There are more than 7,500 known <a href=\"/wiki/List_of_apple_cultivars\" title=\"List of apple cultivars\">cultivars of apples</a>, resulting in a range of desired characteristics. Different cultivars are bred for various tastes and uses, including <a href=\"/wiki/Cooking_apple\" title=\"Cooking apple\">cooking</a>, eating raw and <a href=\"/wiki/Apple_cider\" title=\"Apple cider\">cider</a> production.
