Below is a post I made in another thread from 2021 season (You can find more discussions about the apple if you search for Black Oxford). They are better flavor after a month or so in storage.

My Black Oxfords were darker than usual this year, larger, too, and good flavor right off the tree. It appears this apple liked the unusual long, hot summer we had. And I liked the harvest! The large size was likely due to the “natural” thinning thanks to hard freezes late May during blossoming. But I still got 33# of real nice fruit. REally nice when I didn’t think I’d get any. Sue
The fruit actually was darker than shows in the photo. I had a hard time getting good color. But they sure shined up when polished. REally beautiful.
