Small Size Cider Operation

As one of my income streams I want to produce cider. I have been reading about english cider production and have talked with cider producers. A small size cider operation that could be profitable is a minimum of 2000 cases. 2,000 cases is equal to 18,000 liters. A standard 2,000 liter tank used for cider production requires 180 bushels. A bushel of apples in the US is 48 lbs and 2,000 lbs is a ton. With that said a ton of apples is equal to 41.66 bushels(2000lbs/48lbs). From my readings a good cider orchard will produce 5 tons per acre. Back to the origional numbers if I need 2,000 cases or 18,000 liters I need 9-2000 liter tanks full of juice. So 9 x 180 = 1,620 bushels. At 5 tons per acre 5 x 41.66 bushels a ton = 208.3 bushells an acre. In an ideal world with good fruit production I would need 7.77 acres of apple production (1620 bushels needed / 208.3 bushells an acre ). If you want to check the math please do. Next we need to look at the types and percentages of those types that need to be planted on this hypothetical 7.77 acres.
