At a recent Alliance Wine/H2Vin tasting I was delighted to find the wines of Jura represented by Domaine Berthet-Bondet.  Jura, tucked between Burgundy and the Swiss border, is home to one of France’s most fascinating wines: Vin Jaune. Produced exclusively from the Savagnin grape, this golden-hued wine is the result of an extraordinary winemaking process and a true reflection of the region’s terroir.

Jura’s climate isn’t for the faint of heart. Winemakers here battle heavy rainfall and the constant threat of spring frosts, making each vintage a labour of love. The region’s distinctive local varieties—Savagnin, Poulsard, and Trousseau—thrive in the marl and limestone soils, giving rise to wines with remarkable complexity. But it’s Savagnin that truly shines in Vin Jaune production.

An ancient variety, Savagnin is a genetic powerhouse. It’s the parent of some of the world’s most renowned grapes, including Pinot Noir, Chenin Blanc, Grüner Veltliner, Sauvignon Blanc, Silvaner, Trousseau, and Petit Manseng. Despite its heritage, Savagnin remains a relative rarity, thriving in Jura’s cool climate where it retains its bright acidity and rich aromatics.

What makes Vin Jaune so distinctive is its biological aging. After fermentation, the wine is transferred to old oak barrels and left untouched for a minimum of six years. During this time, a delicate layer of yeast known as voile (meaning “veil”) forms on the surface. This yeast blanket protects the wine from oxidation while contributing complex nutty, spicy, and saline flavours. The result is a wine with striking aromas of walnuts, almonds, curry spice, and dried fruit, all balanced by piercing freshness.

Due to the extended aging process, evaporation takes its toll, all that is left from one litre of wine is 62 cl which is why Vin Jaune is bottled in the distinctive clavelin, a squat 62 cl bottle.  This is also the reason why it is relatively expensive. Although quite often wine makers will bottle wines matured sous voile earlier which offer much of the character and are a little more accessible.

On the table, Vin Jaune is a great match with the local Comté cheese and works well with rich spicy food. And while it’s fascinating young, Vin Jaune is built to age, developing even more complexity over decades.

The Domaine Berthet-Bondet, Chateau Chalon 2016 was floral, chamomile, with bruised apples, bread dough notes, orange peel and nutty notes. Really complex. There is something in common with a Fino sherry but Vin Jaune is quite distinctive with more fruit at its core and of course the wines are lighter. It was dry with quite high acidity and full body, finishing with a very long nutty saline note. Amazing.
