How much water do you use in a day? If you calculate how long your shower is, how much you drink, and what you use to cook with, you're far off the mark. Your cup of tea holds 30 liters of water, not 8 oz. A hamburger for dinner has you drinking 2400 liters of water, and even your shirt holds 2500 liters; just drinking a glass of wine, you're using 120 liters of water. (waterfootprint.org)
Where does this phantom water come from? The water that's used to produce anything -- food and material products -- is much more than what's presented in the final product. We strive to produce d'UVA in the most sustainable way possible, but all those grapes don't survive on dust. Wine will be used as a substitute for fruit necrtars in this article. The processes of wine production are close to those of nectars, and, althought they are not a non-alcoholic wine nor a glorified grape juice (rather, a beverage with its own delicious qualities!), it is produced in the same way up until the fermentation, which doesn't use water, anyway.
The buzz-word “carbon footprint” is all over the place these days, but how often do you hear “water footprint?” It’s an important concept that means the amount of water you use, directly and indirectly. Virtual water is an indirect example, and conveys the amount of water used to make a product.
