Apples fresh from the orchard are a delicious fall treat. Many varieties of apples keep well for long periods, provided they're kept cool. In general, harder, tarter apples keep the best, so choose varieties such as Cortland, Liberty, Jonalicious, Northern Spy or Winesap. A second refrigerator is the best place to store apples, although an unheated garage or insulated storage shed can work as long as it doesn't get too hot or too cold.
Sort your apples and remove any bruised or damaged fruit. Bruised fruit gives off more ethylene gas, which leads to early spoilage.
Place apples in cardboard boxes or wooden crates, stacking them loosely in the containers to allow for air circulation.
Store apples above 30 degrees F and below 45 degrees F. Oregon State University Extension recommends an ideal storage temperature between 30 and 32 degrees.
Place a pan of water on a shelf separate from the apples to raise the level of humidity.
Sort through the apples once a week and discard any bruised or decaying fruit.
