In the category of what I learned on my European vacation, I want to introduce the collection of those metal caps that sit on the top of a champagne cork underneath the wire. Who knew these were collectables? They are apparently traded with great fervor in Champagne country. Many of these plaques de muselet are much more colorful and artistic than the one I pulled off my New Year's Eve bottle of Champagne last night. But I've gotta start somewhere.
