Why We Keep the Sugar Lower

By GingerBros Wellness May 14, 2026

Most of the sugar in our brew is eaten by the ginger bug during fermentation.

A typical can of commercial ginger ale or soda contains somewhere around 30–40 grams of sugar. To put that in perspective: the World Health Organization recommends adults keep "free sugars" under 10% of daily energy, roughly 50 grams, or about 12 teaspoons, and suggests that dropping to 5% brings further benefit. A single sweet soda can eat most of that allowance in one go. Worse, most so-called ginger "ale" is not even fermented; it is carbonated sugar water with ginger flavouring added. We take a fundamentally different approach.

The ginger bug eats the sugar

This is the quiet superpower of real fermentation, and it is worth understanding because it is genuinely different from how a diet soda is made. During our natural fermentation process, the wild yeast and bacteria in the ginger bug consume much of the white sugar we start with as their food, converting it into carbon dioxide (the bubbles), a trace of organic acids (the bright tang) and a cascade of flavour compounds. By the time we bottle, only a modest amount of residual sugar remains, just enough to balance the ginger's heat and sustain the natural carbonation.

In other words, the lower sweetness is not something we engineer out with chemistry at the end. It is something the microbes do for us, gradually, over a week. The drink tastes less sweet because it genuinely is less sweet.

Why we do not use artificial sweeteners

We could push the sugar number to zero with stevia, sucralose or aspartame. We choose not to, for a few reasons. Many artificial sweeteners carry a metallic or lingering aftertaste that fights the clean ginger flavour we work hard to build. There is also active scientific debate about how some non-nutritive sweeteners interact with the gut microbiome, and since our whole philosophy is built around a healthy ferment, adding ingredients that may disrupt gut microbes would be working against ourselves. We would rather let fermentation do the job and keep the ingredient list honest and short.

What this means for you

  • As a standalone drink, it satisfies a soda craving with a fraction of the sugar.
  • As a mixer, it will not bury your spirit under syrup, your cocktail tastes of ginger and citrus, not sugar.
  • For anyone watching their intake, it is a far gentler choice than a conventional ginger ale, without resorting to sweeteners.
Of course, moderation still matters, lower-sugar is not no-sugar, and it is still a treat. But it is a genuinely nice thing when the better choice also happens to taste better.
