On Jan. 26, UC Davis will host the first conference on hybrid wine grapes and their potential environmental and economic benefits to California’s wine industry.
Most wine is made with the European grape species Vitis vinifera, which has little resistance to pests, fungal diseases, extreme temperatures and drought.
Cross Vitis vinifera with a North American native species (like Vitis californica) and you get hybrid grapes, which are predisposed to withstand most pests, diseases and little water.
