The Impigno grape is a little-known, ancient white variety native to the Apulia (Puglia). Although its precise origin remains uncertain, many believe it may have first appeared in the Tarantino area, particularly around Martina Franca, before making its way to the province of Brindisi, where it is primarily cultivated today.
Local tradition holds that the name Impigno derives from the surname of a farmer who began cultivating the variety in this region in the early 20th century, helping to preserve and spread its use across the area.
From a viticultural perspective, the Impigno vine is characterized by good vigor, medium ripening, and generous yields, making it a reliable choice for blending in regional white wines. The grape produces medium-sized, green-amber berries with thin, soft, and slightly waxy skins. The bunches are medium in size, sometimes winged but generally loose, allowing for good air circulation. The leaves are medium, simple in shape, and typical of Apulian native varieties.
Wines made from Impigno are typically straw yellow in color, with a fresh, fruity bouquet and a dry, well-balanced palate. Although rarely bottled as a single-varietal wine, Impigno is valued for its ability to enhance blends with other local grapes such as Verdeca, Bianco di Alessano, and Francavilla, contributing freshness, aromatic lift, and structure.
