Voltis

Voltis is the first fungus-resistant (PIWI) variety authorised in the Champagne AOC, admitted in 2021 on a trial basis. It is a complex hybrid that resists downy and powdery mildew, dramatically reducing the need for copper- and sulphur-based vineyard treatments — a direct response to the AOC's sustainability targets.

Producers are allowed to plant Voltis up to five percent of a holding, and to include up to ten percent of it in a blend. Stylistically it is too early to generalise; early trials suggest a clean, citrus-driven profile without the depth of the historic varieties. The point of Voltis is not flavour but adaptation: a working tool for a climate the AOC didn't evolve under.
