Gas storage tanks and their importance

Someone has a cellar full of preserves, another has a cellar full of wine. Štěpán Vican, a sales dispatcher from MND Energy Storage, grows mushrooms in his cellar. Specifically SCOBY, which he then uses to make special tea drinks or kombucha in combination with herbs. He calls them Herbucha and now he is opening an e-shop: kombuchazmoravy.cz. He wants to show people that kombucha can be very tasty, because most people are fixated that it's healthy, but not always good.
