Rondo is a blue PIWI (pilzwiderstandsfähig) variety with great vigour used for red and rose wine. It was created in 1964 by Professor V. Kraus in what was then Czechoslovakia by crossing the varieties Saperavi Severnyi (a Russsian variety) and St. Laurent, and is further processed by the German Wine Research Institute in Geisenheim. Rondo is a grape variety that ripens early and is very resistant to winter frost and diseases. The grapes give a full-bodied ruby red, harmonious  wine with a concentrated taste. It is also used in cuveés (blend of different grape varieties), for example with Regent and Solaris.
