I also want to hear that this is not true… Your video reminded me about one experience from my past. Once I had Kombusha and I was drinking it and changed water every day maybe for a month or so. After I was lazy to change water and I left it in the cupboard for some time. I actually red that strong Kombusha is good for hair or something else (I dont remember already). When I took Kombusha out it was full of small worms, so small that I did not notice them at once.
I am thinking every day from where these Rope worms are coming. I suspect they have some relation to jelly fish. And Kombusha look very much like jelly fish… What surprise me that worms could live in this highly concentrated Kombusha, so probably in vinegar they also can.
So my question would be if people suffering from Roap worms ever remember drinking Kombusha?
