The white grape variety (also FR 493-87) is a new variety between Solaris x Gelber Muskateller. It contains genes from Vitis amurensis, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1987 by Norbert Becker (1937-2012) at the Freiburg Viticultural Institute (Baden-Württemberg).
The early-maturing, high-yielding and frost-hardy vine is resistant to both types of mildew (high) and botrytis and is therefore considered a PIWI variety. It produces acidic white wines with an intense muscat flavour.

I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
