What is kombucha?

Open tab
Kombucha is slightly effervescent, refreshing tea based drink. Originating from Asia, the history of kombucha dates back more than 2000 years. Its main ingredients are tea and sugar which are fermented with yeast and bacteria. The origin of the name, Kombucha, is uncertain. One legend says a Korean doctor named Kombu brought it to Japan in 414 AD after which kombucha was regularly carried and enjoyed by the samurai. Sure enough, it sounds like a legend, but then again the samurai were an interesting bunch. We watched the Last Samurai again but didn't see Tom sipping kombucha. They did enjoy tea though. That's always good. People should drink more tea.

What is SCOBY?

Open tab
Symbiotic Culture of Bacteria and Yeast, SCOBY is the mother of kombucha. All the yeast and bacteria contained in the mother convert tea, sugar and water into kombucha. Essentially, the floating pellicle you see on top of a kombucha vessel is what is called a "SCOBY".

Why does kombucha contain sugar?

Open tab
Sugar is what feeds the scoby. Often the kombucha mother doesn't eat up all the sugar leaving some residual sugar behind. The Good Guys kombucha has less than 5 g of sugar / 100ml while fruit juices and sodas often have 10 - 20 g of sugar / 100ml. In kombucha sugar is not added as a sweetener but for start the fermentation which results in healthy end products, such as organic acids and good bacteria.

Does kombucha contain alcohol?

Open tab
Through fermentation some of the sugar converts to alcohol, and alcohol then converts to vinegar. Trace amounts of alcohol is present in kombucha as a result of natural fermentation. The Good Guys kombucha has less than 0.5 % alcohol upon bottling.

Does kombucha contain caffeine?

Open tab

Why does The Good Guys kombucha need to be stored refrigerated?

Open tab

Our kombucha in glass bottles can get little bit wild if it stays in ambient temperature for too long. That is because it contains living yeast which may active in warm temperature, causing more than the desired level of bubbles in the kombucha. When it comes to The Good Guys glass bottled kombucha - store it in refrigerator. Our kombucha in cans may well be stored at ambient temperature due to gentle heat treatment which removes the yeasts. All the good bacteria are still present in the kombucha. In fact, each can has 2 billion living probiotics ready to make your gut feel great.

Can you enjoy kombucha during pregnancy?

Open tab
Just to be on the safe side with alcohol (<0.5%), we don't recommend kombucha during pregnancy.

How much kombucha should I drink per day?

Open tab
We recommend starting with baby steps. The effects of kombucha are individual - some fall in love with the taste, while others notice that it helps with digestion and overall gut health. It's a good idea to listen to your body and adjust your drinking behaviour accordingly. A bottle per day is a good start. Remember that there is no right or wrong way to enjoy kombucha. What feels good inside is the right way for you. Trust your gut feeling!

Is there added carbonation in The Good Guys kombucha?

Open tab
The Good Guys kombucha has both naturally occurring carbonation and slight added carbonation so that our brew is more consistently fizzy. That also means we can ferment longer, get residual sugars as low as possible, and minimize the amount of alcohol in the bottle.
