Robert et Marcel De Chanceny Crémant de la Loire Brut ($15.99)

FOOD MATCH: As a celebratory glass, this tasty and well-balanced bubbly is fine for sipping on its own. It will go just about anywhere that a food-friendly white will go, though, from chicken, pork or veal to all manner of cheese.
WHEN TO DRINK: It's not made for aging, but it certainly won't die if you hang on to it over the next year or two.
VALUE:
The combination of Loire grapes and the traditional process makes this a remarkable value in competition with Champagne prices.

Broadbent Madeira Reserve 5 Years Old Fine Rich ($24.99)

FOOD MATCH: This fine dessert and after-dinner wine is made for drinking on its own too, but it matches well with snacks that match its deep flavors: Walnuts and pecans, blue or creamy cheeses, even dark chocolate. We've also enjoyed it with French onion soup.
WHEN TO DRINK: Madeira is essentially ageless, so you can keep it almost indefinitely, even in an opened bottle.
VALUE:
It's a very good value at my local price, which matches Wine-Searcher.com's $25 average U.S. retail.
