Guarnaccia Bianca is a historic grape variety from Calabria, documented in the region as early as the first half of the nineteenth century and listed in the National Register of Grape Varieties since 1970. Its origins are linked to the wine-growing tradition of southern Italy, with possible similarities and local names shared with other varieties, but its identity is now recognised primarily within the Calabrian region. From an ampelographic perspective, it produces a medium-sized, conical bunch with two or three well-developed wings and a moderately loose structure. The berries are small, spherical, with a visible navel, and a thick, firm skin covered in abundant bloom, of a greyish-yellowish colour. The leaf is medium-sized, orbicular or pentagonal, and generally three-lobed. It is mainly found in the province of Cosenza, particularly in the Pollino area and around Saracena, with some presence also in the Crotone and Catanzaro areas and other parts of Calabria. Wines made from this variety alone display a straw-yellow colour, sometimes intense, and delicate yet persistent aromas that are floral, fruity, herbaceous and mineral. On the palate, they offer freshness, balance, structure and a pleasant length. Guarnaccia Bianca is also a traditional component of Moscato di Saracena, an ancient Calabrian passito wine, to which it contributes complexity and finesse.
