The Colli di Conegliano designatin, without further qualification, according to the specifications is reserved to the white wine that comes from a blend composed of Manzoni Bianco (min 30%), Pinot Bianco and/or Chardonnay (min 30%), Sauvignon and/or Riesling Renano (max 10%). Colli di Conegliano Rosso comes from a blend of Cabernet Sauvignon, Merlot, Cabernet Franc, Marzemino, for not less than 10%, Merlot in any case can not exceed 40%. Torchiato di Fregona is produced with Verdiso grapes (min 30%), Prosecco grapes (min 30%), Boschera grapes (min 25%). The Boschera vine is cultivated only in the area of Fregona, cold–resistant, and its production is scarce. Clusters are sparse and slightly reddened.
The area of production of the Colli di Conegliano D.O.C. wines includes entirely or in part the territory of twenty Municipalities in the high hills of the Treviso area: Conegliano, Susegana, Pieve di Soligo, Farra di Soligo, Refrontolo, san Pietro di Feletto, Miane, Follina, Cison di Valmarino, Revine Lago, Tarzo, Vittorio Veneto, Fregona, Sarmede, Cappella Maggiore, Cordignano, Colle Umberto, San Fior, San Vendemiano, Vidor.
This area has always been a place of research and production of important wines: the reference, here, is to those wines which, although different, were equalized with the Ministerial Decree of 3rd August 1993, under the same Colli di Conegliano Designation of Controlled Origin: Bianco, Rosso, Refrontolo Passito, Torchiato di Fregona. For all wines produced with this designation, care starts the vineyard: the choice of the most favorable terrain, with high density of planting, unexpanded breeding forms of vineyards, modest yields of grapes per vine.
