Storage & Shelf Life: How long does kombucha last?
The shelf life of kombucha depends on factors like storage conditions, packaging, and whether it’s opened or unopened. Proper refrigeration or storage can help extend freshness, while freezing can be an option for longer preservation. Knowing the typical expiration timeline and signs of spoilage can help prevent waste and ensure food safety. Learn the best storage methods and how to tell if kombucha has gone bad.
How long does kombucha last?
🧊 Fridge Life
7–10 days (after opening), 3–6 months (unopened, refrigerated)
❄️ Freezer Life
Not recommended (freezing kills live cultures)
☀️ Room Temp Life
3–5 days (may continue fermenting and become too carbonated)
What’s the best way to store kombucha?
Unopened kombucha can be stored in the fridge for months but will continue fermenting at room temperature. Opened kombucha should be tightly sealed and kept cold to maintain carbonation. Avoid freezing as it kills probiotics and alters flavor.
How can you tell if kombucha has gone bad?
Overly sour or vinegary smell, loss of carbonation, mold on the surface, or off-putting taste.
What’s the best container for storing kombucha?
Glass bottles with airtight lids for maintaining carbonation.
How can you tell when kombucha has expired?
Homemade kombucha ferments faster than store-bought, so it may spoil sooner if not refrigerated.
