Kombucha Overview
Kombucha is a drink made from the fermentation of tea leaves and sugar, usually containing beneficial probiotics, yeast, and acids. Its history can be traced back to China and Russia thousands of years ago, but its popularity has increased significantly in recent years and has become one of the representatives of healthy drinks.
The main ingredients of Kombucha include:
- Tea: Traditional Kombucha uses black tea or green tea, and other teas such as white tea and black tea can also be used.
- Sugar: White sugar, brown sugar, honey, etc. are all common sugar sources for yeast and bacteria fermentation.
- SCOBY: It is the core of Kombucha fermentation and contains a variety of probiotics and yeast.
Basic kombucha brewing supplies
Fermentation tanks
- Stainless steel fermentation tank (such as 316 stainless steel): not easily corroded by acids, suitable for commercial production.
- Glass jars: transparent to observe the fermentation process, will not react with acidic liquids (such as wide-mouthed glass jars, and glass fermentation tanks).
- Plastic containers: must be food-grade (such as HDPE or PP materials), but long-term use may affect the flavor.
SCOBY
- SCOBY: The key to kombucha fermentation, you can cultivate it yourself or buy it.
- Starter Tea: This is fermented kombucha, which helps the new tea to acidify quickly and prevent contamination by bacteria.
PH test paper
Monitoring the acidity level of kombucha is essential to ensure safe fermentation. Using PH test paper can accurately detect the pH value during the brewing process to ensure that it is maintained within the safe range of 2.5 to 3.5. This acidity level not only inhibits the growth of harmful bacteria but also ensures the stability of the flavor and quality of kombucha.
Bottling equipment
After the kombucha is fermented, it needs to be put into bottling equipment for secondary fermentation. It is recommended to use a glass bottle with good sealing performance and avoid contamination. Common choices include flip-top bottles and standard screw-top glass bottles. Among them, flip-top bottles are popular because they are easy to operate and are especially suitable for secondary fermentation.
Temperature control equipment
Kombucha ferments best within a specific temperature range, usually between 68° and 85°. Temperature fluctuations can significantly affect the fermentation process, affecting flavor and quality. To ensure a stable brewing environment and obtain consistent fermentation results, using temperature control equipment or fermentation heaters is an ideal solution.
Filter
After each use of the SCOBY, you can use a filter to gently clean the surface of the SCOBY to remove attached tea residues or other impurities, keeping the SCOBY clean for the next use.
Cleaning Equipment
Cleaning and disinfecting equipment is very important in the kombucha brewing process because it ensures a sanitary fermentation environment and avoids contamination and bacteria. Use a soft brush or sponge to clean equipment such as fermentation containers, bottles, funnels, etc. Avoid using cleaning tools that have strong odors or leave residue.
Common Kombucha Brewing Methods
Traditional Bottle Fermentation Method
Traditional bottle fermentation is the most common brewing method. This method puts the fermented kombucha into the bottle and allows it to ferment further at room temperature, which usually results in stronger bubbles and flavor.
Steps:
- Prepare tea, sugar, and SCOBY.
- Brew tea with hot water, add sugar and wait for it to cool to room temperature.
- Mix the cooled tea with SCOBY and pour it into a glass bottle.
- Seal the bottle mouth with a cloth or paper towel to prevent dust from entering, and ferment in a warm place.
- Ferment for 7-14 days, and decide whether to stop fermentation based on personal taste and fermentation degree.
Advantages:
- Traditional brewing methods can better control the fermentation time and adjust the taste.
- You can get a richer flavor level, suitable for people who like a strong taste.
Fast fermentation method (cold fermentation method)
To speed up the brewing process, some people choose to use the fast fermentation method (cold fermentation method). This method shortens the fermentation time by controlling the temperature.
Steps:
- Prepare the tea liquid and SCOBY according to the traditional method.
- During the fermentation process, place the brewing container in a lower-temperature environment (such as a refrigerator or a lower-temperature indoor environment).
- Fast fermentation can usually be completed within 3-5 days, which is suitable for people who need to drink urgently.
Advantages:
- A shorter fermentation time is suitable for busy or impatient people.
- Fermentation in a low-temperature environment helps to preserve the fresh taste of tea.
Segmented fermentation method
The segmented fermentation method is to ferment kombucha in multiple stages, with slightly different temperatures and times in each stage. Usually, this method can better adjust the flavor and taste.
Steps:
- Mix the tea liquid with SCOBY for initial fermentation (5-7 days).
- During the fermentation process, the temperature can be adjusted or the fermentation time can be changed according to personal taste needs.
- After fermentation is completed, the bubble feeling and flavor depth can be controlled by segmented fermentation.
Advantages:
- Adjustable flavor and taste, suitable for people who pursue personalized taste.
- Multiple experiments with different teas and sugar sources can obtain more unique flavors.
How to choose the best kombucha brewing method for you?
Time requirements
If you are very busy and don’t have much time to wait for a long fermentation, the rapid fermentation method may be more suitable for you. This method uses low-temperature fermentation and can be completed in a shorter time.
Taste
If you like a strong and sour taste, the traditional bottle fermentation method may be more suitable because it can provide richer flavor and stronger bubbles. If you like a lighter taste, you can choose the staged fermentation method and gradually adjust it according to your taste.
Health
The most important health value of kombucha lies in the activity of its probiotics and yeast. If you want to get more probiotic benefits from kombucha, the traditional fermentation method usually can better play these effects.
Usage scenarios
If you plan to brew kombucha in large quantities, using the traditional bottle fermentation method may be more efficient, especially if you need to brew multiple bottles. If you are making it on a small scale for individuals or families, you can try the rapid fermentation method or the staged fermentation method and adjust it according to the number of people and taste.
FAQ
How long does it take for kombucha fermentation equipment to complete fermentation?
The fermentation time of kombucha is usually 7 to 14 days, depending on the temperature, sugar content, and type of tea. Higher temperatures and more sugar will speed up the fermentation process, while lower temperatures and less sugar will prolong the fermentation time.
How to control the temperature of kombucha fermentation equipment?
Kombucha fermentation equipment is usually equipped with a temperature control system that can set the temperature range between 24-30°C. It is very important to maintain a constant temperature and avoid large temperature fluctuations, otherwise, it may affect the fermentation quality.
How many SCOBYs are needed in the equipment?
Each batch of fermentation usually requires one active SCOBY as the starter strain of fermentation. Depending on the size of the fermentation container, the number of SCOBYs may need to be adjusted. Generally speaking, one SCOBY can adapt to the fermentation of 1-5 liters of liquid.
What are the requirements for the material selection of kombucha fermentation equipment?
