During some hot and dry summers I had to add water to wild mulberries and blackberries to be able to get a granita. Didn't try to make a sorbet, but I suspect I could go without adding sugars.
Yeah, that's why for sorbets I've been using a refractometer. If the Brix of a berry is, say 50% higher than average, then you calculate the formula by multiplying the solids, the POD (sweetness), and the freezing point depression by 1.5. This would definitely change the balance of added sugars.
