Welsh beer is generally regared as beer brewed in Wales. It has a similar history and tradition to beer brewed in the rest of the British Isles. Wales, along with the rest of Britain, came under the influence of the temperance movement, and there has historically been a lot of heavy industry such as coal mining in south Wales. This has given some people the impression that all Welsh beers have been very weak. However, as with beers all over Britain, alcohol percentages vary.
