The white grape variety (also Geilweilerhof GA-49-22) is a new variety between Bacchus x Seyve-Villard 12-375(Villard Blanc). With the same parents the two new varieties Sirius and Staufer were created. The name comes from the well-known bird from mythology, which burned itself to rise from the ashes new and rejuvenated. It contains genes from Vitis berlandieri, Vitis rupestris and Vitis vinifera. The hybrid was crossed by the breeder Dr. Gerhardt Alleweldt (1927-2005) at Geilweilerhof in Siebeldingen-Pfalz. The plant variety protection was granted in 1992. The medium-early ripening, frost hardy variety is resistant to both types of mildew and is therefore considered a so-called PIWI variety, but is susceptible to botrytis. It produces yellow-green white wines with moderate acidity, discreet muscatel and aromas of elderberry. The variety is also used as a table grape. In 2009, it occupied 48 hectares of vineyards in Germany (mostly in the Nahe and Rheinhessen regions). There are further stocks in England, Denmark, Sweden, Switzerland and Austria.
