Zanasi produces Lambrusco from Emilia-Romagna in Northern Italy, a region where this grape has deep roots and distinct expression. The winery's portfolio centers on Lambrusco Grasparossa di Castelvetro, the appellation's most structured variant. SassoStorno, their flagship, demonstrates the grape's capacity for complexity and dry character. La Grasparossa and Graspaoro offer further exploration of the same terroir and varietal. Lambrusco from this corner of Emilia-Romagna tends toward lower alcohol, natural effervescence, and a savory profile—qualities that distinguish it from sweeter interpretations elsewhere. The wines have been assessed by Decanter, Wine Enthusiast, and Wine Spectator.
