Located in Niedermorschwihr in Alsace, Domaine Zind-Humbrecht produces Riesling Sommerberg from steep granite slopes within this historic Grand Cru vineyard. The soils contribute both aromatic lift and mineral structure. Fermentation takes place with indigenous yeasts followed by ageing on lees to develop complexity while preserving freshness. The warm 2023 vintage delivered ripe fruit supported by vibrant acidity. Compared with Riesling Brand, Sommerberg often shows greater tension and minerality, combining citrus, stone fruit and floral notes with structured acidity and long, precise finish typical of steep granite vineyards. https://www.zindhumbrecht.fr
