Wine which is grown and produced in the United Kingdom is generally classified as either English wine or Welsh wine (depending on country of origin), but should never be referred to as British wine as that term is generally linked with an inferior grade of product (more on that later). Traditionally seen as struggling with an unhelpfully cold climate, the English and Welsh wine industry has been helped by the warmer British summers over recent years and it is speculated that global warming may encourage major growth in the future.

The United Kingdom is a major consumer, but only a very minor producer of wine, with English and Welsh wine sales combined accounting for just 1% of the domestic market.
