Peter Liam, senior correspondent and critic for Wine & Spirits magazine, launched Champagneguide.net, an online guide to the wines and wine producers of the Champagne region in France.

The Web site features more than 100 Champagne houses and estates and tasting notes for more than 600 champagnes--non-vintage bruts up to expensive cuvees--on the market. Producers ranging from well-known brands to small estates are included. For those new to the language of champagne, the site offers a glossary of terms that includes familiar wine industry vocabulary and some words specific to champagne and champagne production.

The Web site is updated regularly. For more information or to sign up, visit www.champagneguide.net/registration.
