Researchers at Northwest Agricultural and Forestry University in Yangling, China, have developed genetically engineered grapes that they say delivers six times the amount of resveratrol found in regular grapes.
Resveratrol is a compound in red wine that researchers believe helps decrease heart disease rates and may have other health benefits. The problem is that standard grapes do not provide high enough levels of resveratrol.
The Chinese scientists were able to add an extra gene from a wild Chinese vine, which triggers increased resveratrol production and also helps grape vines fight common vineyard plant diseases.
It will likely be sometime before wine from vines created in the research hits the market. It is also likely that consumers may question drinking genetically modified wine, even if it offers increased health benefits.
