The journey to discover our vineyards in Portofino starts from one of the few unique galleries that is now home to an ecological wine cellar, while also being a study laboratory and data collection point for a renewable energy project in the territory of Portofino. The opportunity to use existing sites, war shelters and tunnels dug in the 60s, allows for the creation of the self-sufficient wine cellar for local products from Portofino.
Water-to-water heated pumps are located in the Grotto; these are capable to ensure the production of chilled water, used for cooling the cellar and for the winemaking/preservation processes of the product itself. The operation of the heated pumps exploits the drain/unloading water of the cave, guaranteeing a very high production yields, resulting in a natural occurring system, comparable to those found in geothermal systems.
