The modern winemaking cellar in Montalcino, covering some 1,000 square metres, is built almost entirely underground. The harvested grapes are conveyed by gravity from the roof, beginning the itinerary that will bring the berries inside the cellar and into new stainless steel tanks for the initial fermentation at 29°-31°C. A controlled temperature is absolutely essential for the protection of the yeasts present on the grape skins at the time of harvest. The tanks are equipped with automatic pumpover systems that can be programmed in cycles that will ensure maximum extraction of compounds from the skins. Maceration on the skins is one of the most critical steps in the winemaking process, since the compounds that will later determine the aromas and flavours are extracted during this process.
