Domaine Ostertag, Epfig, in the Bas-Rhin, Alsace.

André Ostertag divided his wines into three categories early on: vins de fruit, vins de pierre, vins de temps. Wines of fruit, of stone, of time. It's a way of saying that some bottlings are about the grape, some about the soil, and some about what happens after both.

The domaine has been certified organic and biodynamic since 1997. Muenchberg, the grand cru on volcanic sandstone, is the vin de pierre — the site where the soil argument is easiest to taste, and where Decanter awarded Gold.

Domaine Ostertag
Thirteen hectares across seventy-five parcels in five villages, biodynamic since 1998.

He trialled biodynamics on a single parcel before committing the estate: the 1997 trial convinced him and the whole domaine went over the following year. Testing it on one plot and then converting everything is the unglamorous version of a conversion.

Ostertag also broke with Alsace convention by using barrique for some cuvées when the region was almost exclusively neutral-vessel, which drew criticism at the time and now looks like an unremarkable choice.

At eighty dollars for a grand cru with nearly thirty years of certified farming behind it, this isn't an expensive wine by the standards of the company it keeps.

“The first wine I tasted in my life was a Sylvaner.”

Why it’s remarkable

One plot first
he trialled biodynamics on a single parcel before committing the estate
The 1997 trial convinced him and the whole domaine went over in 1998, certified by Demeter. Testing it on one plot and then converting everything is the unglamorous version of a conversion, and the one that actually tells you something.
75 parcels
across thirteen hectares in five villages
Thirteen hectares would be a single block on most estates. Split seventy-five ways across five communes, every operation has to be repeated seventy-five times, on seventy-five different soils and exposures.
Barriques
he used oak where Alsace did not, and took the criticism
Ostertag introduced barrel ageing, including new oak, for Pinot Gris at a time when Alsace worked almost exclusively in neutral vessels. He was criticised for it, and for filtering everything, which he has never hidden. It now looks unremarkable.
Fruit, stone, time
the range is split by what each wine is actually about
Vins de fruit, vins de pierre, vins de temps — wines of the grape, of the soil, and of what happens after both. Muenchberg, the grand cru on volcanic sandstone, is the vin de pierre, and the easiest place to taste the argument.
