The Hermanns no longer know the exact year the first wine was produced at their vineyard. However, it is a fact that their great-grandfather Leonhard, in addition to farming, already enjoyed winemaking. Back then, around 1930, Pinot Noir was widespread in the vineyards of the Fläscher Halde. In 1975, Riesling-Sylvaner, Pinot Gris, and Completer were added. The foundation for an innovative winery had been laid.

In 1982, Peter Hermann produced his first vintage in Hinterdorf and, together with his wife Rosmarie, established the winery that exists today. The winemaking couple was always open to new ideas. They soon began experimenting with barriques in the cellar and planting additional grape varieties. Peter was the first winemaker in the Bündner Herrschaft region to produce Sauvignon Blanc.

Roman cultivates 6 hectares of vines on the Fläscher Halde. The largest plot is the terraced vineyard in Fläscher Bad, which was laid out by his grandfather Hanspeter during the land reclamation project in 1971. This historically old site is stony, steep, and steeped in history. People bathed here before the hot springs in Bad Ragaz were used.
