Origin: Formed within English, by compounding; originally modelled on an Italian lexical item. Etymons: cryo- comb. form, extraction n.

Etymology: < cryo- comb. form + extraction n., originally after Italian crioestrazione (1961 or earlier). With sense 2 compare slightly earlier cryoextractor n.

1. Winemaking. The practice of cooling grapes to a point where unripe grapes freeze, thus yielding juice only from the ripest fruit when pressed, and used esp. in the artificial production of ice wine.

1962 Ital. Bks. & Periodicals Jan.–Feb. 137/1 E. Gervasi. Il freddo in enologia (Cold temperature in wine production). The necessity for cooling in wine production is stressed, particularly in the stabilisation of wines, the thermal control of fermentation, their saturation with carbon dioxide and their concentration by cryo-extraction.

1988 Wine East Nov.–Dec. 12/1 The use of selective cryoextraction in winemaking is a new technology largely based on tests conducted in Bordeaux in 1985. Through the selective freezing of grapes prior to pressing, it has been found that there is an increase in the sugar levels of the resulting juice.

1990 J. Ayto Glutton's Gloss. 103 Experiments are under way in France with a technique known as cryoextraction, in which the grapes are picked and then artificially frozen before pressing.

2004 Vancouver Sun (Nexis) 29 Mar. f3 Fake icewine is often made from grape juice concentrates or from grapes that are frozen in a freezer, using a ‘cryo-extraction’ process.

2. Ophthalmology. Surgical removal of the lens by means of an instrument with a tip cooled to freezing point, to which the lens tissue adheres; an instance of this.
