The yellow Ribolla grape is an ancient grape variety of the Friuli-Venezia Giulia, cultivated since Roman times in its area of excellence, the hills of Rosazzo. In the twelfth century it was already known and appreciated among the regional wines "Rabiola" Collio. Some authors assume that the vine is a derivation of the grape "Avola" imported by the Romans during their occupation of these lands, but there is no historical documentation that may support this theory. In Slovenia and Croatia it is called Rebula, and it is believed that its origin was in its southern islands of Dalmatia, or further south to Kefalonia; some believe to have been imported in Friuli by Venetian merchants in more recent times, around 1100. Its area of excellence is still the hills between Udine and Gorizia, and in denominations DOC Isonzo, Collio and Friuli and eastern hills in Rosazzo DOCG. Excellent results also gives Rebula the Slovenian Collio. The yellow Ribolla grape has never spread in plain, preferring dry and hilly soils where it gives rise to intense and structured wines. From Ribolla grapes vinified in white is produced a wine with a fresh acidity always lively, delicate flavor and the characteristic fruity aroma. In some areas of the Collio of Gorizia as "Ribolla" is still indicated the grape must Ribolla near the end of the phase of fermentation. In this phase, which usually falls in the first days of the month of November, it is in the presence of a wine not yet fully formed in which a part of the sugar has not yet been converted into alcohol and in the wine are still present, in suspension, a part of the natural yeasts. It is an "embryo" of wine, often still moved, where the aromas of the fresh fruit, the sugar residue and the lively acidity blend creating a unique and inimitable sensations of smell and taste. The Ribolla wine is a still wine with a characteristic pale yellow, sometimes with greenish hues. The scent is delightfully floral and fruity, very elegant, and sometimes reminiscent of green apple, peach and lemon. The taste is thin, lively, cool and dry, while the aftertaste is slightly aromatic.
