All the suggestions in this thread are good. You'd probably also enjoy Bordeaux wines from France. These are blends based on cabernet sauvignon, merlot, and a handful of other grapes.
A handy way to get started is carry around a map of the region. http://goutaste.com/wp-content...oads/BordeauxMap.jpg
Many of the wines don't say Bordeaux on the bottle; they'll use a smaller and more prestigious place-name from within it. The areas to the left of the river are generally blends based on cab; the ones to the right of the river are usually based on merlot. All are chewy, and most will benefit from age and/or decanting.
Northern Rhone syrah might also be your wheelhouse. A wine map will also help you learn the place names here. The northern Rhone can get insanely expensive, but wines from the Crozes-Hermitage region are more everyday priced and a good introduction to the flavors here.
In the spirit of "teach a man to fish," you could do a couple things to find wines you like. (The spreadsheet is awesome!) I have a Delong Grape Varietal table at home:http://www.delongwine.com/prod...grape-varietal-table
and it organizes a couple dozen of the best-known wine grapes by weight and acidity. You could try the ones near the bottom.
Also, get on a couple mailing lists for wine ships in your area, and go to the free tastings. With winter weather coming up, they'll probably be featuring lots of chewy reds. When you're out at restaurants, you could also ask to try a splash of a by the glass wine if it's one you haven't tried before.
