The Estate The land extends over 20 hectares of which 12 are under vine and the remainder woodland. Located in Collio Goriziano, in the village of Cormòns, at an altitude ranging from 140 to 200 metres above sea level and to the furthest extent of the nature reserve at Plessiva, this is a protected environment.
Rich in naturally occuring flora (oak, robinia, chestnut, birch, hornbeam) and wild animals (boar, roe deer, wolves, badgers) that live undisturbed in this idea habitat, this is one of the most tranquil spots of the Goriziano hillside.
The name of the estate is derived from the predilection of local badger colonies to guzzle the sweetest bunches of grapes as they ripen; they particularly favour vines situated in exposed terraces, known as “ronchi”, hence Ronco dei Tassi.
White grape varieties cultivated here are Pinot Grigio, Pinot Bianco, Tocai Friulano, Sauvignon and Malvasia; red varieties are Merlot, Cabernet Sauvignon and Cabernet Fanc. These varieties are employed to yield five styles of wine: Pinot Grigio, Sauvignon and Tocai Friulano from the grapes of the same name; "Fosarin" Collio Bianco from a blend of Tocai Friulano, Malvasia and Pinot Bianco; and "Cjarandon" Collio Rosso from Merlot, Cabernet Sauvignon and Cabernet Franc. The latter two, whilst produced from more than one grape variety, can be termed DOC "COLLIO".
The philosophy of the winery, apart from maintaining rigorous control over the growing phase as well as all qualitative and quantitative aspects, revolves around traditional cellar practice, avoiding as far as possible all additives or improvers in order to retain both the true character of the fruit, and the specific characteristics of the land in the finished product.
The Vines Ronco dei Tassi is located in the heart of Collio, a DOC zone that extends from the northern, hilly zone of the province of Gorizia to the border with Slovinia. The winery and its vines occupy the highest plateaux of the hilly zone, made up of slopes running from east to west, exposed to the midday sun – conditions sought after as ideal for vine cultivation throughout history. The vines also benefit from a kind of shield formed by the foothills of the Julian Alps, protecting them from the northerly winds. Meanwhile, the closeness of the sea modifies the climate, protecting the vines from extremes of temperature.

The Collio soil is made up of marl and stratified sandstone dating back to the Eocene period, which can easily be made out in the walls of the barrique cellar at Ronco dei Tassi.. The rocky formations crumble readily under usual atmospheric conditions, creating a kind of compost which forms an ideal substrate for viticulture.
The Wine cellar The cellar, located below the business centre, is made up of a large warehouse, a room for stainless steel fermentation, and a further room for maturation in barriques, excavated precisely 12 metres underground, in the heart of the Montona hill.
Here both red and white wines rest in French oak barrels at a temperature between 12° and 14° and a humidity that remains constant throughout summer and winter.
