I actually have several apples, but I don't speak of them much because I'm just not much of an apple lover (80% of this forum just recoiled in horror!!!). I've got Winesap, yellow delish, red delish, honeycrisp, Gala, Rome, Arkansas Black,, Liberty, and one unknown apple that best matches photos of gravenstein but its an old tree and I don't know what it is.
Glad to hear your Winesap did so well. I actually let mine fruit its second year, at least I left some on the tree so I could taste them, but I thinned it way, way down. The tree still grew like crazy so I bet it would be ok for you to do that, but I'm certainly no expert and will defer to others here if they say otherwise.
I just hope yours is what you think it is. It's no secret that I'm an advocate of big box trees in general (many here are not, and I respect that) but my one exception is Lowes. That is because I have honestly had more than 50% of the trees I've bought from Lowes- and there have been a LOT- turn out to be mislabeled. Think about that. More than 1 out of every 2 have been mislabeled. That is just insane.
