The soils of Bonnanaro are varied and range from the volcanic sand of the high hills of Mount Pelau to the calcareous and sandy soils of the gentler hills around the town. The soils of the Polinas vineyards are therefore sandy in nature on a marl base which gives the wines finesse, excellent aromas to the white wines, great color and structure to the red wines.

From the Funtana Janna vineyard, with its sandy soil, loose on a calcareous marl base, comes Vermentino, a large native white grape variety imported from Spain during the long Spanish colonization, and white Moscato with its historic clone of Bonnanaro.

In the Badde Majore vineyard we cultivate Nebbiolo, a black grape variety transplanted to Sardinia during the Kingdom of Sardinia (Sardinian-Piedmontese kingdom). The nature of the soil is mainly sandy with a fraction of clay which makes this soil suitable for structured red wines.

Cagnulari is born from the Murunis vineyard, an interesting autochthonous black grape variety that releases fantastic aromas and colours. This is a medium-textured soil, particularly fresh, suitable for vines that will give young vintage wines such as our Cagnulari.

And finally, in the sandy vineyard of Monte Santo, the most suitable wine-growing area in the Bonnanarese area, we cultivate Cannonau, a black grape variety, which according to recent studies appears to be one of the oldest vines in the world. Land greedy for water, given its nature, which forces the vine to seek water resources in depth but which will give the grapes a slight water stress which will concentrate aromas and polyphenols and the resulting wine will benefit in final quality.
