My kombucha is not bubbly?

How do I increase the carbonation of my kombucha tea? One of the reasons your kombucha may not be bubbly is because it’s fermented for too long.The good yeasts in kombucha eat the sugar and then release carbon dioxide. This is what creates carbonation. If you let it ferment too long, the kombucha goes flat. If you don’t let it get vinegary, it will stay bubbly. When the yeasts eat the sugars out of the tea, they make carbonation. When they run out of sugar to eat, they start to die and so do the bubbles. Second-fermenting is another way to achieve carbonation. The process requires adding juices or extra sugars and then capping off bottles and letting them ferment so the yeast can transform the sugars into natural carbonation.
