In 1390, the Italian writer Francesco di Manzano noted that wine made from Refosco dal Peduncolo Rosso was the favorite of Augustus's wife Livia. Beginning in the 1980s, the grape experienced a revival in interest along with other Friuli-Venezia Giulia grapes, and more wines made from the grape were exported internationally.

Viticulture and winemaking
In Friuli, Refosco dal Peduncolo Rosso vines are planted in both hillside and level terrain. Ripening is a concern and the grape requires sufficient access to warmth and sunlight, which play a major role in deciding where to plant the grape. Despite being a slow ripener, the grape does have good resistance to rot that can develop during autumn rains. The deeply colored wine produced from the grape tends to be full-bodied with high acidity levels and flavors of plum & almond notes. Since the renewed interest in the grape of the 1980s, winemakers have experimented with producing more internationally recognizable styles of the grape with techniques like malolactic fermentation and new oak aging to mix results.
