The dairy factories: the passion for the Langa hills, the Alps in which we are immersed, the rediscovery of tastes, colours and traditions. Perla's passion in milk processing is strictly connected with the history of this remarkable territory, in order to preserve and enhance the gastronomic-cultural identity of the area where our dairy factories were founded and are linked to specific productions. All this through the defence of biodiversity of our territory and the protection of the oldest traditional products as well as those certified as PDO and in danger of extinction.
