This is a delicious, brut-style wine, based on Chardonnay and Pinot Noir. It's very rich in strawberry, raspberry and lime flavors, with vanilla and toast complexities, and the finish is honey-sweet and spicy. Great price for a bubbly this elegant.

Among the more successful sparklers that are clearly biased to sweetness and one that fully delivers on the yeasty promise of the method champenoise, the latest Cuvée M from Mumm is forthrightly fruity and sports a fine sense of creamy richness. It is foamy and friendly but shows a somewhat more serious side, and it is so well-balanced by enlivening acidity that it never once seems sugary in character.
