Tannins verses Reds

[pamelah148]

I've got a kind of medical related question for you guys and maybe you can answer it for me. What is it in the red wine that is suppose to help to lower blood pressure? Is it in the grape or the tannins of the grape?
I guess I ask because I was wondering if Zins being from red grapes would have the same properties for this as the red wines. If I have posted this in the wrong place let me know. I would appreciate it if someone would also recommend another sipping soft red wine that they have tried and liked quite well other than Reunite Lambrusco. This newbie still in the sweet phase. Is Oliver any good or is it just a pretty bottle?
