Rive di Collalto Prosecco Valdobbiadene DOCG Extra Brut – 2020

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

This wine illustrates the unique character of a hill. 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.

Sweet peach, white flowers, smoke and hints of vanilla bean waft up from the delicate yet remarkably pretty 2020 Extra Brut Prosecco Superiore Rive di Collalto. This is savory and angular in feel, with saline-tinged bubbles ushering in tart pit fruits; yet energy is nicely maintained through bright acidity. It leaves hints of green melon under an air of brown sugar, which I find wildly attractive, while tapering off long and wickedly fresh. (Lot# 20 L21M07) 2021 – 2025
