Late-maturing varieties of apples will store for use throughout the winter if the fruit is hard, mature, and in perfect condition. Apples picked too green (unripe) are subject to a number of storage disorders, such as scald and bitter pit; if picked beyond maturity, they quickly become overripe in storage. Cool fruit as quickly as possible after harvest for best results. For most varieties of apples, the optimal storage temperature is 30° to 32°F with a 90% relative humidity. Higher storage temperatures reduce the storage life considerably. Apples ripen twice as fast at 40°F as at 32°F. Substantial storage differences exist between varieties. ‘Goldrush’, ‘Fuji’,’ ‘Arkansas Black’, and ‘York’ all store exceptionally well.
