Background
The Valais controlled designation of origin (AOC) guarantees the geographical origin of Valais wines. In October 2026, the Canton of Valais tripled its checks, according to Le Nouvelliste. The cantonal chemist then told the daily that other frauds remained to be uncovered. These remarks drew reactions from the wine industry.
The key points
Questioned in the Valais Grand Council on 13 November 2026, the Council of State backed the cantonal chemist. State Councillor Mathias Reynard spoke of “worrying results” from the analyses.
According to these analyses, a significant share of the AOC wines checked show an isotopic value that is atypical for Valais. This value deviates from the references expected for their geographical origin. The wine industry, for its part, denounces the “discredit” cast on Valais wines.
