Question: how many litres of water does it take to make a bottle of wine?
Answer: Wine's Mammoth Water Footprint: 120 Liters To Make One Glass? I ran across a surprising article in the Economist this week (Thirsty Work) which tells me that it takes 960 liters of water to make a single liter of wine. Or 720 liters of water for a 750 ml bottle.
