I know that's a very-very-very-very old thread, but I had to help anyone!
After visiting Asian country, America, Australia, I wanted to find this healthy drink in Swiss as weel.
I was looking everywhere and I finally found it in Coop City Lausanne (Rue Saint-Laurent 24-30). YESSSSSSS,THE TREASURE IS MINE! Even for 5 CHF 5 bottles, worth it.
I'm still looking everywhere I go, to found another sealer, in case of Coop stop to sell it
