The first vines of the white Piwi variety Voltis were planted in Champagne. Voltis, which is resistant to powdery and downy mildew, was approved by the Champagne PDO and the Institute of Origin and Quality (INAO) at the end of 2022. This makes it the first Piwi variety ever to be accepted into a French appellation. In 2033, a decision will be made on its final inclusion in the Champagne catalogue of varieties.
The Comité Champagne, an inter-branch organisation, will set up technical and oenological monitoring. For this, the winegrowers will provide the Comité with grapes and must from their Voltis plots and neighbouring plots.
In Champagne, 5 ha are expected to be planted with Voltis this year. The grape variety is currently not allowed to make up more than five percent of the vineyard area of a winery and no more than ten percent of a blend, in order not to influence the organoleptic profile of a champagne too much. For this, the grapes must be vinified separately. According to initial statements by the winemaker involved, Alexandre Rat, Voltis is "apparently about two weeks later than the other grape varieties".
