Real ale
Real ale is a type of beer defined by its traditional production. Also known as "cask conditioned" beer; the fundamental distinction between real and other ales is that the yeast is still present at the point of consumption, meaning it is unfiltered. Because the yeast is still alive, the process of fermentation continues in the cask or bottle on the way to the consumer. This secondary fermentation allows for the development of greater complexity in the taste, giving real ale its distinctive flavour. Another distinction made, especially in the United Kingdom is that Real Ale should be served without the aid of carbon dioxide or Top Pressure as it is known. Common methods of dispense are the Hand Pump, Electric Pump or by gravity.
This fermentation process is by no means unique to ale, it is also commonly used in any number of traditional beers, notably the dopple and tripple beers from Belgium and Germany. The name was brought into widespread use in the United Kingdom, CAMRA (Campaign for Real Ale) work to promote real ale, as opposed to the many keg beers that were being called ales in the UK during the 1970s.
There are literally hundreds of breweries in the UK which produce Real Ale and the list is ever changing. There is a steady erosion of some of the older names through closure or merger, but to offset this there are many new breweries, especially Microbreweries opening. Well known breweries include Adnams, Theakston and Hog's Back Brewery.
More information on which companies are brewing beer and where their beers are sold can be found in publications such as the and the CAMRA .
There are also a huge number of on-line resources for Real-ale information, among which the site is a reasonable start point.
