Kombucha is a fermented sweet tea that can be flavored with fruit. It tends to have a fizzy taste with a bite.
Kombucha is made by adding sweet tea to a scoby (symbiotic culture of bacteria and yeast) and allowing it to ferment for a certain amount of time. After removing the scoby, depending on your preference, you can add fresh or frozen fruit or fruit juice. Allowing it to ferment for a few days will help the flavors to meld and help it build "fizz".
Kombucha is said to help detox the liver and aid in digestion. It also contains glucosamine, so it can help with your joints. And it is very high in anti-oxidants, so it will boost your immune system. It hast lots of probiotics and amino acids, and is thought to help prevent and even treat cancer.
Always brush your teeth after drinking Kombucha, just to make sure you protect the enamel on your teeth.
