Blanc de Morgex et de La Salle

The highest vineyards in Europe, climbing up to 1,200 metres near Mont Blanc. This is the home of Prié Blanc, a grape that completes its entire vegetative cycle in a short sprint to avoid the snow.

The Terroir Because phylloxera cannot survive in these high-altitude, sandy soils, these vines are ungrafted (piede franco). The vines are trained on low pergolas just inches off the ground to absorb the heat reflected from the rocky soil during the day and to be blanketed by insulating snow in the winter. The south-facing terraces of the Valdigne valley — the upper Aosta Valley — act as a solar trap, allowing ripeness that altitude would otherwise make impossible.

Prié Blanc The grape is found essentially nowhere else and is unusually well documented for something this obscure: DNA work places it as an offspring of Rouge du Pays, one of the old Valais varieties, which fits its position on the Swiss side of the watershed. What matters practically is its timing. It buds late enough to dodge most spring frost and ripens early enough to be picked before the first snow, compressing an entire vegetative cycle into a window that would defeat any other vinifera. Sugar accumulation stays modest and acidity stays high, which is why the wines rarely exceed 11.5% and taste as taut as they do.

Working the Slope The vineyards are terraced to gradients that make mechanisation impossible, and much of the work is done kneeling, since the pergolas sit barely a metre off the ground. Total production is minute — the appellation covers something in the order of 20 hectares across two communes — and the great majority of it passes through the cooperative at Morgex, one of the few places in Italy where a co-op is not the volume option but the only option. Growers here typically farm a few rows alongside another job entirely.

The Critical Take The wine is piercingly acidic, steely, and herbal — a liquid translation of glacier water. In still form it delivers white flowers, Alpine herbs, green apple, and a wet-stone mineral finish. The cooperative also produces a traditional-method sparkling and a rare ice wine (Chaudelune) from frozen grapes harvested in January — a unique regional curiosity.

At the Table Alpine and simple: freshwater trout, Alpine cheeses in their younger forms, cured Valdostana meats, and the fondue-adjacent cooking of the valley — though the acidity handles fat better than it handles heavy sauce. The sparkling version is a genuinely good aperitivo and the more interesting of the two. Serve at 8–10°C, and drink young; this is not a wine that rewards patience.
