What is fermentation? How we make our naturally fermented sodas
At Good Sodas, we believe that great taste starts with real processes—not artificial shortcuts. We've spent years perfecting our drinks and diving deep into the art of fermentation, a natural method that has been used for thousands of years.

So, what is fermentation?
Fermentation is a process where microorganisms like bacteria or yeast transform sugars into other compounds. In our case, we use lactic acid bacteria (LAB)—the kind naturally found in many traditional foods. These helpful bacteria convert sugars into lactic acid, creating a flavorful, tangy soda that’s not only shelf-stable but uniquely refreshing.
This is the same kind of process used in foods like yogurt, sauerkraut, and sourdough. But here at Good Sodas, we’ve taken that traditional method and applied it to our craft: fermented soft drinks made with care, science, and organic grapes and Danish apples.
Why fermented soda?
Fermentation helps preserve the natural flavor of fruit and adds complexity that you just can’t fake. We ferment apple juice concentrate, which is naturally rich in polyphenols—compounds linked to anti-inflammatory and antioxidant effects. Through fermentation, we actually enhance the nutritional profile of the juice, while keeping sugar levels reduced. That’s why we proudly offer reduced-sugar fermented sodas that taste clean, crisp, and vibrant.
And yes, every bottle is made without caffeine—our sodas are completely caffeine free, so you can enjoy them any time of day.
A soda unlike the rest - Good Sodas®
There are many soda brands out there, but very few take the time to ferment their drinks using lactic acid fermentation (also called LAB fermentation). We do, and here's why:
Because it makes a difference—not just in taste, but in quality. Our process naturally extends shelf life, improves flavor, and creates a product that’s as functional as it is enjoyable.
So if you’re looking for:
-
A fermented soda that’s non-alcoholic
-
A craft fermented beverage made without additives
-
An organic fermented soda that respects the tradition of fermentation
-
A soda without caffeine that still brings bold, complex flavor
What makes fermentation unique?
We don’t use artificial flavorings or carbonation shortcuts. Every batch is brewed slowly, relying on the natural activity of lactobacilli to create depth and balance. Once fermentation is complete, we gently pasteurize our sodas to stabilize flavor and ensure safety, while preserving many of the beneficial compounds produced during fermentation.
Even after pasteurization, many of the organic acids, short-chain fatty acids, and bioactive compounds created by our fermentation process remain active. These include:
-
Butyrate
-
Acetate
-
Propionate
-
Enzymes and organic
While we avoid health fads and buzzwords, we’re proud of the science and tradition behind what we do.
