You don’t need a lot of time or money to produce kombucha at home that has an incredible quantity of fizz. In order to get this project started, all you’ll need is some decent glass jars and bottles, some tea bags, and some sugar.

Kombucha should be fermented in a large, airtight container for the first several days. During the second fermentation, the kombucha is given a carbonated flavour by putting it in fermentation-safe bottles and corking it. Carbon dioxide cannot escape as a consequence of this, and the beverage is left with a frothy appearance. Choosing the glass bottle wholesale is perfect for the same.

Today, we’re going to talk about the second fermentation, and specifically, what is “fermentation-grade bottle?” Obviously the glass jars supplier is an important one here.

Why You Need Good Bottles for Fermenting

We must use fermentation-specific bottles while preparing kombucha to ensure the beverage’s integrity throughout the fermentation process. When crushed, the liquid retains all of its carbonation, making this kombucha significantly more carbonated than other varieties.

The bottle’s quality has a direct impact on both safety and ease of use. Even though explosions are very rare, they may still happen, the danger can be reduced by utilising fermenting-specific bottles. In the plastic bottle factory such bottles are not made.

Kombucha Bottle Characteristics

Glass: When it comes to making beer, glass is by far the most used material. Unlike metals, it does not react with the very acidic kombucha, is scratch resistant (unlike plastic), and has no components that may be toxic (such as lead in ceramic, BPA in plastic, or heavy metals in metal). Even though ceramic or porcelain may be used for brewing, it must be safe for ingestion. So the plastic jug is not the right option here.

During the second fermentation, the kombucha has to be carbonated, thus the bottles must be airtight. Because they have a rubber seal that stops air from escaping, swing-top bottles are suitable for this purpose.

In the Face of Pressure, Maintain Your Stability. Yeast and bacteria eat the sugars in the tea and release carbon dioxide as they do so. As a result of the lack of a vent for the carbonation, pressure will begin to build up within the bottles. As a result, it is essential to utilise bottles that can withstand the pressure generated by the fermentation process. These have more durable caps and thicker glass layers. You should aim for 58 psi of pressure. The glass container manufacturer companies are important here.

Bottles are not recommended

There are a few things to keep in mind while searching for the best kombucha bottles. As a result of its permeability and the potential for microbial contamination, plastic should be avoided as a building material. Metal should also be avoided, since it may react with the kombucha and release harmful compounds into the finished product. The use of crystal and ceramics not intended for culinary use should also be avoided because of the possibility of lead contamination.


Avoid “ornamental” bottles, which may seem exquisite and be perfect for serving water at fancy dinner parties but are not good for kombucha fermentation because of the pressure they produce. Mason jars aren’t great for making kombucha since they don’t completely shut out the air.
