You may already realize that red wine is healthy for your heart. But do you know why? And why doesn’t white wine have the same benefits? The difference is in the skins.

The skin of a grape has a high concentration of an anti-oxidant called resveratrol, which the grapevine produces. The thicker the skin of the grape, the darker the wine and the more resveratrol there will be. Thick-skinned grapes like Cabernet Sauvignon, Malbec, Tannat and Nebbiolo  are therefore, the most heart-healthy.

Red wine goes through a period of skin contact that white wine does not, hence why red wine has the heart-healthy components and white wine does not.

Resveratrol is just one  of many heart-healthy substances in red wine, along with polyphenols, anthocyanins, and other anti-oxidants.
