Apples can last up to two months in the refrigerator. The date an apple was picked and the variety of the apple impacts its shelf life. Firmer varieties, such as Granny Smith apples, last longer than softer varieties.
The shelf life of apples can be extended if they are placed in a crisping drawer or in a tightly sealed container. If an apple has wrinkled skin and brown spots, then it has gone bad. Soaking apple slices in lemon juice helps prevent them from browning.
Apples are available in 7,500 varieties. The state of Washington produces the most apples in the United States.
