Perry or pear cider is an alcoholic beverage made of fermented pear juice. It is similar to cider, in that it is made using a similar process and often has a similar alcoholic content, around 8% alcohol by volume.
Perry has been common for centuries in Britain, particularly the West Country and Wales; and France, especially Normandy and Anjou. Sweden also produces perry, such as Kopparbergs. As with cider, special pear cultivars are used. They produce fruit that is of poor eating quality, but that produces superior perry. Perry pears are higher in tannin and acid than eating or cooking pears, and are generally smaller.
Perry from Gloucestershire, Herefordshire and Worcestershire in England made from traditional recipes forms a European Union Protected Geographical Indication.
CAMRA's definition of "real perry" is in parallel to that of real cider:
"DEFINITION OF REAL DRAUGHT CIDER & PERRY
A) INGREDIENTS
- The liquid content before fermentation must consist entirely of non-pasteurized apple (Cider), or pear (Perry) juice.
- No apple or pear juice concentrates to be used.
- Normally, only the sugar naturally available in the fruit should be used to cause fermentation, but in years when the level of natural sugar in the fruit is low, the addition of extraneous sugar to aid fermentation is acceptable.
B) PROCESS
- No pasteurization to take place during the production process in relation to the cask product.
- No added colourings to be used.
- No added flavorings to be used.
- There must be no artificial carbonation for draught products.
- Sweetener may be added to fully fermented Cider/Perry to make it sweet or medium.
- The addition of water is permitted to bring the alcoholic content of the Cider/Perry down to the level required by the producer. Ideally, however the minimum juice content should not be lower than 90% volume.
- No micro filtration allowed (this takes all the yeast, leaving a "dead" product).
The above is item 5.2 as extracted from CAMRA's External Policy Document 2003 - 2004" (from CAMRA's Cider & Perry page)
Like commercial pale lager and commercial cider, commercial perry is highly processed and often contains large quantities of cereal adjuncts such as corn syrup or invert sugar. It is also generally of lower strength than real perry.
