NV Medici Ermete Solo Reggiano Secco ($18)
Flavorful, crisp artisanal Lambrusco—not sugary Riunite—is terrific with food. Another pick: NV Lini Labrusca ($15).

Top-quality Muscadet, like this fragrant, zesty bottling, costs next to nothing and goes with just about everything.
2009 Lioco Sonoma County Chardonnay ($20)
Sommeliers like Kevin O'Connor (formerly of Spago Beverly Hills) are busy drinking wines they made themselves.
2008 Clos des Fées Côtes du Roussillon Les Sorcières ($22)
The Côtes du Roussillon in southern France is a sommeliers' secret for robust, Grenache-based reds that go amazingly well with roast meats.
2008 Quattro Mani [toh-kai] ($12)
Slovenia is still a sommeliers' darling, and this flamboyant white from winemaker Ales Kristancic is an excellent introduction.
2008 Marco Felluga Molamatta ($21)

NV Pierre Gimonnet & Fils Selection Belles Annees Brut ($37)
It's rare to find a sommelier without a glass of Champagne nearby. These days, that's usually grower Champagne, i.e. from small producers like Gimonnet that own their own vineyards.
2007 Les Halos de Jupiter Côtes du Rhône ($21)
When sommeliers can't find a wine they'd like to drink, sometimes they import bottles themselves. Daniel Johnnes imports Rhône winemaker Philippe Cambie's Halos de Jupiter.
2007 Louis Jadot Gevrey Chambertin 1er Cru Clos Saint Jacques ($125)
The 2007 Burgundy vintage isn't particularly ripe, which may be why top sommeliers like it: The wines have a lean, vivid raciness that makes them especially good with food.
2008 Abbazia di Novacella Kerner ($27)
Kerner is a lovely, aromatic white grape that a German viticulturist bred back in the 1960s by crossing Riesling with Schiava Grossa, an obscure red variety.
2003 Gravner Breg ($120)
Josko Gravner of Italy's Friuli region ferments and ages this inimitable, exotic white in huge terracotta pots.
