Chappell and Shenandoah are definitely worth considering. Chappell seems like a crowd pleaser with high sweetness and good flavor and is known to be a strong grower (though they haven’t been any more vigorous for me than the other 2 KSU cultivars).
I really like Shenandoah. It is precocious, reliably productive for me, they keep well in the fridge, and are healthy trees. I also really like how spread out the ripening season is. It starts early and yet finishes late due to dropping fruits slowly over a long period of time, as opposed to dropping most of its fruits all at once like PA Golden and Allegheny did for me this year. If your goal is to have a wide range of flavors, than a mild/subtle type like Shenandoah should definitely be among them imo. I don’t taste an eggy flavor when I eat Shenandoah fruits, but they are rather custardy in texture and often have vanilla notes to them, so comparisons to vanilla custard make a lot of sense for that variety.
I haven’t tried Potomac, so I can’t comment on that one.
It’s been a long time since I’ve tasted Susquehanna, so I can’t comment too much on that one either. My largest Suquehanna tree should’ve fruited for the first time this year, but ambrosia beetles killed it. Some people mention health issues with it, but I haven’t noticed that yet.
Allegheny is a must have for unique flavor as well. I mentioned one of the fruits having an orange sherbet component to the flavor before. This year I tasted that in most, if not all, of the fruits. Whether that is due to maturity of the tree or my taste buds or brain picking up on it more easily now, I don’t know. It is a higher maintenance tree due to the need for fruit thinning, but at least you know it will be productive.
Wabash and Benson tasted very similar to me. This was my first year tasting Benson though. Both are round, firm textured, very sweet, and have caramel notes to the flavor. I’m curious if other people feel the same way about Wabash and Benson tasting similar. I liked Benson better, so I would go with it over Wabash. The texture is smoother than Wabash and I don’t like how fast Wabash fruits oxidize and turn brown.
Not many people have tasted a wide range of different pawpaw cultivars and documented their experiences. Even less have grown a wide range of cultivars and compared and detailed their growing experiences. That takes a lot of time with pawpaws. We do have a lot more people doing that sort of thing now compared to 5 or 10 years ago. Everyones sense of taste varies as well, so it’s hard to get on good consensus on some cultivars when it comes to flavor profiles.
There are some nice, concise videos that Tim Lane posted of some of the different pawpaw cultivars and he talks about how they taste. Those are well worth checking out if you haven’t done so already. Look up Ockoo Farm on Youtube.
