Refrigerator: 7-10 days

Freezer: Not recommended

Overview

Kombucha (store-bought, opened) lasts 7-10 days in the fridge. Complete shelf life, storage tips, and spoilage signs.

Key Details

  • Refrigerator: 7-10 days
  • Freezer: Not recommended
  • Pantry/Counter: 1-3 months (unopened, pasteurized)
  • Category: Condiments

Why This Matters

  • Spoilage sign: Extremely vinegary taste beyond normal tang
  • Spoilage sign: Mold on surface (fuzzy, not the SCOBY)
  • Spoilage sign: Off or chemical smell
  • Spoilage sign: Excessive fizziness or bottle bloating

How To

  1. 1Keep refrigerated at all times — warmth reactivates fermentation
  2. 2Unpasteurized kombucha continues to ferment slowly even in fridge
  3. 3Check best-by date — taste gets more vinegary over time
  4. 4If a SCOBY forms on top, the kombucha is still safe but very active
  5. 5Do not freeze — kills beneficial probiotics and changes texture
