What Are Live Cultures in a Probiotic Drink? A Plain-Language Guide
Introduction
The term 'live cultures' appears on everything from yoghurt to kombucha to health drinks - but few people actually understand what it means, how to evaluate whether a product genuinely delivers them, and why the delivery method matters. This guide answers all of those questions, using FERMA as a worked example of how live cultures should be produced and delivered.

The Fermentation Process
Live cultures - also called probiotics - are living microorganisms that provide health benefits when consumed in adequate quantities. In FERMA, the live cultures are lactic acid bacteria that develop naturally during the fermentation of fresh beetroot and carrot. During fermentation, these bacteria consume the natural sugars in the vegetable base, producing lactic acid (which gives fermented foods their characteristic tangy flavour) and multiplying to create a concentrated population of live microorganisms. FERMA's cold fermentation process preserves these bacteria in their fully active state throughout the production and bottling process.
Why 'Live' Matters - and How to Verify It
Not all probiotic drinks that claim to contain live cultures actually deliver them to your gut. Pasteurisation - the heat treatment used to extend shelf life - kills live cultures. Many commercial probiotic drinks are pasteurised after fermentation to ensure a longer shelf life, which means the bacteria listed on the label are dead by the time you drink them. Dead bacteria provide no probiotic benefit. FERMA is never pasteurised, which means every bottle you open contains the full population of live, active cultures produced during fermentation. The proof: FERMA requires refrigeration. If a 'probiotic drink' does not need refrigeration, its live cultures have been destroyed.

Why FERMA Does It Better
Small-batch cold fermentation: FERMA ferments in small batches at controlled low temperatures - never with added heat. This preserves more live cultures and a broader spectrum of fermentation-derived compounds than large-scale industrial fermentation.
No pasteurisation: Many commercial fermented drinks are pasteurised after production, killing the very bacteria that make them valuable. FERMA skips this step entirely, delivering every live culture to you intact.
Real ingredients only: No concentrates, no flavour extracts, no additives. The ingredients list is exactly what you see: fermented beetroot, fermented carrot, live cultures.
Frequently Asked Questions
How many live cultures does FERMA contain?
FERMA's live culture concentration is measured at the time of bottling and maintained through refrigerated storage. The exact CFU (colony-forming unit) count is available on the product label.
What strains of bacteria are in FERMA?
FERMA's live cultures are naturally occurring lactic acid bacteria derived from the fermentation of fresh beetroot and carrot. This produces a diverse, naturally-derived probiotic ecosystem rather than a single isolated strain.
How do live cultures survive stomach acid to reach the gut?
The fermentation matrix - the lactic acid, natural sugars, and food compounds surrounding the live cultures in FERMA - provides protection against stomach acid. This is why food-based probiotics often outperform isolated probiotic capsules in reaching the gut alive.
Should I take a probiotic supplement alongside FERMA?
FERMA provides a broad-spectrum, food-based probiotic that many nutritionists consider superior to isolated supplements. For specific therapeutic applications, a doctor may recommend additional targeted probiotics - but for general gut health, FERMA is an excellent standalone choice.
