Armand de Brignac Brut Gold (Jeraboam) (3 L)

The Cattier family has worked the chalky Premier Cru hillsides of Chigny-les-Roses and Rilly-la-Montagne on the Montagne de Reims since 1763 — but it was Jean-Jacques Cattier's 2006 decision to break the dominant-base-year convention entirely that defined Armand de Brignac's winemaking identity. Every Brut Gold assemblage blends exactly three distinct harvest years in deliberate equal weight, a structural commitment no major prestige house replicates at scale.

The Montagne de Reims terroir — cool-aspect chalk hillsides at Premier Cru elevation — drives the Pinot Noir backbone that anchors the 40% Pinot Noir, 40% Chardonnay, 20% Pinot Meunier blend, with Chardonnay sourced from Grand Cru villages Avize, Cramant, and Oger on the Côte des Blancs. Chalk subsoil delivers the taut mineral tension that keeps the wine's architecture intact across extended aging.

Grapes are hand-harvested and pressed on traditional vertical Coquard presses — not pneumatic membrane — selecting only the tête de cuvée first-press fraction from 4,000 kg lots. Base wines are vinified in concrete tanks to build creamy texture. The wine ages a minimum three years on lees in a dedicated gated section of the Cattier cellars, descending over 30 metres underground, followed by traditional hand riddling over approximately one month. The defining technical transgression: the dosage liqueur itself is aged one full year in new French oak barrels before addition at 9 g/L — introducing toasted brioche and vanilla complexity at the point of disgorgement rather than through barrel fermentation, a technique with no direct parallel among prestige cuvées.

This 3-litre Jeroboam format extends the lees-contact surface-to-volume ratio, slowing oxidative development and deepening autolytic complexity beyond what the standard 75cl release achieves.
