I used to buy Baldwins from an orchard that has since bit the dust, generally a pretty good large apple. They seemed at their best if not stored more than a couple months though. I know they are a triploid variety. Don't know much else.

I grow Grimes Golden. It's a hard large green/yellow apple, with very good taste. It's also a good pollinator. I like it better than Goldrush.

CC, Everything I read is Baldwin is a Large tree especially on its own rootstock and even with a semi-dwarf rootstock. Don't think you can get it on dwarf as it wants to be a larger tree so hope you have the room. I have tasted and its my kind of apple, Crisp and some acid. The Grimes Golden I haven't tasted but grafted several last year. Hope Rayrose is right, I grafted so many antique varieties last year and then started to ck pollinator's and found out I have very few that are self fertile.
