Several varieties of pears can be stored for fall and winter use in a basement fruit cellar. They should be picked at optimum maturity when they are hard and the color has changed from dark to pale green. Select only perfect specimens for storage.
Pears are very sensitive to temperature and should be stored at 29 to 31 degrees Fahrenheit. The storage life of some pears can be one third longer at 30 degrees Fahrenheit than at 32 degrees Fahrenheit. Also, precise temperature control is required to prevent freezing.
Pears lose moisture rapidly. For storage, wrap individually in tissue or newspaper and store in cardboard boxes lined with perforated plastic.
Pears ordinarily do not ripen at storage temperatures as do apples. If pears are stored too long or at too high (above 85 degrees Fahrenheit for most varieties, but as low as 70 to 75 degrees Fahrenheit for Keiffers) they will break down without ripening, often becoming rotten inside while the outside looks sound.
