Key Facts About Wine & Glyphosate

Infographic about "no significant risk" of glyphosate drinking wine

  • California’s vintners and growers have a long tradition of family businesses dedicated to producing high-quality grapes and wines and acting as stewards of the land for the long term. As global leaders in adopting sustainable practices, the California wine community adheres to environmental standards that are among the strictest in the world.
  • Glyphosate is an herbicide (or weed-killer) widely used by farmers and landscapers worldwide and also sold for consumer use in residential gardening. Many foods and beverages may contain minuscule, trace amounts. The U.S. Environmental Protection Agency (EPA) has established safe levels for glyphosate in over 150 foods and beverages.
  • Glyphosate is permitted for use in vineyards where it is used to destroy weeds. It is not sprayed on grapes or vines but targeted directly to vineyard weeds. The trace amounts of glyphosate that may be present in wine from its use on vineyard weeds are far below the safe level that the EPA has established.
  • Materials used in agriculture must meet stringent safety standards. Herbicides approved for use in the U.S. and other countries are thoroughly reviewed and studied by the EPA and other international governmental agencies. More information from EPA.
  • California’s Office of Environmental Health Hazard Assessment (OEHHA) adopted a regulation in 2018 establishing a No Significant Risk Level (NSRL) for glyphosate of 1,100 micrograms per day. The level that might be found in wine, if any, is insignificant compared to the NSRL. Because of this, wine is exempt from a new requirement to display warning signs for glyphosate within California.

What the Experts Say

“Wine as a source of glyphosate should not be of concern. An adult would have to drink more than 140 glasses of wine a day over 70 years containing the highest glyphosate level measured to reach the level that California’s Office of Environmental Health Hazard Assessment (OEHHA) has identified as ‘No Significant Risk Level.’”
