Wineries are notorious for using large amounts of water, with estimates ranging up to 20 gallons of water needed to produce a singe gallon of wine. Jackson Family Wines is one wine maker that has found a high tech way to put a billion-gallon dent in its own annual water consumption, and the implications could be enormous for wine rich, water poor states like California.

Jackson Family’s new water recycling system has just completed a “proof of concept” pilot run certified by the University of California at Davis. Once in full swing, the system will involve about 70% of the winery’s water use, which primarily goes to rinsing barrels and tanks. The new system will recycle 90% of that water for up to ten rinses but wait, there’s more: the recycled water also keeps 75% of its heat, which will save a significant amount of energy that would otherwise be needed to warm up cold water. - CleanTechnica
