Alpine Elixirs: Unveiling Aosta Valley’s High Elevation Wines at Rosset Terroir

Alpine Elixirs: Unveiling Aosta Valley’s High Elevation Wines at Rosset Terroir.

Many wine enthusiasts carry an inborn fascination for wines from high elevation vineyards. That is not only because of the mind-blowing idea of grapes growing at great heights. At higher altitudes the diurnal range is higher, contributing preservation of natural freshness and grape own aromas. Higher elevation wines do contain natural freshness and tension. Thinking of high-altitude wines, production area’s like Salta in Argentina or Elqui in Chile easily come to the mind. But let us not forget about Europe. This summer we visited Europe’s highest wine production area: the Italian Aosta Valley. In a spectacular alpine setting we attended the advanced Aostian winery Rosset Terroir. In this article we take you to the characteristic mountainous Valle d’Aosta.

About the Region

“Aosta Valley: Europe’s Lofty Vineyards and the Legacy of Bilingual Terroir”

The Aosta Valley is a situated in the most north eastern corner of Italy. Shaped by the river Dora Baltea, the valley lies at the foot of Europe’s highest mountain: Mont Blanc. Surrounded by the Alps highest peaks, Aosta is home to Europe’s highest vineyards. Vineyards in Aosta are mostly located at south facing steep slopes, with altitudes easily reaching towards 1,000 meters above sea level or even higher. The soils are mainly rocky and alluvial, with soil types like slate, granite and quartz.

In these extreme mountainous circumstances, it is where lovers of pure and unconventional wines will indulge themselves. In this smallest wine production area of Italy – 50 produces do cultivate 650 hectares of vineyards – one would find wines of indigenous grapes with crystalline precision. Although the Aosta Valley since 1861 officially belongs to Italy, it has a strong historical connection to France. For a long period of time Aosta was part of the Kingdom of Burgundy. The region still is bilingual – they speak Italian and French – and next to native varieties like Petit Arvine and Cornalin one will find French species like Chardonnay and Pinot Noir.

Despite the alpine position, located at the south side of the Alps the Aosta Valley is blessed with a high amount of sunshine and relatively low rainfall. Whereas in the past winemakers struggled ripening the grapes, due to changing climatic circumstances ripening nowadays is not an issue anymore. Due to the tough viticultural circumstances and necessarily manual cultivation, it is easy to imagine the natural Aostian focus on quality over quantity. Although the wines are mainly sold in Italy itself, during our visit we noticed an increased external curiosity. The recently established Consorzio Vini Valle d’Aosta is endeavouring catching the attention of the international wine market.

About the Winery

“From Roman Ruins to Alpine Excellence: The Evolution of Rosset Terroir Winery”

Based in a modern state of the art winery, Rosset Terroir has an agricultural history. For decades it has cultivated agricultural products like raspberry, genepy and saffron, intended for local liqueurs. By the turn to the 20th century Rosset started its own distillery called Saint Roch. From this place build on a formal Roman ruin, by the turn of the millennium Cesare and Nicola Rosset decided to plant vines. That decision would mark the beginning of a successful alpine wine story called Rosset Terroir.

Where the Rosset family started planting two hectares of Chardonnay, Syrah and Cornalin in Saint-Christophe, nowadays the production of 12 hectares is spread out over production areas in Saint-Christophe, Villeneuve and Chambave. Chambave is home of Moscato Bianco, whereas Chardonnay, Cornalin and Petit Rouge are planted in Saint-Cristophe. Ranging from 800 meters above sea level (Chambave) to 1.000 meters above sea level (Villeneuve) the altitude of all of the vineyards of Rosset Terroir is dazzling.

Directed by oenologist Matteo Moretto and accompanied by Carole Bich Rosset Terroir nowadays produces about 55.000 bottles of wine. In the modern and clean winery, one will find a high amount of stainless-steel fermentation tanks and some amphora and Orcio Toscano. In the cellar new and used barriques (225 litres), tino’s (2.000 litres) and tonneaux (5.000 litres) can be found, intended for aging the top cuvees. In 2019 Rosset Terroir was awarded with a Tastevin AIS award and in 2021 their Sopraquota 900 was awarded as ‘Best Italian White Wine’ by Gambero Rosso. The conversion to organic certification will be completed soon.

Conclusion

Rosset Terroir impressed us with a very good impression of the potential of the Aosta Valley. The high-quality wines from both international as indigenous varieties did leave us the impression of the beauty of the high peaks of the Alps. Wines from high elevation vineyards were as crisp and precise as fresh bottled glacier water. Considering the growing conditions, we foresee a bright future for Aosta. Aosta features possibilities to adapt to rising temperatures and keep on making crisp wines. All in all, we believe the Aosta Valley is a wine growing area to keep an eye on.
