The Wizard of O3: Morellino di Scansano DOCG Fattoria Mantellassi produced the first Morellino di Scansano without added sulfites with Purovino® technology. Purovino replaces the use of sulfur dioxide (a wine preservative that has several contraindications), with ozone, which, through a hyperoxygenation process, blocks the oxidation of the wine, ensuring excellent preservation of the organoleptic properties. Purovino® is a scientific-technological method aimed at producing wines without added sulfites, with particular attention to environmental sustainability and the healthiness of the final product. The MAGO DI 03 grapes are treated by saturating the atmosphere of the storage chamber with ozone for one night. The grapes thus sterilized are processed using equipment that is in turn treated with the same gas. The must thus obtained does not need to be protected with SO2, much less will there be a need to add sulfites to the wine.
