My daughter bought a house in St Paul that has an apple tree that is about 35 feet tall. It had tons of apples on it which started falling in late July and just finished in the last week or so. We have no way of knowing what variety of apples they are, but delicious for fresh eating and make great apple sauce that needs no added sugar. How can we go about identifying the sort of apples they are? See photos. A strange characteristic is that they start to smell fishy when stored in the refrigerator. Thanks, Mary PS. I suspect the tree is quite old.
