Howdy, neighbor! Swenson Red is an excellent grape, the only problem is it has seeds. My family doesn’t like seeded grapes so I topworked it last summer. The AK grapes are probably the best overall, but Jupiter I also like a lot. Flame is not any good in the east; Somerset I have heard great things about and I plan on trying it at some point. The AK grapes are taking awhile to come into full production, but I have had that to some degree on all my grapes as they are on a steep hill I don’t irrigate and they don’t establish very quickly at all. I would also consider some muscadines, they have seeds and are slipskin, but they also are much more flavorful. The other grapes taste like mild sugar water by comparison. They are also bulletproof in our climate.
For the apricots, I don’t think Robada is a good eastern cot, it gets too many skin and rot problems. I topworked mine last year. If you want another cot try Orangered or Ilona (the new NJ one, ACN is selling).
For heirloom fruits you might want a look at Ragan, an old book with geography based recommendations:
The zone 3 recs are generally pretty good for us. If you type Scott’s into the magnifying glass search in the upper right you will get my own apple and stone fruit experiences.
