Resveratrol in Grapes & Grape Juice

Updated on September 1, 2011
Red grapes and red grape juice contain resveratrol, but not a whole lot.
Red grapes and red grape juice contain resveratrol, but not a whole lot.

Resveratrol, well known for its powerful longevity and health benefits, is popularly known to be found in red wine. It is - red grapes (or, rather, their skins) are rich in resveratrol, and the process by which red wine is made allows alcohol to leach out the resveratrol in grape skins and must into the wine. (The lack of this long maceration step is why white wine is relatively low in resveratrol)

But how much resveratrol can you find in red grapes and in red grape juice? Is it comparable to what you find in red wine?

Before we even start addressing with numbers, it's important to understand that resveratrol can appear in different quantities in red grapes. Grapes that are grown in moist climates have more resveratrol than the same grapes grown in dry climates, because resveratrol is a phytoalexin that the plant uses to ward off fungal attack which is more common in more humid climates.

Also, another compound found in grape skins, piceid, is converted to resveratrol during the wine-making process, so red wine will tend to have more resveratrol than a comparable amount of red grape juice, in which a greater proportion of unconverted piceid will be found.

As for quantities? Be prepared to eat a lot of grapes, or drink a lot of grape juice, in order to get the same amount of resveratrol that you find in resveratrol supplements (which use Japanese knotweed, an herb, as the resveratrol source).

Red grape juice: 1.14-8.69 mg resveratrol per liter of juice*

Red grapes: 0.24-1.25 mg resveratrol per cup (160 g) of grapes*

Most supplement pills have 25 mg or more resveratrol per pill, so the equivalent of what you'll find in grapes or in their juice is relatively small. However, red grape juice will have about 5 to 20 times the resveratrol of a similar amount of white wine. Red wine, though, can have as much as 2-3 times the resveratrol of white wine, but still quite a bit less than your average resveratrol supplement.

      I have wondered about the best sources for resveratrol ever since I started reading about it. Thanks for clearing that up for me with this article. Really appreciate it.

      Good information, more of a challenge to grow them in humid conditions but in the end it sounds like you may have a healthier eating grape.

      LivingNatural: I think so. The humid environment which the mold loves probably makes your grapes create more resveratrol as a natural antifungal.

      Very good information, we have a small vineyard in the midwest, very humid at times, and we do have fungal disease problems which we are addressing with organic treatments. I am guessing our red grapes would have higher content of reservatrol??

      Hi Marisue, thanks for stopping by! I wrote a Hub a while back about the benefits of resveratrol:

      Thank you for speaking up for resveratrol - which we should be consuming regularly. When I remember to take my supplements, I feel so much better. I love red grapes, and so I find I do well with consuming both supplements and the fruit. Thanks for listing the benefits of both.

      Could you elaborate as to the benefits of resveratrol in your research/experience?

      I had heard that red grapes and red wine were healthy but I never knew why. I learned a lot from your hub.

      Interesting hub. I am drinking some red grape juice right now (no preservatives, added sugar etc). I avoid wine as the preservatives affect me badly.

      I wonder if Concord grape juice is just as beneficial as red wine as far as the amounts of resveratrol.

      It sounds like a supplement from knotweed is the most efficient. Thanks for the informative hub.

      Thank you, zzron and ocbill. I love grape juice, too, although it is high in sugar. Having a little resveratrol doesn't hurt. :)

      I love red grape juice the most. I tried an organic brand and the difference was incredible. I can't go back to W-elc-hs
