Visited Pommery champagne house in August 2018. It should be pre-booked in advance through the official web site. The guide told fascinating story of the house, Madam Pommery and champagne making process. One of the cellar rooms contains the most prominent bottles, including a bottle of the first original brut created in 1874 (only one of two perfect vintage years, when no additional sugar is needed). There is also artwork inside the cellars – large sculptures completed in 1884 by Gustave Navlet.  Currently the cellars a part of large Vranken Pommery Monopole Group with sales of 300 million euro and 800 employees. Champagne testing followed the tour and it is amazing. In overall, good experience and interesting truly unique region.
