Kombucha is a fermented, enzyme and probiotic-rich tea, which you either can make yourself or buy pre-made in health food stores. You can drink it as it is, add to smoothies or even make into ice lollies. We love the festive bubbles you find naturally in kombucha. They are perfect in a fruity, alcohol-free summer cocktail. If you do not start a new batch right away, you need to rinse out the mushroom jars every 4 weeks. Just put the mushroom and culture into a bowl while rinsing the jars with hot water, and then pour them back into their jars. Store at room temperature.
