For anyone that lives in the UK and loves apples, I would recommend the Apple Festival held at Brogdale, near Faversham in Kent [1]. Brogdale is the home of the UK's National Fruit Collection [2] and if you've ever wanted to have 30-40 varieties of apples and pears to taste and buy like a wine-tasting this is the place to be.
