Also known as Vignarionda, Vigna Riunda, Arionda or Rotonda, due to the rounded shape of the hill where it is located, it occupies the central part of the hill ridge of the municipality of Serralunga d’Alba.
As in many other areas of the Langa, the soil contains a lot of limestone. We are in the Lequio Formation, made up primarily of clayey marl and, to a lesser extent, sand. The stratification of the soil originates from the geological conformation of the area, which is of sedimentary and marine origin.
Millions of years ago, these hills were a seabed.
The combination of geological characteristics, favourable exposure and a supportive microclimate all contribute to making the grapes that grow in the Vigna Rionda particularly expressive.
