It would be neat to visit Arbois and catch this sometime. The NY Times has me thinking it's the wine geek's response to mardi gras.
Little cups dangling from neck chains?
Jura, France -- where La Percée du Vin Jaune takes place -- is a wee (1800 hectare) place of clay and limestone that produces three grapes unheard-of anywhere else: Savagnin, Poulsard and Trousseau.
More importantly (at least for the tourism department), Jura is the home of yellow wine. Yellow wine is aged in oak for six years and three months. It keeps 50 to 100 years, says Wikipedia, and the NY Times goes on to describe it as a love/hate kind of drink upon first sip.
