Kombucha is a fermented tea beverage known for its unique taste and potential health benefits. It is made by fermenting sweetened tea with a symbiotic culture of bacteria and yeast (SCOBY), which converts the sugar into alcohol, acids, and carbonation over time. This fermentation process creates a tangy, slightly effervescent drink with a variety of flavors, depending on the type of tea used and any additional flavorings like fruit, herbs, or spices. What is Kombucha and What Equipment are Needed to Brew Kombucha?
Often regarded as a health tonic, kombucha is rich in probiotics, antioxidants, and organic acids, which may support digestion, boost the immune system, and improve overall well-being. While its alcohol content is typically low (under 0.5%), kombucha also contains small amounts of caffeine, depending on the tea used. It has gained popularity as a refreshing, health-conscious alternative to sugary sodas, and is available in numerous flavors, often sold in bottles or cans for easy consumption.
Launching a commercial kombucha brewing project requires core equipment that can be divided into three key stages: brewing, bottling, and quality control & support.
1. Core Kombucha Brewing Equipment
This is the heart of production, determining capacity and basic quality.
Kombucha Tea preparation system: Used for batch brewing tea, dissolving sugar, and cooling, typically including heating tanks, filters, and heat exchangers.
Kombucha Fermentation tanks: Fermentation tanks must be made of **food-grade stainless steel (such as 304/316L)**. Capacities can range from hundreds to thousands of liters. High-quality tanks are equipped with **cooling jackets** for precise temperature control (usually 24-29°C). According to search results, a 1000L fermentation system can cost hundreds of thousands of RMB.
2. Filtration and Bottling/Packaging Equipment
This section affects the final product form and shelf life.
Filtration system: Removes yeast and bacteria residues after fermentation to ensure a clear and stable beverage before bottling.
Bottling equipment: Given that kombucha contains live cultures and carbonation, an isobaric filling machine (similar to beer bottling principles) is recommended to minimize oxidation and retain carbonation. The equipment needs to be adaptable to various packaging types, such as glass bottles.
Labeling and packaging equipment: Used to complete product labeling and outer packaging.
3. Quality Control and Auxiliary Support Systems
Ensuring safe, consistent, and efficient operation.
Quality control equipment: pH meters (to monitor the fermentation endpoint; a safe pH is usually below 4.2) and **refractometers** are essential.
Cleaning-in-Place (CIP) system: Automated cleaning and disinfection of fermentation tanks and pipelines is a crucial investment to ensure food safety and prevent microbial contamination.
Refrigeration and storage: Includes temperature control for the fermentation workshop and cold storage (for terminating fermentation and storing finished products).
