With almost 2,000 years of history behind it, Nikolaihof is the oldest winery in Austria, and one of the first in the world to have begun working by biodynamic principles according to the regulations of the Demeter Association. The principle: Imbue the wine with as much strength and energy as possible, whilst leaving nature to its own devices as far as possible. No herbicides, fertilisers, pestizides or synthetic sprays are used in the vineyards. Instead, the Saahs family uses stinging nettle manure, valerian drops, horse tail tea and its own specially produced homeopathic-style preparations. The grapes are harvested by hand and are fermented without artificial yeast. The estate has been owned by the Saahs family since 1894.
