Ruggeri is one of the most prominent Italian wine firms and its Prosecco di Valdobbiadene sparkling wines are among the most complete expressions of the style. 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 place-name “Case Bisoi” (that is “the Houses of the Bisols”) is to be found on the oldest maps of the area, in the heart of the zone now known as Cartizze and once called “Chartice” or “Gardizze”. Here, the Bisol family has been cultivating vines since 1542. In 1993 the winery was relocated to new, large and ergonomically-designed premises.
