Cuvée Robert Fleury Champagne

Barrel-fermented, biodynamic blend of Chardonnay, Pinot Blanc and Pinot Noir. Crisp, with a dominant flavor of apples. Good body and acidity; medium bubbles.  Overall nice, but not really a standout.  The Fleury Brut Rosé Champagne, at a comparable price, is a more compelling choice from this producer.

Jacob's Creek Brut Cuvée

Via Eric:

Ah, the Aussies! They're a hardy lot, and they can turn out some decent Sparkling wines to boot! One of my favorites from the Land-Down-Under is Jacob's Creek, Chardonnay Pinot Noir Brut Cuvée. Very reasonably priced, and very enjoyable (~$15). It's balanced in all respects: Dry, but not overly so; Flavorful, but not too yeasty; Full of Bubble, but in a relatively refined way.

Domaine J. Laurens Brut NV

Via Eric:

Had dinner at Greens Restaurant in San Fran's Marina district recently. For Aperitif they had the Domaine J. Laurens Brut NV, Cremant de Limoux, France. Found it Lemony/Citrus on the palate, but with a not altogether-pleasant chemical aftertaste. Wouldn't recommend it.
