"Ruggeri - hands down, this is one of the top five Prosecco producers", Decanter, July 2013
The Ruggeri winery was established in 1950 by Giustino Bisol, whose family boasts a deeply rooted, centuries-old tradition in viticulture in the Valdobbiadene area. The winery was established in Santo Stefano di Valdobbiadene to produce and promote the sparkling Prosecco Superiore and Cartizze wines. It was originally housed in small premises in the village of Santo Stefano di Valdobbiadene. After a temporary move to a larger site in the centre of the village, in the early Nineties it was relocated to new, larger and more rational premises which can receive and process almost 3,000 tons of grapes which are brought there every harvest. Today the winery is run by Paolo Bisol, who is assisted by his children Giustino and Isabella.
The Prosecco Superiore DOCG grapes are usually delivered by over a hundred vine-growers. Nearly all of them have their vineyards in the municipality of Valdobbiadene, while 25 also grow Cartizze grapes. It should be noted that many of the superior vineyards lie in the historic districts of San Pietro di Barbozza. Santo Stefano and Saccol, which have always been renowned for producing the best in terms of quality. Ruggeri owns a small vineyard of Cartizze and 20 hectares on the nearby Montello, 12 of them are cultivated with Pinot Grigio and Glera (traditionally called Prosecco). About 1 hectare is dedicated to the growing of Recantina, an ancient and authochtonous red grape variety which was recovered thanks to the hard work of cooperation with the Istituto Sperimentale Per la Viticoltura di Conegliano (School of Viticulture of Conegliano).
