Cantina Valle Isarco 2023 Kerner Eisacktal, Südtirol

750ml bottle

13.5% abv

Aromas of lime leaf and juicy lime segments mingle with a hint of pink salt and crushed rock. The palate is energized by rocket-like acidity and a tart, vibrant character. This Kerner from Valle Isarco delivers a zippy finish with a crisp, textured profile, capturing the essence of its high-altitude, mineral-rich terroir.

The winemaker's own notes for the 2023 are verified and specific. Entry below — I'm treating those as the tasting notes paragraph since they're from the producer's own technical sheet.

Straw yellow with greenish hues. Aromatic on the nose, with a light Muscat note, peach, and apricot. Fresh, spiced, and intense on the palate, with well-balanced acidity throughout. Dry, with 2.9 g/l residual sugar. — Cantina Valle Isarco winemaker notes, 2023

100% Kerner. A crossing of Trollinger and Riesling developed in Germany, introduced to the Valle Isarco around 1900 and now cultivated almost exclusively in this valley within Alto Adige.

Vineyard: Vineyards in the communes of Chiusa, Velturno, Bressanone, Funes, and Renon at 650–970m above sea level. South and southeast-facing exposures on stony, lean, skeleton-rich alluvial soils containing diorite and quartz phyllite. Guyot-trained. Harvest beginning of October.

Method: Delicate pressing and crushing. Controlled-temperature fermentation and aging on fine lees in stainless steel tanks. No malolactic fermentation. Bottled with minimal sulfur.

Cantina Valle Isarco — known in German as Kellerei Eisacktal — is a cooperative winery based in Chiusa (Klausen), founded in 1961 and now counting approximately 130 grower-members farming some of the most extreme white-wine terroir in Italy. The Eisack Valley (Valle Isarco) runs north from Bolzano toward the Brenner Pass and the Austrian border — a narrow Alpine corridor where the combination of high elevation, significant diurnal temperature swings, poor soils, and late harvest dates produces white wines of unusual precision and aromatic intensity. The valley accounts for less than 3% of Alto Adige's total production, making it one of the smallest and least-known DOC zones in the region.

Kerner is the signature grape here. Planted at elevations that would make most Italian white wine producers uncomfortable, it retains its acidity even through warm growing seasons and produces wines that are simultaneously aromatic and taut. The cantina works with a dedicated agronomist and oenologist team, operating with controlled yields and minimal cellar intervention. New winemaker Stefan Donà took over in 2023. This is a reliable, well-priced entry point to a valley that remains underappreciated relative to the quality it consistently delivers.
