The vines at Ribelà range from 30-60 years old, with a tiny parcel planted on un-grafted, piedi franco rootstock.  They are located at 350+ meters of altitude, the highest in the Frascati/Castelli Romani DOC. Soils are a unique mix of volcanic basalt, sand, clay and limestone; something you only find high on the hillside of Frascati.  Farming is combination of holistic Biodynamic and natural, non-intervention practices.  The grape varieties are those traditional in this part of Lazio; Malvasia, Trebbiano, Bombino Bianco, Bellone, Cesanese, Aleatico and Montepulciano.
The winemaking is rigorously natural in approach, with respect for the regions traditions as well as a "modern" understanding of natural farming and winemaking without any additives.  No yeast, no sulfur...just grapes and intuition.
