I can only review a purchasing and gift giving experience from England to Berlin. It was easy to purchase (as google translated the website, as I don’t read German). I knew what I was looking for as my son had recently spoken about discovering fermented tea. He said it was packaged well and he was probably going to age it for a couple more years but that he’d have one taste before he did. He was pleased. Usually I don’t end up getting actual gift cos purchasing in German is tricky. I felt it was expensive but not in excess for the item. An expensive appreciated gift from an expensive part of the city he doesn’t usually afford to shop in.
