The Truth About Pasteurised Kombucha
Most kombucha is dead
before it reaches you.
We keep ours alive. Here's the truth about pasteurisation — and why it changes everything about what's in your bottle.
What pasteurisation actually does to your kombucha
Walk into most supermarkets and you'll find shelves of kombucha. It looks the part. It's labelled with words like "probiotic" and "gut health." But here's what most brands don't tell you: the majority of commercial kombucha is pasteurised — heated to high temperatures to extend shelf life and standardise taste.
The problem? Pasteurisation kills living cultures. The probiotics, the beneficial yeasts, the organic acids that make fermented drinks so powerful for your gut — destroyed in the process. What's left is a flavoured, carbonated drink that looks like kombucha but functions like a soft drink.
Why does this matter? The health benefits of kombucha come from its living cultures — the active probiotics and organic acids produced during fermentation. Without them, there is no gut benefit. You're left paying a premium for something that doesn't deliver.
We brew with whole, real teas — black, green, rooibos, honeybush, yerba mate and more. No concentrates, no shortcuts. The tea base determines the depth, flavour and antioxidant content of every batch.
✓ Whole leaf teas onlyA living SCOBY (symbiotic culture of bacteria and yeast) is added to the sweetened tea. Over up to 30 days, it slowly converts sugars into beneficial organic acids, probiotics and B vitamins. Most brands stop at 7–10 days. We don't.
✓ Up to 30-day fermentation ✗ Industry standard: 7–10 daysReal South African botanicals — buchu, rooibos, honeybush, sceletium and more — are added at this stage. No flavour concentrates. No synthetic ingredients. What goes in is exactly what it says on the label.
✓ Indigenous botanicalsBottled and left to naturally carbonate in a second fermentation cycle. This produces its own CO₂ — no artificial gas is added — and makes the kombucha even richer in beneficial yeasts and cultures.
✓ Naturally self-carbonated ✗ Most brands: CO₂ injectedWe never heat-treat our kombucha. Every bottle leaves our brewery raw, alive and unfiltered — exactly as it was intended to be. The living cultures remain active all the way to your glass.

Why we've never taken the shortcut — and never will
Tea of Life was founded in 2015 by Elizabeth Gunther, a Type 1 diabetic who understood better than most what goes into your body actually matters. From day one, the commitment has been simple: make kombucha the way it was meant to be made — raw, alive and slow fermented.
That means longer fermentation times. Smaller batches. Higher standards. It means your Tea of Life kombucha arrives at your door with its living cultures fully intact, doing exactly what fermented drinks are supposed to do for your gut.
Because a living drink should actually be alive.
