The white grape variety (also known as Freiburg 993-60) is a new variety between Seyve-Villard 5276 (Seyval Blanc) x (Riesling x Pinot Gris). It contains genes from Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1960 by Dr Johannes Zimmermann (1907-1998) at the State Viticultural Institute in Freiburg. The name is derived from the Merzhausen district of Freiburg, where the institute has several experimental vineyards.
It was a crossing partner of the new varieties Baron, Bronner, Cabernet Cantor, Cabernet Carbon, Cabernet Carol, Cabernet Cortis, Calastra, Helios, Monarch, Pamina, Prior, Rinot, Solaris and Termantis.
