The urge to toast sunsets in Venice’s loveliest campo is only natural – and so is the wine at Al Prosecco. This forward-thinking bar specialises in vini naturi (natural process wines) – organic, biodynamic, wild-yeast-fermented – and memorable ombre, from the signature €3.5 unfiltered ‘cloudy’ pros-ecco to the silky, €5 Veneto Venegazzú that trails across the tongue and lingers in the imagination.
