotes its production and consumption. This style of beer is usually unfiltered and unpasteurized, preserving the natural ingredients and providing a unique drinking experience.
