It’s obvious to most people that red wines pair well with steak, but what may not be obvious is that not all red wines are a perfect match. In a consolidated effort to get this right for our readers we opened a LOT of red wines and cooked quite a few steaks to write this week’s round up. When it comes to wine and food pairings, Cabernet Sauvignon and grilled steaks are the ultimate partnership, but it is not the only one. Red wine and well-marbled beef work together thanks to compounds that merge in our mouths when we combine them, in particular, protein, fat, and tannins.

There’s always an element of chemistry to consider; tannins, which are compounds in wine present in grape seeds, grape skins, and oak barrels, offer a drying or astringent quality on the tongue and gums. Steak’s natural levels of fat and protein provide a lubricating or moist feeling in the mouth. When steak and red wine get together, the astringent and moist qualities strike a balance and create an enjoyable sensation. Then science kicks in, with molecules in the steak’s fat making the tannins more pliable, producing softer, smoother sensations, while the wine’s tannins mellow out the fat and coax more flavor out of the meat. Ripe Napa Valley Cabernet Sauvignon with bold fruit flavors and a good amount of oak aging is an excellent mate for well-marbled, grilled beef, but other wines with bold tannic structure such as , , blends, and Sicilian wines made from indigenous Nerello Mascalese grapes grown on the volcanic soils of Mount Etna also match extremely well. We did a lot of homework, so you don’t have to; here are the best red wines to pair with steak.
