Rive di Collalto Prosecco Valdobbiadene DOCG Extra Brut – 2021

Region: Italy - Veneto


The Collaltos carry on a family legacy as owners and tenants of 3200 acres of land north of Venice given to their family over one thousand years ago. The signs of history, culture and nature co-exist with farming practices that fully respect what is a centuries-long tradition passed down by the Collalto family. 160 acres of farmland are given over to vineyards for the production of Borgoluce wines and sparkling wines. The Valdobbiadene D.O.C.G. region is home to the vineyards of Borgoluce’s finest Prosecco.

Winemaker's Notes

From the “Rive” (very steep hillsides) of the Collalto hills, an extreme brut that allows full expression of the fruit. Dry and harmonious on the palate. A broad bouquet with hints of white flowers, lily of the valley and green apple.

#73 of Enthusiast 100: The Best Wines of 2023


Grown high in the hills of Valdobbiadene on very chalky soils, this wine proves that not all Prosecco are the same. Lifted aromas of fresh green apples, lemon zest, crushed chalk and heady white-flower aromas. Cool and crisp on the palate, with a rush of mixed orchard fruits and blanched almonds finishing with persistent minerality and fresh acidity.
