Why is it perceive that Canadian pinot noir grape considered effective to prevent heart diseases?

Answer 1

Considering I am in Canada and I am in the wine industry I have to say that statement is false. Could it be a marketing idea to sell more Canadian Pinot Noir (which is very good these days)?

If you are looking for a grape with a high level of resveratrol (which is supposed to be good for preventing heart disease) I would look to the grape variety muscadine.

The article at the bottom talks about the benefits and also talks about a vitamin supplement that is available for those that don't want the risks associated with drinking alcohol but still want the benefits from the resveratrol.

Answer 2

I'm not a chemist, but my understanding is that the chemicals in grapes that lead to reduced risk of heart disease are the tannins. Tannins are bitter/dry-tasting compounds that are evident in most hearty red wines, and are partially responsible for giving red grapes their red color. The beneficial tannins are found in all grape varietals, although they have a much higher concentration in red grapes than in green grapes. The Canadian pinot noir grape (a red grape) would have roughly the same amount of tannins as any other red grape.

In wine, tannins promote dryness (bitterness or non-sweetness), and are responsible for an attribute known as astringency. This is a desirable quality in many red wines, and some better homebrew stores stock packets of grape tannin so that homebrewers can improve this quality in their wines. If you are interested, the grape tannin can be used as a dietary supplement which would give you the same benefits as drinking the recommended 1-2 glasses of red wine per day, or eating your pinot noir grapes.
