Origin: The PIWI variety Fidelio was bred in 1981 by Prof. Dr. H. Becker at the Institute for Grapevine Breeding in Geisenheim. 

Interbreeding: Ehrenbreitsteiner X Fr 52-64

Characteristics: The grape variety has an early to medium bud burst and flowering time and convinces with a strong, upright growth. The winter frost resistance is good. Fidelio has a medium to late ripening time. Yield, must weight and acidity are high. Two treatments against mildew are necessary, depending on the weather. 

Grape: This fungus-resistant grape variety has a loose cluster structure, which makes it less susceptible to botrytis. The grape is large, shouldered with large, round, green to slightly yellowish berries.

Wine: The wines from Fidelio are delicately fruity and fragrant with Riesling-like acidity. The bouquet is reminiscent of rose with hints of quince and citrus.

Cultivation: The variety has medium site requirements.
