Silex Pouilly Fume 2017 Didier Dagueneau

Tasting Notes

The nose starts with smoke and stabbed flint, a classic silex, with grapefruit skin, white peach and a salty edge underneath. On the palate, the 2017 is characterized by density. The concentration of the short vintage shows up in density rather than weight. Aging in oak barrels imparts a creamy texture that envelops the acidity. The finish is long, salty and almost chalky. Still young and intense. Needs air.

Grape Varieties

Silex is 100% Sauvignon Blanc. It is neither a blending partner nor a softener. So why is this bottle not similar in flavor to wines like Marlborough Sauvignon? The answer lies in the silex (flint) soil at the top of Saint-Andelain hill: in 2017, the yields were reduced due to April frosts, so the concentration resulted in stronger than usual smoky, salty, flinty notes.

Cellaring Potential

Best between 2025 and 2035, with the best period between 2028 and 2032. Flint soil acidity and minerals underpin this wine, and 2017 has enough concentration to keep it at 12-14°C. Expect the smoky notes to deepen with age and the fruit to take on a waxy hue.

The Producer

Didier Dagueneau changed winemaking in the Loire Valley in the 1980s when he began fermenting Sauvignon Blanc in oak barrels. Why age a crisp white wine in oak barrels? But Dagueneau took inspiration from Burgundian masters like Henri Jayer and applied their methods to the Loire terroir. Didier Dagueneau died tragically in 2008. But he worked alongside his father both in the vineyard and in the cellar, learning the philosophy behind each decision. Today, Louis-Benjamin and his sister Charlotte run the estate with an uncompromising approach: low yields, multiple hand harvesting and only indigenous yeasts. We consider them one of the most important white wine producers in France.

Terroir & Climate

The Silex vineyard is located at the top of Saint-Andelain hill, where siliceous clay mixed with limestone creates perfect drainage. But what makes this place special is the flint (silex in French). It is a mass of silica-rich rock formed millions of years ago that has a unique effect on Sauvignon Blanc. After a rain, the soil drains quickly, forcing the roots of the grapes to work harder and dig deeper. This stress concentrates the flavors and creates the mineral complexity you feel in the glass. The continental climate means cold winters and warm summers, and the Loire River mitigates temperature swings and lengthens the growing season.

Winemaking

This is where Dagueneau revolutionized winemaking on the Loire. Silex is fermented in French oak barrels rather than stainless steel tanks. The barrels are a mix of traditional 225-liter barriques and large 320-liter cigar-shaped barrels designed by Dagueneau himself. Why oak for Sauvignon Blanc? Not for vanilla flavor, but for texture and contact with oxygen during fermentation. Native yeast does the job (no commercial yeast is added) and the wine is aged on lees for 12 months without stirring. Contact with the lees creates a creamy texture that is immediately noticeable. After aging in barrels, the wine is transferred to tanks for several months before bottling. Louis-Benjamin continues to experiment with different vessels, including ceramic eggs, but oak remains the centerpiece of the Silex style.

Food Pairing

A mineral backbone and bright acidity make Silex ideal for classic wines from the Loire Valley. The local goat cheese Crottin de Chavignol is a perfect match for the wine's tingling character and citrus notes. The acidity breaks up the richness of the cheese and the mineral notes complement each other perfectly.

• Grilled sea bass with herbs
• Scallops with lemon
• Raw oysters, especially from the Muscadet region
• Asparagus with hollandaise sauce

Serve at 10-12°C to preserve the mineral precision and aromatic intensity of the wine.
