A wide array of health research funded by California table grape growers has been conducted over the years by institutions from around the world to help discover how and why grapes are beneficial to health. The research has covered a wide range of health topics including heart, brain, gastrointestinal, skin, joint, and eye health, as well as certain cancers. To view the list of funded research to date click here.


Grape research is conducted using a freeze-dried table grape powder, designed to facilitate reproducible data and to provide researchers with a grape sample that is available year-round. Additionally, a grape powder placebo is made available.


Each fall, Letters of Intent are solicited from the research community. Following review, finalists are invited to submit full proposals. A scientific advisory panel of distinguished scientists conducts the rigorous grant review and selection process.


Researchers interested in receiving notification for the 2024 Call for Letters of Intent may email the commission at [email protected] to be added to the mailing list.

Californians have been cultivating grapes for more than two centuries. Today, 99 percent of U.S. table grapes are produced in California's warm, dry climate that is ideal for grape growing. With 90 grape varieties grown, California grapes come in three colors—green, red, and black—and are in season from May through January.
