Gringet

Gringet. Gringet is a rare white wine grape variety indigenous to the Savoie wine region of eastern France, most notably cultivated in the Ayze area of Haute-Savoie. Long mistaken for a local clone of the more widespread Savagnin, DNA profiling has confirmed its distinct genetic identity, making it a viticultural treasure of the Alps. The grape is prized for producing distinctive, high-acid sparkling wines under the Vin de Savoie AOC, as well as still wines of notable minerality and longevity.

History

The historical origins of Gringet are obscure, with its cultivation likely centered for centuries in the steep, glacial valleys around Ayze. For generations, local vignerons and ampelographers assumed it was a biotype of Savagnin, a variety famous in the Jura region. This misconception persisted until the early 21st century, when researchers at Domaine Belluard and analyses by the Institut Français de la Vigne et du Vin conducted definitive DNA analysis. The results, published around 2009, revealed no genetic relationship to Savagnin, establishing Gringet as a unique cultivar. Its survival is attributed to the isolation of the Alps and the dedication of a handful of producers, most notably Dominique Belluard, who championed its potential and fought for its recognition within the Vin de Savoie AOC regulations.

Viticulture and winemaking

Gringet is a late-ripening variety, well-suited to the cool, continental climate and high-altitude, south-facing slopes of its alpine home. The vines are vigorous and productive, but require careful canopy management to ensure proper ripening. They demonstrate good resistance to winter frosts but can be susceptible to fungal diseases like powdery mildew. In the vineyard, traditional practices such as gobelet pruning are often employed. In the cellar, winemaking approaches vary; for the traditional sparkling Vin de Savoie-Ayze méthode traditionnelle, the base wine undergoes a secondary fermentation in bottle. For still wines, fermentation may occur in stainless steel tanks, old oak barrels, or even concrete eggs, with many producers favoring minimal intervention to express the grape's pure, terroir-driven character. Malolactic fermentation is often prevented to preserve its razor-sharp acidity.

Wine regions

The heartland of Gringet is exclusively the Ayze district, a village nestled in the Arve valley near Bonneville in Haute-Savoie. This area holds its own dedicated appellation within the broader Vin de Savoie AOC for sparkling wines produced primarily from Gringet. The vineyards are planted on steep, well-drained slopes composed of glacial moraines and limestone-rich soils, which contribute to the wine's pronounced minerality. While minute plantings may exist elsewhere in Savoie, Ayze remains its epicenter. The total planted area is exceedingly small, likely less than 30 hectares globally, with the majority controlled by a few key estates such as Domaine Belluard, Domaine des Ardoisières, and the local Cave de l'Ayze cooperative.

Wine style and characteristics

Wines produced from Gringet are celebrated for their intense acidity, pronounced structure, and marked minerality, often evoking flavors of green apple, quince, white pepper, crushed flint, and alpine herbs. The traditional sparkling expression, labeled Vin de Savoie-Ayze, is typically bone-dry, finely beaded, and remarkably crisp, offering a vibrant and refreshing profile. Still versions, which are increasingly crafted, can be powerful and age-worthy, developing complex notes of honey, beeswax, and dried fruits over time, while retaining a firm acidic backbone. These wines are considered excellent companions to the rich local cuisine of Savoie, such as fondue, raclette, and freshwater fish from Lake Geneva.

Synonyms

Due to its long history of mistaken identity, Gringet has been known under several incorrect synonyms. The most common historical misnomer was Savagnin Blanc, referring to the Jura variety. It has also been locally called **Gringet de Savoie** and, erroneously, **Roussette** (which correctly refers to the Altesse grape). Following official DNA identification, these synonyms are now considered obsolete in ampelographic literature.
