 Such is the case with the wine Oltrepò Pavese Bonarda DOC which contains from 85% to 100% Croatina (under its local name of ‘Bonarda’).However Croatina is often blended with Barbera, as in Gutturnio, a wine from Emilia-Romagna containing 30.0% – 45.0% Croatina.It may also be employed as a very minor part of a blend, as is the case with some examples of Amarone.
