Introduction to Continuous Brew Kombucha
Continuous brew kombucha is a method of brewing kombucha that allows for a constant flow of fermented tea. This system is perfect for those who want to have a steady supply of kombucha without the hassle of batch brewing. In this article, we will cover the equipment needed, step-by-step setup, and pro tips for a successful continuous brew kombucha system.
Equipment List
- Continuous brew vessel (e.g., glass or food-grade plastic container)
- Kombucha SCOBY (Symbiotic Culture of Bacteria and Yeast)
- Starter tea (pre-fermented kombucha tea)
- Sweetened black or green tea
- Cheesecloth or a coffee filter
- Rubber band
- Tubing and valve (for continuous flow)
- Bottles for secondary fermentation and storage
Step six in the setup below is where that equipment list is misleading. Continuous brew does not use tubing and a valve in the way a siphon does: the vessel itself has a tap fitted near the base, and you simply draw finished kombucha out of it while the SCOBY and the bulk of the acidic liquid stay put. That single vessel is the entire system.

Why it fits
A two-gallon glass body with a tap near the base is exactly the arrangement continuous brew requires: draw off a quart, top it back up with cooled sweet tea, and the culture never gets disturbed or re-pitched. Two gallons is the practical minimum for the method, because the mature liquid you leave behind is what acidifies each new fill quickly enough to stay safe. The stand raises the tap so a bottle fits under it.
Limitations
The tap sits above the base, so yeast strands and sediment build up underneath it and eventually force a full clean-out. It is sold as a party dispenser, so treat the tap washer as a part to check and tighten before you trust it with a gallon of liquid on a counter.
Tap upgrade

Worth fitting before the first batch. Stainless is unbothered by kombucha's acidity, where a cheap plastic tap tends to seize or weep after a few months.
Bottles

For the secondary fermentation the FAQ mentions. Swing tops hold the pressure that builds when you bottle with fruit, which a screw cap on a repurposed jar will not.
Step-by-Step Setup
To set up your continuous brew kombucha system, follow these steps:
- Sanitize your equipment: Wash all equipment with hot water and vinegar to prevent contamination.
- Prepare the sweetened tea: Brew a gallon of sweetened black or green tea and let it cool.
- Add starter tea and SCOBY: Once the tea has cooled, add the starter tea and gently place the SCOBY into the liquid.
- Cover the vessel: Cover the top of the vessel with cheesecloth or a coffee filter, securing it with a rubber band.
- Wait for fermentation: Allow the mixture to ferment for 7-14 days, or until it reaches the desired level of sourness.
- Set up continuous flow: Once the fermentation is complete, set up the tubing and valve to create a continuous flow of kombucha.
Pro Tips for a Successful Continuous Brew
To ensure a healthy and thriving continuous brew kombucha system, follow these pro tips:
- Monitor the pH levels: Regularly check the pH levels of your kombucha to ensure it remains within the optimal range (2.5-3.5).
- Maintain temperature control: Keep the fermentation area at a consistent temperature between 68-85°F (20-30°C).
- Perform regular cleanings: Clean the equipment and vessel regularly to prevent contamination and mold growth.

That pro tip is the single most useful measurement in continuous brewing, because a vessel you keep topping up can drift sweet without tasting obviously wrong. This reads the 2.5-3.5 window directly.
Frequently Asked Questions
Here are some common questions and answers about continuous brew kombucha systems:
- Q: How often should I feed my SCOBY?
- A: Feed your SCOBY regularly by adding sweetened tea to the vessel.
- Q: What is the ideal ratio of starter tea to sweetened tea?
- A: The ideal ratio is 10-20% starter tea to sweetened tea.
- Q: Can I flavor my continuous brew kombucha?
- A: Yes, you can flavor your continuous brew kombucha with fruits, herbs, or spices during secondary fermentation.
