Castelnau bottles Champagne from the classic trio — Pinot Meunier, Pinot Noir, and Chardonnay — with several cuvées built on a solera reserve (the ES 9.0 and ES 9.1 Origine bottlings). The range runs from a Brut Champagne Premier Cru up to the Veloce Cuvée 10 Ans and the Millésime tier. Four prestige critics — Decanter, Wine Spectator, Wine Advocate, and Falstaff — rate the wines across vintages, with scores clustering between high 80s and low 90s on the prestige cuvées. The Demi-Sec sits in the lineup for anyone who wants Champagne with dessert on its own terms.
