Frequently Asked Questions

What's the difference between expiration and best quality dates for Kombucha?

Kombucha does not have a strict expiration date like perishable foods. Instead, it has a 'best by' date, which indicates the period during which the drink is expected to retain its optimal flavor and quality. Over time, kombucha may continue to ferment in the bottle, leading to increased carbonation and acidity. While kombucha may still be safe to consume after the 'best by' date, the taste and quality may deteriorate. It's recommended to consume kombucha within a few months of purchase for the best flavor experience.

How can I tell if Kombucha has gone bad?

To check if Kombucha has gone bad, look for mold growth on the surface, a fizzy or vinegar-like smell, or a slimy texture. If you notice any of these signs, it's best to discard the Kombucha to avoid consuming spoiled product.

What are the food safety risks with Kombucha?

Kombucha is a fermented tea drink made by combining tea, sugar, and a symbiotic culture of bacteria and yeast (SCOBY). While kombucha is generally safe to consume, there are some potential risks associated with homebrewed kombucha if not prepared properly. The main risk is contamination from harmful bacteria or mold, which can lead to foodborne illnesses. To minimize these risks, it's important to ensure proper sanitation of equipment, use sterile containers, and monitor the fermentation process closely. People with compromised immune systems, pregnant women, and young children should be cautious when consuming kombucha.

What are some pro tips for storing Kombucha?

To store kombucha properly and maintain its quality, it is best to keep it refrigerated at all times, even before opening. Refrigeration slows down the fermentation process, helping to preserve the flavor and carbonation of the drink. Once opened, tightly seal the bottle or container to prevent excess carbonation loss and contamination. Avoid exposing kombucha to direct sunlight or extreme temperatures, as this can affect its taste and quality. It's also recommended to consume the drink within a few days of opening for the best taste experience.
