Biodynamic, no sulphites. The grapes are macerated for 10 days on their skins. It is also a natural refermentation in bottle to produce a dry, frizzante wine, and is unfiltered. Because they are not in one of the delineated zones for DOC Lambrusco, the wine is simply vino da tavola. Like the La Querciola, the Sottobosco is unfiltered and may have some sediment.
