Capolongo B. is an ancient autochthonous wine grape variety of the Lazio region, Italy. The letter «B.» in the name indicates the white color of the berries. In some areas, including the province of Frosinone, the variety is known by the local name Reale Gialla.
At present, detailed characteristics of morphological traits, as well as detailed information on the quality of the variety's production, are not widely available. Ampelographic studies to describe the variety are being conducted by the CREA-VE center using standard OIV descriptors.
