Heissenberg means "the hot mountain", so named for its heat-driven microclimate. It is a very steep hillside, south-facing, in the town of Nothalten. It is the very last sandstone hill before the junction point with the granitic part of the Vosges mountains, which extends to the south. The soil is composed of pink sandstone along with gneiss. It gives birth to a particularly rich Riesling, sun-tainted yet with intense minerality, balanced by the mother rock's powerful imprint.

The vines are farmed using biodynamic principles, as is all the domaine's vineyard since 1998. Heissenberg is a candidate in the current process of creating premiers crus in Alsace. This is a vineyard where only careful farming with low yields can produce interesting wines. The climatic personality of the place is so strong, that without a terroir vision, the wines result flabby and flat. But with an organic and biodynamic approach, old vines and strict yield control, the sub-soil expresses a unique, dense and structured mineral core that brings a very special balance. This is what the label shows: when sky and earth are in perfect balance through the vine, harmony comes in the wine, finishing with 13.5% alc and 4g/l residual sugar the pronounced personality of this wine requires spicy and aromatic food matches.
