The red grape variety (Irac 291) is an interspecific new variety between Gamaret x Bronner. It was named after the Swiss national hero Divico (130-58 BC), who, as leader of the Helvetian tribe of the Tigurines against the Romans, won the battle of Agen in 107 BC and negotiated with Julius Caesar (100-44 BC) in old age. It contains genes from Vitis amurensis, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1997 in Switzerland at the Institute in Changins by grower Jean-Laurent Spring. The same parents also produced the white variety Divona.
