The small wine-growing community lies near Lake Neuchâtel in the Bonvillars area in the north of the Swiss canton of Vaud. It was first mentioned in a document in 885. The vineyards have Grand Cru status and comprise 28 hectares of vines, most of which are planted with Chasselas and some red varieties. The municipality became famous mainly because of the legal dispute with the French Champagne region. After years of legal disputes, the municipality was banned from using the designation of origin "Vin de Champagne", which is reserved for France, from the 2003 vintage onwards on the basis of the bilateral treaties between Switzerland and the EU. Finally, in 2021, a court ruling also prohibited the municipality from using the name Champagne on its label. The legal disputes do not only concern wine, but also other products. In 2008, the Cornu bakery, which is based in the commune, registered its Flûtes brand "De Champagne Suisse" (Flûtes = salt and cheese aperitif biscuits) in Bern.
