The Alsace climate is characterised by the alternation of warm days and cool nights during the autumn, which offers ideal conditions for the slow and gradual maturation of the grapes, concentrating the fruit flavours from the warmth of the sun, while retaining a balancing acidity from the cool nights. The Vosges Mountains act as a natural barrier, protecting the vineyard against heavy rainfall. This reduces the risk of disease and facilitates limited treatment in the vineyard. The vines are Guyot pruned and undergo a green harvest and meticulous canopy management to ensure good light penetration and air flow, resulting in healthy, concentrated berries. The grapes are hand-harvested at optimal maturity. They hold the Haute Valeur Environmentale (HVE) certification, which officially recognises the environmental performance of winegrowers, including biodiversity conservation, plant protection strategies, managed fertiliser use and water resource management.
