The Piwi grape variety "Felicia" has been approved for quality viticulture at the beginning of 2021. This was announced by the Julius Kühn Institute in Quedlinburg. The fungus-resistant white wine variety was bred by the Institute for Vine Breeding at the Geilweilerhof and was granted variety protection as early as in 2004. "Felicia" was created in 1984 from a crossing of the Sirius and Vidal Blanc varieties. According to the Julius Kühn Institute, its cultivation would save about two thirds of the fungicides that would otherwise be necessary. It is moderately resistant to powdery and downy mildew and also has resistance to black rot. This also means that less copper is needed in cultivation. The institute describes the aromas as a combination of ripe fruit aromas of apple, apricot and banana, occasionally combined with a muscat tone.
