More and more local Kombucha companies are canning their Kombucha in aluminium cans. We have often contemplated to do the same, but believe that health benefits are compromised in the process. We asked Grok, an AI tool, for advice and this was the answer.
“The bigger issue with kombucha in cans is its fermentation. Kombucha is “alive” and can continue fermenting, producing CO2. In a sealed can, this could build pressure over time, especially if stored warm (above 40°F/4°C), potentially warping the can or causing leaks. Most commercial canned kombucha is pasteurized or stabilized to halt fermentation, but some brands market “raw” versions. If it’s raw, the can’s integrity and shelf life could be trickier to predict—check the label or ask the manufacturer about their process.”
Cans are lighter, possibly even prettier and more convenient, but if you are using Kombucha for its health benefits, you may be losing the full potential by drinking it from a can.
