How Long Does Kombucha (store-bought, opened) Last? — Shelf Life & Storage Guide

Kombucha (store-bought, opened) lasts 7-10 days in the fridge. Complete shelf life, storage tips, and spoilage signs. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Refrigerator: 7-10 days. Freezer: Not recommended. Pantry/Counter: 1-3 months (unopened, pasteurized). Category: Condiments. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: 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. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Keep refrigerated at all times — warmth reactivates fermentation. Unpasteurized kombucha continues to ferment slowly even in fridge. Check best-by date — taste gets more vinegary over time. If a SCOBY forms on top, the kombucha is still safe but very active. Do not freeze — kills beneficial probiotics and changes texture. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
