Malvasia Collio DOC

Ronco dei Tassi is a family-owned and run estate, founded in 1989 when Fabio Coser and his wife Daniela bought their first 9 hectares (22 acres) in Collio Goriziano, in the township of Cormons in Friuli. The estate now extends 30 hectares (75 acres) of which 18 (45 acres) are under vine, all located in a beautiful natural park, which is protected by the region of Friuli. Ronco dei Tassi takes its name from the way the vineyard are set up: ronchi in Italian means terracing. They are set up this way so the vines get the most sun possible. While tassi, means badger in Italian, which reminds us of the small groups of badgers that visit the property during harvest to sample the ripe and juicy grapes.

The winemaking team believes that great wines are made in the vineyard and they thus spend a lot of time up close and personal with the vines with the aim of cultivating perfect and healthy grapes to be transformed, using the least invasive and most natural ways possible, preserving the innate characteristics of the grapes, the terroir and of course, the vintage.

100% Malvasia Istriana from the Quarin vineyard, whose soil has Eocene origins. The vineyard is very small, just 1.5 hectares (3.7 acres) and is 60 years old. The variety is extremely deep-rooted, documented in the Istria area in the 1300s, but grown even in ancient Greece. Ample fruity aromas on an intense and layered nose; well balanced on the palate, silky in texture yet sustained by zesty acidity and excellent structure.
