Apples are a unique fruit. They enjoy an enviable reputation as one of the most popular fruits worldwide and are produced in almost every country that has a cool temperate climate. Together with oranges and bananas they dominate all markets by being available year-round. Crisp, crunchy fresh apples appeal to young and old alike, and they have the added advantage of being easily processed into juice, pulped for baby food, or canned or frozen for apple pies and bakery products.
