Champagne R.H. Coutier is a historic grower-producer estate rooted in the Grand Cru village of Ambonnay since 1619. Now led by fifth-generation winemaker Antoine Coutier, the house gained acclaim after Antoine’s grandfather became the first grower in the Pinot Noir-dominated village to plant Chardonnay in the late 1940s. The estate farms roughly nine hectares divided across 40 distinct Grand Cru plots exclusively within Ambonnay, where vines average 38 years of age.

For the Extra Brut Millésime 2015, fruit is sourced from these south- and southeast-facing parcels, which benefit from a warm microclimate and clay-rich chalky limestone soils. Produced only in standout harvests, this vintage cuvée reflects the estate's organically farmed terroir through a marriage of Ambonnay's rich Pinot Noir (75%) and crisp, mineral-driven Chardonnay (25%).
