text: However, perry (often marketed under the name "pear cider", see below) has increased in popularity in very recent times, with around 2.5 million British consumers purchasing it in one year. In addition, various organisations have been actively seeking out old perry pear trees and orchards and rediscovering lost varieties, many of which now exist only as single trees on isolated farms. For example, the Welsh Cider Society rediscovered the old Monmouthshire varieties 'Burgundy' and the 'Potato Pear', as well as a number of further types unrecorded up to that point.
  Naming controversy
  Pear cider has been used as an alternative name for alcoholic drinks containing pear juice, in preference to the term perry. The term has been dated to 1995, when Brothers Cider found that nobody at Glastonbury Festival understood what perry was; they began telling customers that it was 'like cider, but made from pears'.
  In the UK the new name has caused controversy. The Campaign for Real Ale (CAMRA) defines perry and pear cider as different drinks, stating that 'pear cider' as made by the large industrial cidermakers is a pear-flavoured drink, or more specifically a cider-style drink flavoured with pear concentrate, whereas 'perry' should be made by traditional methods from perry pears only. The National Association of Cider Makers maintain that the terms perry and pear cider are interchangeable, and its rules specify that perry or pear cider may contain no more than 25% apple juice.
