The Menti Winery was founded at the end of the 19th century in Gambellara, Italy. Today, Giovanni Menti and his son, Stefano, cultivate 7,5 ha of Garganega and Durella vines in Gambellara and Lessini. All farming is organic, using some biodynamic methods, and winemaking is very natural.
Stefano's pet-nat was produced for the first time in 2007. The Garganega is sourced from his flattest vineyards and youngest vines. After bottling, Stefano adds dried Garganega must to kick off a secondary fermentation. The wine doesn't see any sulfur added throughout fermentation or bottling. "Sui Lieviti" is Italian for "on its lees" and "Roncaie" is "forest" in the local dialect. The vineyards used to be forestland.
