From SelectioNaturel:

“Located roughly 40km south-east of Rome, and just over the other side of the Castelli Romani from Frascati, the family have owned and cultivated just 3 hectares of land for more than 100 years. Just 2 hectares are taken up with vineyards, with the remainder being a combination of olive groves, fruit trees, and a vegetable garden to provide for family consumption.

The vines here are upwards of forty years old, and consist of traditional varieties to the area - Sangiovese, Malvasia, and Trebbiano. They farm entirely naturally, and grapes are always hand-harvested. In the cellar, the process consists of manual pressing, native yeast fermentations without temperature control, 4 to 5 punchdowns a day, then aging only in fiberglass tanks (no oak). Rackings and bottling are done in accordance with the lunar calendar.”
