Ronco dei Tassi

The name ronco is Friulian for “hillside, terraced vineyard”. Ronco dei Tassi, true enough, is a little nook of paradise in the heart of Collio, bordering the splendid National Park of Plessiva; one of those rare locations where you feel nature and man are in perfect harmony. Founded in 1989, the property was named after the numerous badgers (tassi) at home in this untouched natural scenery. Founder, owner and winemaker is Fabio Coser. Initially a consultant oenologist, his earlier career allowed him privileged knowledge of the area’s terroir and styles, so that by the time he chose a winery of his own, he already knew Collio like the back of his hand – and belonged here as surely as most of Italy’s finest whites. Over the intervening years, the estate’s total surface has increased to 59 acres (24 hectares), 33 of which (13.5 ha.) under cappuccina and Guyot-trained vines, planted on calcareous marls and laboriously terraced at 140 to 250 meters (460 to 820 feet) above sea level. Substantial investments have been poured into creating a new, state-of-the-art underground winery and barrique cellar, comprising 300 new barriques of French and American oak; vineyards have been purchased or replanted with a density around 2,500 vines per acre, yielding 1-1.2 kilos of grapes per stock and an average total production of 73,000 bottles yearly. Oak is carefully modulated to maintain varietal character and goût de terroir: the wines sojourn briefly in barrique without their unique fruit, fragrance and finesse being either stifled or distorted by wood. Annual production is principally subdivided into 27,000 bottles of Pinot Grigio, 13,500 altogether of Tocai Friulano, Sauvignon and Collio Bianco, and 5,500 of Collio Rosso. Fabio is flanked by wife Daniela and sons Matteo and Enrico.
