Wine may be as versatile as any ingredient in the kitchen. Even for those who eschew drinking the stuff, fermented grape juice can enhance all manner of proteins, vegetables and desserts. It can work in quick sautés or hourslong braises, sauce-making or baking.
And it's a lot less complicated to choose and use in the kitchen than to figure out what to buy and drink among countless options in a restaurant or store.
Of course, there are some general guidelines:
Don't use second-rate wine. Wine is an ingredient, and a dish is generally only as strong as its weakest link. Disagreeable flavors in the wine will, of course, show up in the food. As Duxoup winemaker Andy Cutter, an Anoka native, notes, "Never use crummy wine while cooking, because all it does is cook off the alcohol, and the only thing good about crummy wine is the alcohol."
Do not buy the stuff called "cooking wine." It's invariably subpar juice, often loaded with additives. Plus you have no idea how old it is, and it actually is more expensive per ounce than a lot of decent "real" wine. Speaking of which …
Don't turn up your nose at inexpensive wine. Ever-improving boxed wines can be ideal for cooking, and an $8 to $12 bottle — or yes, Three-Buck Chuck — is a swell option if you like the wine and are good with consuming what you don't use before or during the meal. There's rarely reason to reach for more expensive wine, unless the dish calls for a half-cup or less and you want to sip away at the rest of the bottle that evening.
Stay away from wine that was opened more than a couple of days ago. Good cooks wouldn't toss in herbs that had turned brown, and calling on wine that has faded or even gone bad will not produce pleasant results. An occasional exception: If a recipe calls for red- or white-wine vinegar, you might be able to substitute the wine, but smell and taste it first.
Wine does indeed eventually turn into vinegar. That points to one of the main reasons it is such a useful culinary tool: the acidity. In fact, whites and reds with more acidity (pinot gris/grigio, Sangiovese, pinot noir) tend to work better than "bigger" wines (domestic chardonnay, petite sirah, cabernet sauvignon). They can add a jolt to richer sauces and dishes, in much the same way vinegar complements oil in a vinaigrette.
