This museum/presentation was the best exhibition we saw of either wine or castles in three weeks of touring Burgundy and the Loire. The lit map showing the geography of the various domaines is brillliant - the colors change depending on the history, soil type, sun time, and so on of the plots - all explained in excellent English. Then there are short videos (subtitled in English) explaining the cultivation, harvests, and vinification by the vintners themselves, a charming and passionate lot. I particularly liked one old guy in his 80s who'd been making wine all his life yet was open to new methods. There are displays of everything from soil, root systems, and bugs for those wishing to be immersed in the process.
At the end, there is a tasting of one Sancerre wine, a good one - and you keep the glass - but a comparison of two or more would have demonstrated the complexity of the region. The garden patio where you can savor that one glass looks out over the beautiful land. The main thing I absorbed from this visit was the all-consuming joy and dedication of the vintners.
