In 1982, the Mionetto family introduced autoclave fermentation by switching to the Charmat method, which allows for better preservation of the flavors and aromas of Prosecco. After an initial soft pressing and the temperature-controlled first fermentation that takes place at the facilities of our selected producers, using the Charmat method, the second fermentation takes place in autoclaves instead of individual bottles. This additional temperature-controlled fermentation is recommended for the Prosecco in order to help maintain the freshness and aroma of the grape in the bottling phase. The winemaker's job is not only to produce a high quality sparkling wine, but to maintain the relationships with local farmers who provide the grapes. Mionetto is fortunate to have relationships with vineyard owners that date back for generations. The strength and longevity of these relationships can affect the quality and quantity of grapes provided to a winery. These relationships have been passed from generation to generation at Mionetto.
