This is one of the most fascinating rescue stories in Italian viticulture. In the 1920s, a man named Antonio Longanesi discovered a single, unknown vine climbing the branches of an old oak tree in the swamplands of Emilia-Romagna. He propagated it, saving the grape from total extinction. Today, that grape is known as Uva Longanesi, and the wine made from it is trademarked as Bursôn—the historical nickname of the Longanesi family. Tenuta Randi is one of the key pillars of the Consorzio Il Bagnacavallo, a small, fiercely dedicated group of Romagnolo producers protecting this ultra-rare variety. Grown in the alluvial plains of Ravenna, where the Adriatic Sea influences the climate, the Longanesi grape is notoriously thick-skinned and rustic, demanding immense patience both in the vineyard and the cellar. To tame its massive structure, the "Selezione" tier often borrows techniques from Amarone, utilizing a partial drying of the grapes (appassimento) and extended aging in oak. It is dark, brooding, and powerfully structured.
