Unlocking the Sweet Secret: Decoding the Role of Sugar in Kombucha

Kombucha, a tangy and effervescent beverage, has gained popularity as a refreshing and probiotic-rich drink. While its distinct flavours and potential health benefits have captivated enthusiasts, the role of sugar in the fermentation process remains a subject of curiosity and debate. In this blog post, we look into the intriguing world of sugar in kombucha and explore its potential benefits for our well-being.

When we think of kombucha, we may wonder about its sugar content. It's true that kombucha starts with sweetened tea, but through fermentation, the sugar undergoes a significant change. During fermentation, the kombucha culture, known as the SCOBY, consumes the sugar as its food source. The SCOBY contains bacteria and yeast that convert the sugar into various beneficial compounds.

The yeast in the SCOBY breaks down the sugar molecules into alcohol and carbon dioxide through the process of fermentation. This natural fermentation is similar to what occurs when making bread or brewing beer. But here's where the magic happens—while the yeast produces alcohol, the bacteria in the SCOBY, specifically Acetobacter and Gluconobacter, convert the alcohol into organic acids, primarily acetic acid. This conversion gives kombucha its characteristic tangy flavour.

Through this symbiotic relationship between yeast and bacteria, the sugar content in kombucha decreases significantly as the fermentation progresses. The longer the fermentation time, the more sugar is consumed by the SCOBY. The result is a beverage with a considerably lower sugar content compared to the initial sweetened tea. The final product, due to the fermentation process, provides us with a significantly reduced amount of sugar and trace amounts of alcohol and a bounty of organic acids, enzymes, vitamins.

It's important to note that the exact sugar content can vary depending on factors such as fermentation time, brewing method, and the specific kombucha brand or recipe. But overall, kombucha is known for being relatively low in sugar compared to other sweetened beverages.

At Gather Brewing, we have found our sweet spot to be at around 3g/100ml, which is about 1/4 of the amount found in regular soft drinks. As a real craft brew kombucha we don’t use any fancy machinery or additives to produce our brew. This means that we don’t need to add any fake sugars to make our kombucha taste great. We utilise it’s base ingredients and balance it’s final composition. It does mean you need to keep it in the fridge, but that’s a tradeoff we’re willing to work with to produce a truely authentic, great tasting kombucha, right here in Adelaide, South Australia.

So, jump onto the store and grab yourself some of our deliciously wild flavours and remember that the sugar it started with has undergone a remarkable transformation. It has been converted into a myriad of beneficial compounds that contribute to the unique taste and potential health benefits of this delightful beverage.
