Two small parcels are planted with Gewürztraminer in the Rangen Vineyard, directly above the river Thur that runs only a few yards from the first vines. This river plays an important role in the development of noble rot and is a source of heat. The volcanic soil of the Rangen has a powerful influence on the Gewürztraminer grape. Zind-Humbrecht’s dedication to terroir expression guides all winemaking practices, which include extended pressing cycles, abbreviated clarification cycles (to retain natural yeasts and proteins in the must), natural malolactic fermentation and extended aging on the lees. The wine is aged 18 months in 40-year-old French barrels.
