Wales has fewer wineries and vineyards but the quality of some of the Welsh wines is quite outstanding. The Welsh Borders (between Wroxeter and Tintem) supply superb grapes for the best Welsh wineries, such as Three Choirs in Newent. The local Bacchus, Reichensteiner, and Schonburger. Travelling east from Wales one comes to the Thames Valley and Chiltem wine areas where the vineyards are mainly established between Oxford and Wantage, in area around Reading and Slough, and between Aylesbury and Hemel Hempstead. Further to the east is East Anglia, where there are vineyards between Norwich, Cambridge, Chelmsford, and Ipswich. To the south of this are perhaps the best-known English vineyards of Kent and The Sussex Weald (East Sussex). This is a very productive area and new English vineyards are being established or extended all the time. Excellent English wines are made at Biddenden, Elham, Tenterden, and Lamberhurst. The English vineyards of Surrey and West Sussex lie to the west of Kent and East Sussex and further west are those of Hampshire, the Isle of Wight, Wiltshire, and Dorset. Finally the vineyards of Devon and Cornwall are the most southerly British wine areas. The largest wine production comes from the South-East of England (includes Kent, East and West Sussex, Hampshire, the Isle of Wight, Oxfordshire, and Surrey), East Anglia (includes Essex and Suffolk), Wessex (Somerset and Dorset), the South-West (Devon and Cornwall), and South Mercia (Gloucestershire and the border counties).
