Accepting the figures from both U_R and S_S:
Body mass = 75kg x 0.68 = 51kg (effective mass)
Bottle = 750ml x 13% (ABV) = 97.5ml alcohol x 0.8 (SG) = 78g
So a bottle of wine would give a blood alcohol figure of 78/51 = 153, reducing to below 20 after 9 hours.
Humans can vary widely in the rate at which alcohol is absorbed and in the rate at which it's eliminated, so these figures should be treated as a very rough estimate (but look plausible, to me anyway).
