I bought a random unlabeled apple tree from a sale bin for $5 three years ago. It's finally produced one full-sized apple. Does anyone have any clue what variety this might be?
The people who really know what they're talking about will say it's hard to identify by sight alone. But it looks alot like my Liberty apples. It's a macintosh relative with a little more tartness than macs. It could be another apple also.
Definitely looks like it could be Liberty- That good, rich, deep red (almost black) recalls the heritage of Liberty apple. I think it is heavy in Macoun, Detroit Black, Fameuse- so dark on the outside, bright white on the inside (although often streaked with red inside in my experience.)
If it's really tasty and a mediocre keeper, ripens midseason and is remarkably disease free, but attracts codling moth, it could well be Liberty.
