I'm picking major weight of really beautiful Summer Beaut nectarines the last few days. Brix is lower than ever and less than earlier varieties, coinciding with very good size. The wet conditions seem to affect every variety differently. I expect some varieties coming up will be much sweeter and better. These will be fine for culinary use.
One thing I've observed is that on all varieties it is the individual fruit with no shine on the skin that have the highest brix. The beautiful, shiny ones are the bimbo nects. Ever noticed this Fruitnut?
I should mention that the fruit has not been sprayed with fungicide for 3.5 weeks and most is pristine and store perfect although we continue to get rain a couple days a week. Any rot is on a few cracked or otherwise damaged fruit- brown, not black. Summer Beaut has proven to be relatively crack resistant over the years here in NYS.
