Once you open that bottle, the clock starts ticking, but it’s a very generous clock. Most kombucha stays pleasantly fizzy and tasty for 5 to 10 days in the fridge. After that, it’s not a villain—it’s just evolving, like a fine sourdough starter.
Here’s the secret: kombucha is a living drink, full of active cultures and a bit of yeast. That’s what makes it so fun—it’s basically a science experiment you can drink. The flavor will slowly shift from sweet-tart to more vinegary and funky, which some people actually crave.
Your Senses Are Your Best Tool
Forget expiration dates; your nose and tongue are way smarter. If it smells like a pleasant, zesty salad dressing, you’re good. If it smells like a forgotten science project in high school, trust your gut (pun intended) and toss it.
A little sediment at the bottom? That’s just the SCOBY’s babies—totally normal, and actually a sign of a healthy brew. Give it a gentle swirl and enjoy the extra tang.
