Maison Champy is the oldest wine company in Burgundy boasting a history dating back to 1720. The winery, which has been declared a historic monument by UNESCO, was designed by the famed architect, Gustave Eiffel and sits above an ancient 15th-century Jacobian monk cellar, where the wines are aged in the heart of Beaune. It was at Maison Champy where renowned scientist, Louis Pasteur set up a laboratory and developed the pasteurization method. When Pasteur published his findings, he gave special thanks to fourth-generation Beaune wine merchant, Claude Champy. Pasteur?s laboratory equipment can still be seen today when visiting the Maison.?
