Terrano is an indigenous grape variety from Friuli-Venezia Giulia, belonging to the Refosco family. Its traditional habitat is found in the iron-rich soils of the Carso (Karst), and for this reason, during the Austro-Hungarian era, the wines produced from Terrano were praised for their medicinal properties, particularly noted for treating anemia. The origin of the name is likely linked to the organoleptic characteristics of the wine, which is known for its strong flavor and intense color. “Teer” in German means tar, emphasizing its robust nature. In Slovenia, Teran refers to the wine, not the grape, which is called Refošk. In Italy, it is also known as Refosco Terrano. Terrano produces the most expressive red wine of the Carso, embodying the rugged terrain and unique climatic and geological features of this region.
Terrano is relatively unknown outside of Friuli-Venezia Giulia, where it is overshadowed by the more famous Schioppettino and regional Merlots. However, its wines have significant potential due to the excellent enological qualities of the grape. Terrano has large clusters, reaching up to 20 centimeters in length, with a pyramidal shape, wings, and moderate compactness. The berries are medium-sized, slightly oval, with thin, blue skins covered in abundant pruina. The resulting must is slightly acidic. Terrano is a moderately vigorous vine, with consistent and abundant yields. Harvest occurs at the end of September, and it thrives with expanded training systems and long pruning. It has excellent resistance to humidity and rot.
Terrano is considered the symbol of viticulture in the Carso and is commonly found in inns and taverns in the province of Trieste. Terrano wines are characterized by marked acidity and tannins, making them ideal companions for charcuterie, cheeses, or cevapcici, a traditional dish of spiced minced pork. The Carso Terrano DOC is produced by vinifying Terrano with small percentages of Pinot Nero. In Emilia-Romagna, Terrano is known as Cagnina, cultivated in the provinces of Forlì-Cesena and Ravenna, where it is part of the DOC Romagna.
