@SMC_zone6, I think your observation of berry notes is accurate. Better than my description. I really liked those apples. It’s a little challenging to see when they ripen, because the skin remains greenish, but with a slight yellow tint. I hoped the red pigment would slow browning of the cut apple, but I dont think it makes much difference there.
People are really interested when I cut the apple and they see the red / pink interior. But they are also quite delicious and from my first year experience, they look quite productive.
I tried grafting Firecracker, but it didn’t take. Maybe next year if they have the scion again. Three years ago I grafted Redfield, from Fedco, and it took but was such poor vigor, I removed it.
