Krug produces champagne in France's Champagne region, where chalk soils and cool climate shape wines of precision and depth. The house works across the region's three principal varieties: Chardonnay, Pinot Noir, and Pinot Meunier. Clos du Mesnil, a single-varietal Chardonnay, represents the upper tier of the portfolio, as does Clos d'Ambonnay, built on Pinot Noir. The Collection blend—a marriage of all three varieties—anchors the core range. Wine Spectator, Decanter, Wine Enthusiast, and Wine Advocate have all assessed the winery's output. Champagne's terroir demands patience and technical mastery; Krug's wines reflect both.
