Remarkably little information readily available out there about them. People only talk about color, not taste or texture. They look a lot like a red delicious in conformation, which would not be a good thing if that's also how they taste.

I read this “is sweeter and crisper than your standard varietal. That's because they have higher levels of natural glucose. The excess organic sugars in the apple make it naturally sweet, and its thick skin gives it a unique richness.”

Possibly a fancy way of describing red delicious as well 😀

But there’s always room for one more tree isn’t there, if the color is real.

You might consider another rare black apple:

The Devonshire Crimson Queen from QueenerFarm . Com as a VERY expensive scion.

Also the Black Oxford from Fedco Trees available as three different size trees or as a scion. I grafted this variety, which I obtained from Fedco, a couple years ago and it took and is growing fine.
