The Science Behind WellVine™ Chardonnay Marc


Collaborative research between Sonomaceuticals, LLC, the USDA Agricultural Research Service (ARS), and the University of California Davis (UC Davis) spanning several years has revealed new potential in using Chardonnay marc to produce food and dietary supplement ingredients with health benefits due to the high concentration of naturally occurring nutrients.

the health-boosting benefits of flavanols

Chardonnay marc contains high levels of flavanols which are rich in antioxidant activity. Research shows that adding more flavanols to your diet is a great way to help keep your body healthy.

Potential Health Benefits of Chardonnay Marc

Prebiotic and gut health: Chardonnay marc is packed with oligosaccharides, a kind of fiber known to have the potential to stimulate the growth of good bacteria in the gut.

Cardiovascular health: Much of the phenolics in chardonnay marc are flavan-3-ols with high levels of epicatechin. Multiple research studies have shown flavan-3-ols to have positive effects on the cardiovascular system.

Help maintain normal blood sugar: Initial data from a study published in the journal of the American Society of Nutrition suggests that consuming a blend of Chardonnay marc and Chardonnay seed extract may help maintain normal blood sugar in overweight individuals.


What was once a by-product of winemaking has been re-imagined into this new superfood. A win for our palates and planet.

Our challenge:Nearly half a million tons of underutilized grapes each year

Grape marc, the remaining grape pulp, skin and seed after pressing, makes up the largest underutilized by-product from winemaking, with over 1.1 million tons generated in 2019 in California alone.

Our solution:Upcycling Chardonnay Marc for Zero Waste

By upcycling the Chardonnay marc by-product of winemaking into ingredients used in foods and dietary supplements, WellVine™ is enabling more sustainable wine production.
