Gravenstein apple trees require no introduction in Northern California where it has long been the premium variety. The Gravenstein apple tree was discovered in 1669 as a chance seedling in Denmark. The Gravenstein apple tree was introduced to California in the early 19th century, perhaps by Russian fur traders, who are said to have planted a tree at Fort Ross in 1811. Gravenstein apples are medium to large, skin thin, tender, greenish-yellow with broken stripes of red. Flesh firm, crisp, juicy, tart. Good for eating fresh, and one of the best apples for pies, sauce and juice.
