If you liked that bordeaux, you may like other blends, such as California meritage. As for other "drinkable" wines - by which I mean one you can enjoy by itself without food if that's what you want - include Argentine malbecs, Spanish tempranillos and Chilean carmeneres, as well as pinot noirs and merlots. You can also find some nice Italian reds, though chiantis can be hit-and-miss, with some smooth and others too bold. I'm presently looking at a bottle of Colosi Nero D'Avola from Sicily, which at $16 is a great choice too. Of course the king of reds is cabernet sauvignon, but these might be too "big" without a steak, or at least a bit of cheese.
As for whites - well, let your wife pick these.
