Château Grand Mayne – The Power of the Saint-Émilion Limestone Plateau

A Grand Cru shaped by parcel precision and vibrant mineral depth

Located on the western slope of Saint-Émilion, Château Grand Mayne stands among the estates whose identity is rooted in the expressive power of limestone. Long recognised for a generous and classic style, the property is now entering a new era, driven by a more precise, geological and terroir-focused vision.

At the heart of this transformation lies a strong commitment to parcel-by-parcel mastery, sustainable farming, and the pursuit of a pure, mineral balance deeply faithful to the magic of the Saint-Émilion plateau.

Terroir – The Strength of Limestone

The 17-hectare vineyard sits on one of the most prized geological formations of the appellation: asteriated limestone covered with deep clay, the hallmark of the greatest Right Bank wines built for long ageing.

Key characteristics:

• Limestone and clay-limestone soils with excellent water regulation;
• slopes and foothills ensuring natural drainage and gradual ripening;
• temperate microclimate promoting freshness and balance;
• old parcels where Merlot reaches exceptional nobility.

This mineral-driven terroir yields wines combining density, tension and inner vibrancy—the signature of the most refined Saint-Émilion crus.

Grape Varieties

• 67% Merlot – flesh, velvety texture, aromatic depth;
• 25% Cabernet Franc – tension, floral energy, vertical structure;
• 8% Cabernet Sauvignon – backbone, length, complexity.

Each variety is planted according to a strict terroir logic: Merlot on richer clays, Cabernet Franc on draining limestone zones, Cabernet Sauvignon on the warmest slopes.

Viticulture – Parcel Precision & Living Soils

The estate implements an exacting viticultural approach, combining close observation and sustainable practices:

• hand harvesting only;
• strict parcel selection at picking;
• thoughtful cover cropping adapted to each soil;
• minimal intervention to encourage biodiversity;
• parcel-by-parcel management for every block.

The goal is clear: reveal the identity of each micro-parcel and express the natural limestone minerality without embellishment.

Winemaking – Precision, Purity & Finesse

Each parcel is vinified separately in thermoregulated stainless-steel tanks. The technical approach favours delicacy and clarity:

• cold maceration depending on the vintage;
• 3 to 4-week vatting times;
• gentle extractions for fine, polished tannins;
• measured use of new oak (about 40%);
• 16 to 18 months ageing in selected French barrels.

The aim remains constant: producing wines that are structured yet luminous, powerful yet guided by mineral purity.

Wine Style

Wines from Château Grand Mayne stand out for:

• deep, precise dark-fruit expression;
• saline limestone freshness;
• silky, noble tannins;
• a distinctive vertical energy;
• a long, refined and persistent finish.

It is a decidedly modern vision of Saint-Émilion: elegant, balanced, pure and built for ageing, yet already charming in youth.
