Does Kombucha Need Air to Ferment?

Yes, kombucha needs air to ferment. Without air, the fermentation process can’t happen. Kombucha is a symbiotic culture of bacteria and yeast (SCOBY), and the SCOBY needs oxygen to live.

Oxygen is necessary for the growth of the SCOBY and for the fermentation of the kombucha.

Kombucha is a fermented beverage made from sweetened black or green tea. It’s rich in probiotics and has been shown to have various health benefits, including improved digestion and gut health. One of the most important aspects of kombucha fermentation is oxygenation, which helps to create the healthy bacteria that give kombucha its many benefits.

While some people believe that kombucha needs air to ferment properly, it’s actually not necessary. Kombucha can be fermented without oxygen, but it will take longer and the end result may not be as flavorful or as probiotic-rich. If you’re looking for a quick and easy fermentation process, it’s best to allow your kombucha to ferment with oxygen.

Kombucha Airlock Or Cloth

Kombucha airlocks are devices that allow carbon dioxide to escape from kombucha while preventing oxygen and other contaminants from entering. Airlocks can be made of plastic, glass, or metal, and usually have a one-way valve that allows gas to escape but not enter. Many kombucha brewers use airlocks during the fermentation process to prevent oxygenation and keep their brews healthy.

Airlocks are an important part of kombucha brewing, but they’re not the only way to keep your brew safe from oxygen. You can also use a cloth covering, which will allow carbon dioxide to escape while keeping out oxygen and other contaminants. Cloth coverings are typically made of cheesecloth or muslin, and they’re easy to find at most craft stores.

Whether you use an airlock or a cloth covering, it’s important to make sure that your kombucha is protected from oxygen during fermentation. Oxygen can cause off flavors in kombucha, so it’s best to avoid it if possible. By using an airlock or cloth covering, you can ensure that your kombucha stays fresh and delicious for weeks or even months!

Can I Brew Kombucha With an Airlock?

Yes, you can brew kombucha with an airlock. Airlocks are a common way to seal fermenting vessels, and they work just as well for kombucha as they do for other types of fermentation. In fact, using an airlock can help to prevent mold and other contaminants from entering your kombucha while it is fermenting.

Why Does Kombucha Need Oxygen?

Kombucha is a fermented beverage made from sweetened tea that’s been combined with a symbiotic colony of bacteria and yeast (SCOBY). During fermentation, the SCOBY consumes the sugar in the tea, which produces alcohol and other byproducts like carbon dioxide and acetic acid. The final kombucha product is slightly alcoholic, slightly acidic, and contains probiotics.

Oxygen is necessary for fermentation to occur. The bacteria in the SCOBY need oxygen to break down the sugars in the tea and create alcohol. If there’s no oxygen present, the fermentation process will come to a halt.

It’s important to note that while kombucha needs oxygen during fermentation, it doesn’t need oxygen once it’s bottled. In fact, too much oxygen can cause spoilage. Once kombucha is bottled, make sure to store it in a cool, dark place away from any sources of oxygen (like open air) to prevent it from going bad prematurely.

Do Scoby Need Oxygen?

It’s a common misconception that SCOBYs need oxygen to thrive, but this is actually not the case! SCOBYs are anaerobic organisms, meaning they don’t require oxygen to survive. In fact, oxygen can actually be harmful to SCOBYs, so it’s important to keep them in an oxygen-free environment.

Is Kombucha Ok If Not Fizzy?

Kombucha is a fermented tea that has been consumed for centuries in Asia. It is made by adding a symbiotic culture of bacteria and yeast (SCOBY) to sweetened tea, and allowing it to ferment for a period of time. The SCOBY consumes the sugars in the tea, and produces acetic acid, which gives kombucha its tart flavor.

During the fermentation process, kombucha also produces carbon dioxide gas. This is what gives kombucha its characteristic fizziness. However, if you allow the kombucha to ferment for a longer period of time, or bottle it without providing an outlet for the gas (such as using a swing top bottle), the carbon dioxide will be absorbed back into the liquid, resulting in a non-fizzy kombucha.

So, is kombucha OK if not fizzy? Yes! Non-fizzy kombucha is perfectly safe to drink, and still contains all of the beneficial probiotics that make kombucha so healthy.

So go ahead and give it a try – your gut will thank you!

Beginners Guide To Fermentation: Kombucha Making


Kombucha is a fermented beverage made from sweetened black tea. During fermentation, bacteria and yeast convert the sugars in the tea into alcohol and carbon dioxide. The carbon dioxide gives kombucha its fizzy quality.

Kombucha can be still or sparkling, and it’s often flavored with fruits, herbs, or spices. Some people believe that kombucha needs air to ferment properly, but this isn’t strictly true. While oxygen is necessary for the initial stages of fermentation, too much oxygen can actually inhibit bacterial growth and cause off-flavors in the final product.

It’s best to keep kombucha covered during fermentation to prevent oxidation.
