Northern Spy may have originally been called Northern Pie Apple. Discovered in an orchard at East Bloomfield, New York, with seedlings brought from Connecticut about 1800. The fruit is large. Color is a clear-yellow shade with bright-red tints, distinctly streaked with the yellow under-color, making the red almost scarlet. The white flesh is very juicy, crisp, tender and sweet with a rich, aromatic subacid flavor. The hardy tree is upright, free-growing with long curved branches and dense foliage. The shiny, smooth leaves, are folded, reflexed, and slightly waved with sharp, shallow, and indistinct serrations. Subject to bitter pit and blossom fireblight. During rainy weather, the fruit may crack, and is easily damaged during harvest. Northern Spy blooms late and escapes frost, but it is slow to begin bearing. On standard rootstock, it may take10 years for the first harvest, but on size-controlling rootstocks, it can bear in 3 to 4 years. It contains 13.77% sugar that ferments to 6+% alcohol. One of the best storing apples, it ripens in late September and early October.
