On the first day of our multi-day offline with tsunami (The Tsunamithon ) we drank a Gould Campbell out of the cellar of the Roots'.
When I wanted to decant the bottle, I saw that the cork had been partly turned into dust. The upper centimeter was gone. There were also strange marks on the cork. StevieCage suggested that it could have been some sort of beetle (or larvae) that ate its way into the cork. For his explanation and wodka-soaked determination, take a look at this thread.
I had heard that this could happen, but had never actually seen it before. Has anyone of you ever experienced this in a bottle?
And, not really unimportant, do these beetles have the bad habit of spreading to other bottles? If so, I have some checking to do.
