Thanks for sharing! I was there a few years back. What I noticed was that a lot of the smaller vineyard owners were telling the same story. It was that a few big brands (I believe Moet Chandon was the main one) are buying up more and more small vineyards. As a result (since the amount of land for Champagne is capped), more and more small Vineyards are disappearing and with them their wines. Don't know how bad it really is, but I found it kind of sad to hear.
