Wickson, here in Northern California near it’s birthplace and very similar zone is a strong upright grower. The taste is phenomenal at it’s peak and pretty unique, though there are some similarities in related apples. It cracks badly, it’s major downside here.
Muscat de Venus is very sweet, has some similar flavor to Wickson, or at least it would seem they are related. I’ve never had it taste like grapes. It is a low acid apple, so it falls a little flat for me. I always think I should love it, but I just don’t quite. I crossed it with some other apples last year, so maybe those will inject some life into it. It seems like it has high potential for breeding. Vixen is quite similar to wickson, but a lot bigger, verging on normal size at times. It is not as rich and intense, but it still is both. Amberoso, another from that etter group has fallen flat for me. It has some interesting flavorsm again similar to the etter/wickson group, but it just doesn’t appeal that much in the end. I have one Wickson seedling BITE ME! , that is quite good, but it got scab very bad this year, so that may end up being it’s downfall. We definitely don’t have as much disease here as a lot of folks back east do.
