Les Crêtes operates in Valle d'Aosta, Italy's smallest wine region, where Alpine elevation and cool continental conditions shape a distinctive terroir. The winery produces wines across multiple varietals, anchored by three standout expressions: Neige d'Or, Prëmetta Spumante (made from the local Premetta grape), and Merlot Le Merle. Each has earned recognition from major critics including Wine Spectator, Wine Advocate, Wine Enthusiast, Decanter, and Falstaff. Valle d'Aosta's high-altitude vineyards yield wines marked by crisp acidity and mineral precision—characteristics that define the region's identity. The winery's portfolio reflects both international varietals and indigenous grapes, drawing on the Alpine microclimate that distinguishes this corner of northern Italy.
