<b>Scarcity of water</b>
EDITOR: Irrigating food crops, including grapes, is unnecessary and unsustainable. Drought-resistant perennials can and did provide sustainable food sources for a millennium.
Many vintners feel non-irrigated vines produce a finer quality wine. It's time to view non-irrigated food production as the "new green."
Using wine as an example, a label bearing a "non-irrigated" designation would command a higher price and a unique place on grocery shelves for wines using non-irrigated fruit. The increased demand and price would offset the reduced tonnage that may result from changing growing methods. It would appeal to a public that is becoming aware of the scarcity of water.
