The red grape variety (also VB 91-26-5) is an interspecific new breeding between Cabernet Sauvignon x unknown resistance partners. It contains genes from Vitis amurensis and Vitis vinifera. The hybrid was crossed in 1991 by the vineyard owner Valentin Blattner in Soyhières in the canton of Jura in Switzerland. The early ripening vine is susceptible to powdery mildew but resistant to frost. It produces fruity red wines. The variety is grown exclusively in the Netherlands by the producer Colonjes (after whom it is named) and in Sweden. However, no stocks were reported in 2016 (Kym Anderson statistics).
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".Prof. Dr. Walter Kutscher
