Found this earlier in the week...the shop manager only had a handful. Doesn't seem to be much info about it anywhere that I can find. We enjoyed one of the 2 bottles we managed to acquire.
Great Swiss beer! IMHO, the "Trois Dames" is the best Swiss brewery with BFM (Brasserie des Franches-Montagnes). BTW, this is a special edition that I've never seen around here. You damn Americans consume everything!
