The crops are highly diversified and alternate with woods that cover one sixth of the entire area.
The vineyards, though, hold sway from their vantage point on the hillsides:here since olden times and widely-planted since the early 1900’s, the varieties include Nebbiolo, which softens in the Roero, Barbera, and other rarer vines, such as Arneis and Favorita,which produce white wines with a delicate flavour and intense nose, and are becoming increasingly common.
To the left of the River Tanaro, just a few kilometres from Alba, the hills of the Roero unwind amidst a tangle of intersecting valleysand hollows in a succession of rounded knolls, with slopes that are at times gentle and at others inaccessible.
In the myriad of animal and plant fossils to be found – sometimes in extensive banks – on the sheer walls, the final stages of the Po sea and the botanics of a hotter climate than today’s can be studied.
The most important D.O.C.G. and D.O.C. wines grown in this area are Roero, Nebbiolo d’Alba and Langhe Nebbiolo,Barbera d’Alba, Roero Arneis and Langhe Favorita, as well as a dessert wine called Birbèt, covering a total surface area of approx. 3500 hectares.
Since 2014 there is a new reason for visiting the Roero hills. That reason is called Unesco: the United Nations Educational, Scientific and Cultural Organization listed the vineyard landscapes of Langhe-Roero and Monferrato as Unesco Heritage, thanks to the combined work of man and nature.
