Filo di Seta is a unique Brunello that is the result of a rigorous selection of grapes harvested by hand near the Castello Romitorio. Filo di Seta, which translates as Silk Thread, is the name of a creek that flows through the forest nearby.

Fermentation takes place in stainless steel tanks with an initial short period of cold maceration (below 20°C) on the skins for about 15-20 hours. This is followed by up to 20 days of maceration at a higher controlled temperature.

Malolactic fermentation that is naturally caused then lasts for about 10 days, before the wine is rested to separate the lees. The wine matures in oak for approximately 30 months, and after bottling the wine is aged in Castello Romitorio’s temperature-controlled cellars for an approximately 12 months before release.
