100% Lambrusco Salamino (a particular sub-variety of Lambrusco known for thick skins, dark color, high acidity and tight bunches). Certified-organically farmed, hand-harvested fruit from 50-year-old vines, crushed and spontaneously fermented in small steel tanks. Fermentation is spontaneous and is taken to complete dryness. Secondary fermentation takes place in the bottle, initiated by the addition of fresh grape must. The bottles are hand-riddled and -disgorged. No sulfur is added at any stage of the process.
