Winery Water Reuse - A New Varietal of "Purplewater"?

This article from the Environmental Leader caught my attention given that Oregon considers their wines superior to the California wines.  The maker of the Kendall-Jackson wines has been testing the concept of filtering rinse water that is recycled from a number of winery uses resulting in annual reductions of 6 million gallons of water, 133,000 kWh of electricity, and 73,000 therms of natural gas.

The article goes on to say:

"The process, which returns 90 percent of water and allows reuse of rinse water up to ten times, also has some energy-saving benefits. Because the recycled water retains 75 percent of its heat, the process reduces energy use and cost in the acquisition, heating, transfer, cleaning and dispersal of water.  In addition to water and energy savings, wine material removed during the filtering process can be co-composted with other organic materials, used as a natural fertilizer, or put toward energy creation in a bio-digester system. In July, the winery said it hoped to save $100,000 a year in electricity costs after a lighting retrofit at its 11.5 acre Kittyhawk location, a central production and storage facility."

Talk about the energy-water nexus!  Oregon Wine Board  take heed.  California wines are giving a new definition to sustainability when it comes to certification of sustainable viticulture.  Perhaps Oregon wines can add an emphasis on water reuse to their certification process.  It sounds like it is time to revisit Kendall-Jackson's excellent Merlots to celebrate their entry into the Rainbow Water Coalition.
