I am convinced that alcohol in volume is not paleo. I am also convinced that the purported health benefits of red wine are overstated. For instance, it takes many glasses of wine to get sufficient resveratrol.
I don't care. I drink wine because I want to and am willing to pay the cost. But rather than being a daily drinker, I have evolved into more of a collector only drinking very nice bottles every month or two.
Regarding carbs, I wouldn't worry about the sugar content of a port or a sauternes. I mean, how much do you plan on downing?
Oh, and most good sherries are in fact dry. At least your olorosos, finos, amontillados -- the kind you consume with tapas.
