My wine philosophy has always been this: I would rather try a new wine that I end up not liking than the same old wine I had last week.To me, there's a diminishing return to opening the restaurant wine list and ordering the same old chardonnay or sauvignon blanc again. So be bold. If you want a white wine, why not try one from the airen grape? Or an unexpected blend of chardonnay, riesling and moscato?Here's a list of some relatively unusual wines, and a bit of information about them. Highly recommended:2010 Treana White Blend, Central Coast, California (50 percent marsanne, 50 percent viognier): Marsanne is called the "white workhorse" grape of Rhone wines. It's hardy, and it makes a full-bodied, fruity wine that's popular to blend with other white varietals. Viognier is more rare, being hard to grow, but highly prized for its exotic aromas and flavors -- vanilla, peaches, mangoes. At its best in the Condrieu region in France's Southern Rhone Valley, it's growing fast now in California. Treana White is intensely aromatic, with hints of camellias and honey and flavors of tropical fruit. It's crisp enough to go well with rich foods. $21. Recommended:2011 Kendall-Jackson "Vintner's Reserve" Sauvignon Blanc, California (88.8 percent sauvignon blanc, 9 percent semillon, 1 percent pinot gris, 0.5 percent riesling, 0.4 percent chardonnay, 0.3 percent viognier): Rich and fruity, it has a variety of flavors, from lemons and pineapples to pears and honey. Sure, it's mostly good old sauvignon blanc, and it might be easy to pooh-pooh the addition of tiny dollops like the 0.3 percent viognier. But I've seen winemakers do it, and I can attest that it can make a real difference in the flavor. $13.2011 Apothic White Wine, by Apothic Wines, California (chardonnay, riesling, moscato): This is a United Nations of a wine, with grapes associated with France, Germany and Italy -- all grown in California. As you might expect, it's rich and complex, with aromas and flavors of pineapples, green apples and honey. it would go well with all the white wine foods in a buffet. $14.2011 Tangent Wines Grenache Blanc, Edna Valley, California: The grape, while white, is a mutation of the red grenache grape, probably from northern Spain, but now most popular as a blending grape in France's Southern Rhone Valley in white versions of Chateauneuf-du-Pape. It's full-bodied and crisp, with flavors of tangerines, peaches and minerals. It would go well with white meat dishes and spicy food. $17.Nonvintage Cachette Blanc de Blanc Sparkling Wine from Burgundy, France (100 percent airen grapes): The light-skinned airen grape grew to fame making brandy in Spain, and now it has been adopted, thanks to its lean crispness, for making sparkling wine in France. They don't call it champagne even in France, because it isn't made in that country's Champagne district. It has lots of big bubbles and flavors of apricots and minerals. $15.
