Dorona is a white wine grape native to Italy where it is found in the Veneto. Historically it was often viewed as a table grape, perhaps due to its big, round, juicy berries.
Where grown: Veneto: today the only important Dorona vineyard is currently found on Mazzorbo (one of the islands of the Lagoon of Venice), in the Bisol family estate (the wine is called Venissa).
Characteristics: Morphologically, Dorona looks very much like an opulent Garganega, with bigger berries and bunches. It is vigorous and produces constant and abundant yields; it is also resistant to fungal diseases (in particular botrytis).
Wine style: Dorona produces light, crisp white wines not dissimilar to those made with the above-mentioned Garganega.
