For the 175th anniversary of the company, the public was invited to visit Kessler House for the first time. In a short time, the wine cellar tours evolved into a tourist attraction for visitors from near and far. At the same time, a Saturday rendezvous was inaugurated and held in the reception rooms of Kessler House. This event was locally known as ‘Sekt in the City’ and enjoyed cult status for years to come in both in and around Esslingen.
