Considering that alcohol itself is tasteless, what do people actually drink the stuff for? Any taste an alcohol containing drink has should not be too hard to copy with the current techniques, and the only other thing is the intoxicating effect, for which most people need more than the 1-2 healthy glasses.
(Used to drink alcohol, but didn't like it all that much better than non-alcoholic beverages, nor did I like totally loosing my balance (only effect it had on me, nearly killed me when I fell sidewards with my head between 2 small concrete pillars))
