Grapes are the most planted fruit crop in the world, with more than 29,000 square miles (about 75,000 square km) of space being used and about 150 trillion pounds (68 trillion kg) of grapes being produced annually. The amount of land used for grape crops has been projected to increase 2% each year. The prevalence of grape crops is mainly thought to be because of their adaptability to most climates. The majority of grapes — about 70% — are used to make wine, but that figure can vary by region. For example, in California, more than half of the grape crops are either used as fresh fruit or dried into raisins.
