I drink wine - but I very seldom take it backpacking. it's too heavy. (I have been known to put two bottle of wine into a platypus at a resupply point tho..)

As I also drink scotch, cask strength single malt is far more weight efficient.

Of course the most weight efficient is probably crystal light powder and dual use everclear (stove fuel + booze) - but I'm a bit too much of a princess for that these days
