Bosa and its mythical vineyards are located near the sea on the west coast of Sardinia in the region of Planargia (province of Oristano). Giovanni Battista Columbu became the appellation's great figure by working for the recognition of Malvasia di Bosa and obtaining the DOC in 1972. He created the appellation's flagship estate, with a strong traditional character.
A teacher who moved to Bosa in the late 1950s, Giovanni Battista Columbu enthusiastically discovered local production and the rich cultural history of Malvasia di Bosa. With the few winegrowers faithful to this tradition of an oxidative dry white aged 'sous voile', he took an active part in the defense and recognition of this exceptional rare wine. In the heart of the small territory of the appellation (23 ha), he purchased vines in 1970 in the village of Magomadas (1.8 ha) then in 1980 in Bosa (1.6 ha), on the limestone and sandstone terroir rich in marine fossils, soils which are perfectly suited to the Malvasia grown in Sardinia. He released his first vintage in 1992. After his death in 2012, his two sons, Gianmichele and Rafael, took over the running of the family estate, continuing in their father's 'mission'.
