 The apple orchards produce the Vasquez and King David varieties, which are grown only in Oak Glen, as well as antique varieties no longer commercially available such as Ben Davis, Gravenstein, and Pink Pearl.Although Oak Glen grew apples mainly for export, in the 1940s several farms began to sell apples, apple pies, apple cider and apple butter at roadside stands.The export trade has virtually disappeared, and growers now earn much of their revenue from visitors who are allowed to pick apples directly off the trees at some of the orchards.
