Last verified · August 2026
The Kastelberg slope at Andlau — schist, steep, and worked by hand.

In 1985 Marc Kreydenweiss met François Bouchet, one of the small number of people carrying biodynamics into French viticulture at the time. He converted the estate in 1989, working alongside his eldest son. Alsace then had almost no biodynamic wine trade to convert into.

He had taken the domaine over from his father in 1971, which puts the decision eighteen years into a conventional career rather than at the start of an idealistic one. The estate works four grands crus — Kastelberg, Wiebelsberg, Moenchberg and Kirchberg de Barr — and it is the first of those that the domaine is judged on.

Domaine Marc Kreydenweiss
Marc Kreydenweiss converted the estate to biodynamics in 1989.

Kastelberg is black Steige schist, a soil found nowhere else in Alsace, laid down somewhere between 350 and 400 million years ago. The slope above Andlau is steep enough that the work has to be done by hand. Almost nothing else in the region grows on rock that old.

In 1999 the family took the method south, when Marc's son Jean started a second biodynamic domaine in the Costières de Nîmes. Certification in Alsace is Ecocert under EU control code FR-BIO-01, with Biodyvin membership covering the entire estate rather than a selected parcel.

Converting in 1989 bought nothing. There was no premium to charge, no shelf category to occupy and no press waiting to write it up. Whatever the reason was, it was not positioning.

Why it’s remarkable

1989
converted before there was a market
Alsace had almost no biodynamic wine trade in 1989. Kreydenweiss converted anyway, four years after meeting François Bouchet, and became one of the region's first.
1971
when he took the estate from his father
Eighteen years of conventional farming came before the conversion. The change was a decision made mid-career, not an inheritance.
Kastelberg
one of the oldest planted slopes in Alsace
Schist, steep enough to need hand work, and the source of the Riesling the domaine is judged on.
