Meet the LAB

Guardians of Fermentation

Imagine a world invisible to the naked eye.

On the skin of a beetroot, within the folds of a cabbage leaf, upon a ripening apple, and in a single drop of morning dew, billions of tiny living beings quietly thrive. They are older than human civilizations, older than the first cities and the earliest written chronicles. For countless generations, they have worked silently alongside us, transforming ordinary vegetables into living treasures rich in flavor, aroma, and character.

These are the lactic acid bacteria, known simply as LAB.

Although the word “bacteria” often brings to mind something unwanted, these remarkable microorganisms are among humanity’s oldest allies. Long before microscopes existed, they were already helping people create fermented vegetables, sourdoughs, cheeses, and nourishing drinks.

The farmers and craftsmen of old did not know their names. Yet they understood that when vegetables were prepared with care and respect, nature would begin its mysterious work on its own. Inside wooden barrels and earthenware crocks, a quiet transformation would unfold - a true alchemy of life.

LAB bacteria feed on the natural sugars hidden within plants. In return, they produce lactic acid, a remarkable substance that preserves food, shapes its distinctive flavor, and creates an environment where unwanted microbes struggle to survive.

It is thanks to these invisible artisans that a humble beetroot can become a deep ruby-red drink, and a simple cabbage can transform into a fragrant ferment treasured across generations.

What makes this process even more fascinating is that fermentation resembles a carefully conducted orchestra. Not all bacteria arrive at the same moment. Some take the stage first, preparing the environment. Others follow, deepening the transformation. A final group refines the flavor, aroma, and character of the finished ferment.

Each has a role to play.

In the chapters ahead, we will meet these unseen craftsmen one by one. We will discover why some are masters of aroma, others guardians of stability, and still others responsible for the layers of flavor that are difficult to describe, yet impossible to forget.

For fermentation is more than a process.

It is a story of partnership between humanity and nature—a story that has been unfolding, uninterrupted, for thousands of years.

The First Alchemist

Every great transformation has a beginning. Before a ferment develops its depth of flavor and aroma, someone must take the first step. In fermentation, that role belongs to an invisible pioneer.

For a long time, it rests quietly on the surface of vegetables. When beetroot meets salt and water, its work begins. This is when the First Alchemist awakens.

Scientists call it Leuconostoc mesenteroides. It is the first to start fermentation, turning natural sugars into lactic acid and carbon dioxide. The gentle fizz and tiny bubbles are signs of its activity.

Its job goes beyond starting the process. It slowly reshapes the environment and prepares it for the bacteria that follow. At the same time, it makes life harder for unwanted microbes.

Many of the fresh and lightly fruity notes of young ferments come from its work. After a few days, it steps aside for the next microbial masters. Every fermentation story begins with the First Alchemist.

The Guardian of the Kingdom

Every kingdom needs a guardian. Once fermentation has begun, another bacterium takes over to bring stability and protection. This is the Guardian of the Kingdom.

Scientists call it Lactiplantibacillus plantarum. It consumes the remaining sugars and produces lactic acid with remarkable efficiency. As a result, unwanted microbes struggle to survive.

Unlike the First Alchemist, it is not an explorer but a builder. It strengthens the foundations of fermentation and helps create balance. Thanks to its work, ferments become stable and long-lasting.

Its greatest strength is resilience. It thrives in acidic and salty conditions where many other microorganisms cannot survive. For this reason, it often becomes the dominant force in fermentation.

Without it, fermentation might begin but could not endure. It transforms the first sparks of change into something lasting. By the end of its work, the kingdom stands strong.

The Gatekeeper

Once the fermentation kingdom is secure, another hero takes its place. Its role is not to build or explore. Its role is to protect.

Scientists call it Pediococcus pentosaceus. It works quietly and rarely attracts attention. Yet its contribution is extremely important.

It produces natural protective compounds known as pediocins. These help stop many unwanted microbes from gaining a foothold. As a result, the ferment can mature undisturbed.

The Gatekeeper focuses on defending what has already been built. Its vigilance helps preserve the balance of the entire process. Often, a guardian’s greatest success is that nothing goes wrong.

Unseen, patient, and dependable, it watches over the ferment as it matures. Thanks to its presence, the kingdom remains safe.

The Master of Essences

When fermentation becomes stable and secure, the final stage begins. This is when the Master of Essences appears. Its role is to give the ferment its character.

Scientists call it Limosilactobacillus fermentum. It does not build walls or open gates. It is the artist of the fermentation world.

Working slowly and patiently, it draws out subtle aromas hidden within the ferment. Delicate notes of fruit, spice, and fresh bread emerge through its craft. These aromas add depth and complexity.

It does not dominate or force change. Instead, it reveals what nature placed in the ingredients from the very beginning. Its work becomes noticeable only near the end of the journey.

When its task is complete, the ferment reaches its fullest expression. The First Alchemist started the transformation, the Guardian gave it strength, the Gatekeeper protected it, and the Master of Essences gave it a soul.

A Living Story

And so, the tale of the invisible Kingdom of Fermentation comes to an end.

The tale of the First Alchemist, who awakened the transformation.

The Guardian of the Kingdom, who gave it endurance.

The Gatekeeper, who watched over its safety.

And the Master of Essences, who bestowed upon it character and soul.

Yet in truth, their story is not over.

For what you hold in your hands is not simply a bottle of fermented drink. It is a living ferment. A small kingdom of nature, captured within glass.

Inside reside billions of beneficial lactic acid bacteria—the very same invisible beings that worked together for days and weeks to create the flavor, aroma, and character of this ferment.

They are still alive. They are still watching. They are still quietly carrying out their ancient craft.

That is why every living ferment is unique.

Over time, its flavor may deepen or become more expressive. Its aromas may evolve in subtle and unexpected ways. These gentle changes are a natural part of the story, because nature itself never stands still.

The temperature at which it is stored, the passage of time, and the conditions of its surroundings may all influence the continuing journey of the microorganisms that inhabit this invisible world.

This is why every bottle is far more than a finished product.

It is a moment captured within an ongoing process.

So when you open this bottle, remember: you are not simply tasting a fermented drink.

You are becoming part of a story that began thousands of years ago and continues to unfold in every drop.

Welcome to the Kingdom of Fermentation.
