A really high-quality, aged balsamic vinegar is something that no chef should pass up, as it is basically the standard to which all other vinegars aspire. Other vinegars have their uses, of course, but few will be coveting the taste of white vinegar to top off a nearly perfect dish. Aged balsamics can be expensive, though, and as a finishing touch to a dish or to enhance the flavor in a dressing or marinade, flavored vinegars can be great options.

Flavored vinegars are infused with everything from sweet berries to fiery chilies and they seem to be everywhere right now. Trader Joe's, for example, is carrying at least four kinds right now, including the ones pictured above: California Grapefruit, Mango Chili, Strawberry Balsamic and Pomegranate. The flavors tone down the astringency of vinegar, while retaining its brightening properties. Of the ones pictured above, Grapefruit and Pomegranate are delicious in salads, while Strawberry is good on desserts and Mango works well as a marinade.

If you can't find a flavor that matches your own tastes, you can make your own fairly easily, with fresh herbs, fruits and spices.

Apple cider vinegar is a by-product of fermented apple (hard) cider, once one of the most popular and widely available alcoholic drinks in the US. Vinegar was used for preserving foods and was common in most households, where its sweet/tart flavor found a variety of other uses in sauces and dressings. Cooks Illustrated noticed that most people tend to reach for the store brand of cider vinegar - which does not get the same amount of shelf space as trendier balsamic vinegar does - and conducted a taste test in this month's issue to see if the brand made a difference.

The vinegars were tasted plain, in barbecue sauce, in pan sauce and in a vinaigrette. Tasters tended to prefer the vinegars with a sweeter, almost honeyed taste. The top two brands were Maille Apple Cider Vinegar and Spectrum Naturals Organic Apple Cider Vinegar (unfiltered), but even very common and inexpensive brands like White House and Heinz were found to be acceptable. So while there is a difference between brands, it probably won't make or break your dish.

And as a general tip, apple ciders with little apple bits still floating in them (unfiltered vinegars) tend to be a bit sweeter, with a bit more of an apple flavor than ones that are completely clear.
