US: Winery wastewater becomes fruit of their labor
US: Winery wastewater becomes fruit of their labor

(SFGate) - "Conserve water, drink wine," quips a common bumper sticker.
If only that were true. Making a gallon of California wine, by various estimates, requires anywhere from a few dozen gallons of water to a few hundred.
Most of that water goes toward irrigation. But some goes to the winery itself and comes out as waste. On average, wineries create 6 gallons of wastewater for every gallon of wine, which means that in 2010, the California wine industry produced enough to drown Golden Gate Park in more than 8 feet of runoff. About one-fourth of the industry's waste is produced at this time of year, during harvest.
