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.

Ratings reflect what our editors felt about a particular product. Beyond the rating, we encourage you to read the accompanying tasting note to learn about a product’s special characteristics.
