Originated from the Eocene elevation, which determined the spread of an extended zone of colluvial material around it, and marl with sandstone belonging to the “flyschoide” period that has given rise to a rocky substratum.

The foundation of the winery began in 1881 when great-great-great-grandfather Anton Jermann came to Farra d'Isonzo from Austria. Angelo Jermann, whom the 'Red Angel on the Moonlight' wine is named after, continues the family grape-growing tradition and transforms Jermann into a successful farm. In 1971, Silvio Jermann, an enology graduate, revolutionized the winery after a research sabbatical overseas, creating the Jermann milestone wine, Vintage Tunina, which was officially released in 1975, quickly achieving cult status and effectively launching Jermann's new course.
