In Apulia, Fiano b. makes an excellent fish wine and also, in the higher grade and slightly sweet type, a dessert wine. In addition, especially if the grapes are harvested in time and processed as a single variety, it is an excellent basis for the production of spumante charmat method wine.
The grapes of the Fiano b. vine are today used exclusively for vinification, whereas in the past, given its good keeping qualities, it was also partly used for consumption in its fresh state.

In Apulia, it is used for the production of QWpsr Locorotondo and Martina or Martina Franca.
The wine is pale straw yellow in colour (turning golden when fermented with pomace), with a pleasant, light, special aroma. Fresh, soft and dry taste, with a slight hint of toasted hazelnuts.

The Fiano b. vine has long been present in Apulia, where it enables the production of quality wine. It is registered among the varieties suitable for cultivation throughout the region.
