Our Winery › Terroirs and Grands Crus
Grand Cru Rosacker – Hunawihr
Named after the wild roses growing along its border, the Grand Cru Rosacker vineyards extend to the north of Hunawihr over a surface of 26.18 Ha (64.7 acre). The vineyards face east-south-east at an altitude between 260 and 330m. The soil, a heavy, grey limestone with intertwined layers of marl (calcareous clay), is very rich in calcium and magnesium.
Sipp Mack cultivates 2.10 Ha (5.2 acre) of Riesling Grand Cru Rosacker.
Young, the Riesling Rosacker has a racy, firm temperament with a sharp, peppery aroma that mellows with age. The wines reveal full strength over time, expanding in depth, unveiling complex, yet subtle mineral flavors, which are characteristic of Rieslings from great terroirs.
Grand Cru Osterberg – Ribeauvillé
The Grand Cru Osterberg vineyards are located on the steep, sun-drenched, east-south-eastern slopes of Ribeauvillé at an altitude between 250 and 350 meters. They cover 24.60 Ha (60.8 acre) and have stony, clay-over-marl soils.
Sipp Mack’s Grand Cru Osterberg fields, around 0.84 Ha (2.1 acre), are planted in Riesling and Pinot Gris.
The Riesling Osterberg is opulent, and a touch sweeter and richer than the Grand Cru Riesling Rosacker. With age, it develops a strong body, a wonderfully subtle aroma, and an outstanding mineral character. It is a perfect wine for aging.
The Pinot Gris Osterberg is complex and powerful, with rich fruit sweetness. This richness is perfectly balanced with a good acidity, giving the wine elegance and finesse. The Pinot Gris Osterberg also may be kept for 10 years before drinking.
