Domaine Marcel Deiss

The Free Bacchus Story

Jean-Michel Deiss labels seven of his vineyards premier cru. Alsace has no such classification. The rank does not legally exist, the designation carries no standing, and he has been arguing with the authorities about it, and about permission to plant old Alsatian varieties, for years.

The argument underneath it is about how the vineyards are actually planted. Deiss inherited Schoenenbourg as an old field blend and replanted his best sites the same way: several varieties co-planted in one vineyard, ripening together, picked together and fermented together. He is firm that the results are not blends, because nothing is assembled after the fact — the mixing happens in the ground.

In 2005 he got the rules changed. The INAO reform of that year made grape-variety labelling optional for Alsace Grand Cru and permitted field blends in Altenberg de Bergheim. Deiss lobbied for it on the grounds that the existing rules described a twentieth-century labelling habit rather than the vineyards themselves.

The farming runs to about twenty-six hectares at Bergheim, certified organic through Ecocert and biodynamic through Demeter.

Whatever you make of the field-blend argument — and it is a genuine argument, not a marketing line — the farming underneath it is audited independently against two separate standards. The theory is contested. The certificates are not.
