Deutz's Hommage a William Deutz line is the house's creative playground, a pair of single-vineyard prestige cuvees that honor the founder by spotlighting the kind of terroir-specific Champagne that the great houses rarely bottle on their own. La Cote Glaciere is 100% Pinot Noir from a 1.9-hectare south-facing plot in Ay, planted in 1967, with chalk just 70 cm beneath the surface. The 2018 was harvested early to preserve freshness, and the result is opulent and generous but laser-focused, with the chalk underpinning everything. Limited production from one of Champagne's most quietly serious houses.
