Thanks for the information everyone! I've tasted several different types of blood oranges including Morro, Torrocco, Sanguinelli and so far Morro is the best because it is the most consistent in terms of internal red color, flavor and sweetness. Unfortunately, most these varieties that I have tried are highly variable in terms of flavor sweetness and internal red color, except for Morro. Morro is variable in terms of flavor and sweetness but it is pretty consistent for internal red color. Morro is sour if picked too early and stale wine tasting if left on the tree too long.
I have not had the pleasure of tasting the Smith Red Valencia yet and I hope it compares favorably to the other blood oranges. These SRVs are very large, about the same size as a nice Cara Cara navel and the outside skin is getting a bit of red pigmentation.
The average Cara Cara I tested this year had 11% Brix, I hope the SRV has at least this much Brix if not higher. I only have 4 fruit on my small tree so I don't want to pick my fruit too early or too late. I'm really excited to finally try it and will definitely report back on flavor, color and sweetness. I'm really hoping it will be a good juicing orange because it's supposed to be a Valencia type orange.
