A hybrid of Diana and Chambourcin created in 1967 at the Geilweilerhof Research Centre (D), it was named in reference to the famous "Regent" diamond (140.5 carats) found in India. This inter-specific variety is very early and highly resistant to cold and fungal disease, suited to the northern regions. In Switzerland, it is particularly found in the cantons of Zurich and Schaffhouse where it produces generous wines with silky tannins.
