Erwin Bauer is a German apple, first introduced in Eastern Germany in 1928, but it did not become popular until after the war in 1955.
This heirloom is medium sized, with a deep yellow skin covered in dark red-orange stripes. This apple is large, sweet-tart, aromatic, and a good fresh eating apple. It is a seedling of Duchess of Oldenburg, but its fine flavor and aromatics so much resembles Cox's Orange Pippin that Cox is regarded as probable pollen parent.
The tree is small to moderate, and a heavy producer, annual bearer. In upstate New York, it ripens late autumn (October). Good keeper. Hardy to zone 4.
