My first of the season:
Texture was the biggest difference I noticed, though the So has a sweet-tart component that the Sugar Cane lacked. I need a bigger sample size to make up my mind. But, I won’t get that this year, as the Sugar Cane only set 2 fruits (2nd should be ready in a few days). Only 1 of the many fruit on So were ready, so Sugar Cane may be slightly earlier.
Both are considerably more juicy than the ones I’ve been getting from Roger Meyers in CA (I ordered 30 lbs of them, as my trees are still young). The CA ones are very sweet (some max out my refractomer, which goes up to 32) and reasonably firm (only the larger ones, a different variety I think, are a bit spongy), but are still much dryer.
