The Verdeca b. grape is used exclusively for vinification. It is usually used in blends with Bianco d’Alessano for the production of DOC wines such as “Martina” and “Locorotondo”. The wine, excellent with fish, has a white colour tending to greenish and a neutral taste.

It is suitable for the preparation of typical wine. In the past it was widely used for the preparation of aromatised liqueur wine, the production of which then dropped.
