How Long Does It Take To Make Kombucha?

Kombucha, the well-loved fermented tea, has become a favorite among health-conscious individuals due to its numerous benefits. A common query that arises is: how much time is needed to produce kombucha? In this article, we will walk you through the kombucha brewing process, discuss elements that affect brewing duration, and offer advice for crafting homemade kombucha.

Quick Answer

  • Total time required for kombucha production: The complete kombucha brewing process typically takes between 9 and 17 days, encompassing both fermentation stages.
Stage Duration Factors Affecting Duration
Primary Fermentation 7-10 days Temperature, SCOBY health, sugar and tea type
Secondary Fermentation (optional) 2-7 days Sugar content of flavorings, bottle type and seal, temperature
Total Kombucha Brewing Time 9-17 days Combined factors from both fermentation stages

The Kombucha Brewing Process

Primary Fermentation: 7-10 Days

To create kombucha, you will require sweet tea, a kombucha SCOBY (Symbiotic Culture of Bacteria and Yeast), and starter tea from either a previous batch or an unflavored store-bought kombucha tea. The initial fermentation kicks off when you introduce the kombucha culture to the sweet tea in a fermentation jar or brewing container.

Fermentation Duration

This first stage of fermentation usually takes about 7-10 days. The exact time relies on factors like ambient temperature and the condition of the kombucha SCOBY.

Elements influencing fermentation duration:

  • Temperature: Kombucha cultures perform optimally at room temperature (approximately 68-78°F or 20-25°C). Colder temperatures can decelerate the fermentation process, whereas warmer temperatures can hasten it.
  • SCOBY health: A robust, thick SCOBY will ferment kombucha more effectively than a thinner or weaker one. Over time, the formation of a baby SCOBY signals a strong, active culture.
  • Sugar and tea type: The variety of sugar (e.g., cane sugar, organic sugar) and tea (e.g., black tea, green tea) utilized can influence the fermentation process and the final taste.

Secondary Fermentation (optional): 2-7 Days

The secondary fermentation is an optional phase that involves adding flavor and carbonation to the kombucha. This stage is carried out in airtight bottles, separate from the initial brewing container.

Fermentation duration:

The secondary fermentation typically lasts 2-7 days. Factors such as temperature and the sugar content of the added flavorings will impact the time it takes.

Elements influencing fermentation duration:

  • Sugar content of flavorings: Added sugars in flavorings can accelerate the fermentation process and result in a fizzier kombucha.
  • Bottle type and seal: Employing airtight bottles is crucial for the secondary fermentation since they capture the carbon dioxide responsible for creating fizz.
  • Temperature: Similar to the primary fermentation, ambient temperature plays a role in the duration of the secondary fermentation.


What is the duration for making homemade kombucha?

The overall time needed to prepare homemade kombucha is typically between 9 and 17 days, which includes both the primary fermentation and the optional secondary fermentation stages.

What is the fermentation time for kombucha?

The primary fermentation usually lasts 7-10 days, while the optional secondary fermentation can take an extra 2-7 days.

What is the time required for kombucha to form a SCOBY?

A new SCOBY generally forms during the primary fermentation, which takes around 7-10 days. However, the formation time for a SCOBY can vary based on factors like temperature and the condition of the starter culture.


Grasping the duration required to produce kombucha is essential for a successful brewing endeavor. By taking into account factors such as temperature, SCOBY health, and sugar content, you can fine-tune your brewing process to craft the perfect kombucha tailored to your preferences. So, gather your fermentation jar, tea bags, and SCOBY, and start experimenting with your very own kombucha today!
