Terroir

• The south/south-east-facing slope of a sub-Vosges foothill, exposed from east to south-west, with a steep gradient.
• Soils of very dense marls over a limestone bedrock, well drained, ensuring a balanced water supply to the vines.
• Soils belonging to a single geo-pedological unit, associated with a favourable mesoclimate.
• The Vosges massif protects the vineyard from the cool, humid winds of the north-west.

• AOC recognised in 1992; permitted grape varieties: riesling, gewurztraminer, pinot gris and sylvaner — the only Alsatian grand cru to admit sylvaner.
• Hand-harvesting is mandatory; VT and SGN require a minimum ageing of 18 months.

• Dry wines are mineral or aromatic, fruity and full-bodied, with a golden-yellow appearance; VT (exotic aromas, candied fruit) and SGN (fruit paste) through to amber-yellow.
• Excellent ageing potential: dry wines gain complexity over time; VT/SGN are described as 'sweet wines of very long keeping ability' with 'remarkable concentration'.

• The dense marls yield powerful, rich wines with an elegant salinity and great aromatic finesse.
