I drink red wine every single day. I reach for a Malbec, with alternatives being a Pinot Noir, a Chianti, Shiraz (Syrah), a Zin (red, as it should be), or a Cab/Merlot. Also like the Italian reds, Valpolicella and Bardolino.
My go-to table wine Malbec brand is Frontera (Concha y Toro) from Argentina and I can get a 1.5 L for about 10 bucks, sometimes less. If you should want affordable French, La Vielle Ferme aint bad at all.
If I want to move up, I like the California brand, Chateau St. Jean -- everything they put out is well done, their "Reserve" grade is even better, and better still, their spin-off line, Cinq Cepages.
Lastly, for a white, I like the Greek RETSINA. It has a taste of pine resin about it, so it's not for everybody, but I love it.
My understanding is that the hearty Malbec and Pinot Noir are highest in the phenols and bioflavenoids that make red wine so heart-healthy.
