Thank you very much Walter for this information! The bottle is claimed to be more than 100 years old. It came from a 80+ year old lady and she got it from her father who supposingly also had it a very long time. But I think in one of your other posts you said that the spring cap was invented in late 1920's, so it can't be that old.
Would this be drinkable? I would probably drink it but unfortunatly the bottle is owned by my mother who wants to sell it. Maybe I will buy it myself depending on what it is worth. I'm also very curious if Jojo will come up with more information!
