How much Water in your Water?

Ever wondered how much water it takes to make a pot of coffee?
I hadn’t.  At least until I saw today’s blurb on The Economist about new research exploring the true amount of water it takes to produce and transport beverages.

I’ve certainly wasted my share of water homebrewing beer.  No doubt more liquid volume goes down the drain than in my belly… and I’m buying already malted barley, which is apparently the most water-intensive part of the whole process.
I’ll be honest, I don’t totally understand WHY it takes so much more water to make a liter of coffee (1,120 liters of water) compared to a liter of tea (120 liters of water).  Even the rather informative waterfootprint.org product gallery doesn’t go into much detail.

A pretty interesting way of looking at beverages.
