There are now 500 working vineyards around the UK, and nearly half of those welcome visitors. Spring and summer are the best times to go, when many have winemaker-led tours or self-guided walks. Often small and independent, no two vineyards are alike, but all offer an interesting foodie angle on the British countryside. Yes, they are all trying to sell you something, but it's not a hard sell when you're into their sparkling wares. These are our 14 favourite vineyards in England and Wales.
