Open lyre trellising

The vineyards of the Domaine des Balisiers look like no others in Switzerland. Its 25 hectares are equipped with upright two-pronged trellises: the so-called open lyre.

The open lyre trellis was invented in 1976 by Professor Alain Carbonneau of France’s Bordeaux-based National Institute for Agronomic Research. Its original lyre-shaped design doubles each vine’s exposure to sunlight and thereby enhances the photosynthetic capacity of its leaves. This, in turn, increases the precociousness and kinetics of the formation of aromas in the grapes, improving the aromatic potential of the wine accordingly.
