And a recent study from The Royal Melbourne Institute of Technology (RMIT) has given us over 200 reasons to choose the real stuff.
Using metagenomic sequencing, a DNA-based approach to identify microbes, the study uncovered an incredible diversity of over 200 unique bacterial and yeast strains in Good Brew kombucha.
Most commercial kombuchas list only 1–4 strains, often added artificially after fermentation. This RMIT finding builds on published, peer-reviewed evidence and really highlights Good Brew’s transparency and leadership in microbiome support. It’s ideal for those interested in gut health, post-antibiotic recovery, fermented foods, and anyone seeking more than just another kombucha.
Why Microbial Diversity Matters
Our guts thrive on diverse microbial input. More strains mean better immune and digestive resilience.
Specific strains can even support mood regulation (via the gut-brain axis), reduce inflammation, and improve nutrient absorption. Research from Frontiers in Microbiology (2022) shows that probiotic diversity even improves gut ecosystem recovery after antibiotic use.
Why Most Kombuchas Miss the Mark
Many industrial kombuchas are pasteurised, killing most or all beneficial microbes. They might also be filtered, removing visible cultures and lowering microbial complexity. To extend shelf life, they’re often stabilised in a way that compromises probiotic survival.
What you’re left with is often a soft drink in disguise, not a living health food, containing as few as five lab-grown strains.
Real Kombucha Is Wild. And That’s a Good Thing.
Traditional fermentation fosters a balanced microbial community. Like kefir, sourdough, and raw sauerkraut, the health magic of kombucha lies in its natural complexity.
The RMIT study proves that Good Brew’s wild fermentation method yields unmatched diversity, all without artificial additions.
How to Tell If Your Kombucha Still Has Life
Here are some signs of a real, living brew:
What It Means for Your Gut Health
Regular exposure to broad-spectrum probiotics helps rebalance microbiomes disrupted by stress, antibiotics, or a poor diet. Unlike probiotic capsules with just 1–3 strains, Good Brew offers a living, full-spectrum solution.
It’s ideal for those seeking natural gut repair, immunity support, and stable energy without caffeine crashes.
The Brew That’s Backed by Science
Good Brew isn’t just marketed as “natural”. We have an RMIT-backed metagenomic analysis and a clinical human trial showing blood sugar benefits.
We’re committed to being Australia’s most studied kombucha.
Microbial complexity influences flavour, giving you nuanced sourness, soft effervescence, and an evolving taste profile over time. Every batch is slightly different, just like your gut.
Don’t settle for four strains and a fizzy label. Sip something real – and alive. Check out Good Brew’s traditionally brewed kombucha on our website today.
