Thomery circuit
Guided tour of Thomery centered on the Chasselas
A journey through the centuries to discover the varied cultures of the “Chasselas.” It would later surge in popularity thanks to a preservation technique called “à rafle verte,” which makes fresh grapes available year-round. The canes and bunches were stored from October to May in small glass bottles filled with water and a piece of charcoal, in grape-storage rooms, protected from heat and light. A unique specimen of this setup will be revealed during the tour.
Participation requirements: Limited spots - Free | Booking required - 0160704166, tourisme@ccmsl.com
