A small glass of grape juice has health benefits too. Most of the time fruits and vegetables with dark pigments are powerful antioxidants. While I'm not sure if those antioxidants help with heart disease, it would be interesting to see if non-alcoholic options prove to be beneficial.
Briefly there was a grape juice on the market made with wine grape varieties and it was really good. It's the variety of grape that stands out the most in the flavor of wine, so the juice tasted basically like wine. Maybe not as complex and nuanced as a properly aged cabernet sauvignon or merlot. But it little glass of it with breakfast was a nice treat and I prefer it over orange juice.
