I ACCIDENTALLY FERMENTED MY KOMBUCHA FOR TOO LONG AND NOW IT'S VERY SOUR.
Unfortunately, it sounds like your batch has turned into kombucha vinegar. The good news is that kombucha vinegar makes really great (and potent) starter liquid for your next batch. So keep a cup or two to brew your next batch with. You can also use it as a great base for salad dressings, household cleaners, and even hair tonic! It might not be tasty to drink, but if you Google around you’ll find plenty of other cool uses for it.
WHAT TYPE OF WATER CAN I USE FOR MY KOMBUCHA BREW?
We recommend using filtered water, spring water, or purified water from reverse osmosis. You can use water from the tap if you run it through a Brita type filter, or if you have a built-in filter in your fridge that works too!
WHEN DO I KNOW IF MY KOMBUCHA IS READY?
You know when it is ready because it will be to your liking. I will usually test my kombucha after 4-5 days and keep testing it every 1-2 days after that until it's to my liking ?
