Mumm Napa NV Cuvée M Sparkling (Napa Valley)

Tasting Methodology and Goals

All tastings reported in the Buying Guide are performed blind. Typically, products are tasted in peer-group flights of from 5–8 samples. Reviewers may know general information about a flight to provide context—vintage, variety or appellation—but never the producer or retail price of any given selection. When possible, products considered flawed or uncustomary are retasted.

Special Designations

Editors' Choice wines are those that offer excellent quality at a price above our Best Buy range, or a wine at any price with unique qualities that merit special attention.

Cellar Selections are wines deemed highly collectible and/or requiring time in a temperature-controlled wine cellar to reach their maximum potential. A Cellar Selection designation does not mean that a wine must be stored to be enjoyed, but that cellaring will probably result in a more enjoyable bottle. In general, an optimum time for cellaring will be indicated.

Best Buys are wines that offer a high level of quality in relation to price. There are no specific guidelines or formulae for determining Best Buys, but they are generally priced at $15 or less.
