I am also RY4 fan. The best RY4 I have found is the Polish Mollinberry RY4 it is so close to the origional RY 4 available years ago from China that it bought tears to my eyes when I tried it. I am fortunate that in my country Australia, there are two vendors that sell it. As to if they will post overseas I do not know as postage charges are exorbitant. Here is where you can buy it direct from Poland. Molinberry Flavours Hope this helps you in your search.
Sounds delish, Acer! Sadly, they don't ship to the US. Also, they don't list the mg. strengths?
surprising, was looking around and darn if I didn't find each of the flavors...
about 8-9ml of each so I dumped them all into the pie-stash-io bottle and will let them brew for awhile
and see what becomes of it -- a great smell so far , seems inviting...
