The development of trade between China and Europe also contributed to the appearance on the continent not only of tea but also of the tea mushroom.

The fermented tea drink was more easily adopted n the eastern part of Europe, where the tradition of consuming fermented foods had existed for a long time (sauerkraut, pickles, bread acid). In view of this fact, kombucha spread easily among Slavic peoples. In particular, it has been popular for many generations in Russia.
