Kombucha brewing is a process full of variations, offering you flexibility in how you create your favorite drink. Whether you’re a beginner starting with batch brewing or an experienced brewer exploring continuous brewing, understanding the different techniques can help you refine your process and improve the flavor and quality of your kombucha. 

In this guide, we’ll cover the key brewing techniques, from managing temperature to choosing between batch and continuous brewing, as well as cleaning and sanitation practices. If you’re looking to elevate your kombucha brewing, this comprehensive overview will get you started on the right path. 

Batch Brew vs. Continuous Brew: Which One is Right for You? 

One of the first choices you’ll make as a kombucha brewer is deciding between batch brewing and continuous brewing. Each method has its benefits and drawbacks, depending on your goals and brewing preferences. 

  • Batch Brewing: As the name suggests, this method involves making kombucha in separate, individual batches. After each brew, the kombucha is bottled, and a new batch begins. Batch brewing allows more control over flavor development and fermentation timing. It’s perfect if you want to experiment with different flavors and brewing cycles. 
  • Continuous Brewing: This method keeps the brewing process going without starting and stopping. A larger container with a spigot is used, and kombucha is drawn off from the bottom as it finishes fermenting. Fresh sweet tea is added to keep the process going. Continuous brewing can produce a steady supply of kombucha, making it great for high-volume drinkers, but it may result in a faster fermentation process, which can be harder to control.

Temperature Control and Location Considerations 

Temperature plays a huge role in kombucha fermentation, influencing the speed and quality of the brew. Your fermentation environment needs to be within a specific temperature range—ideally between 70°F and 85°F. Warmer temperatures will speed up fermentation, while cooler temperatures slow it down. 

In addition to temperature, the location of your brewing vessel is crucial. It’s best to place your vessel in a well-ventilated area, away from direct sunlight and harsh chemicals. Maintaining a stable temperature without drastic fluctuations helps ensure a smooth fermentation process.

Cleaning and Sanitizing Materials: Keeping Things Clean 

Kombucha is a living, fermented drink, which means sanitation is key to keeping harmful bacteria at bay. However, you don’t need to go overboard with sterilizing your equipment like you would with beer brewing. Simple cleaning methods are sufficient. 

  • Cleaning Your Brewing Equipment: Hot water and a non-abrasive sponge are usually all you need to clean your vessels, bottles, and caps. Avoid using antibacterial soaps or harsh cleaners, as they can leave residues that affect your brew. You’ll want to ensure that your sponges and cloths are clean and mold-free, too. 
  • Why Vinegar is Not Necessary: Some brewers recommend using a vinegar rinse to clean kombucha materials, but this practice isn’t necessary—and may even harm your SCOBY over time by turning it into a vinegar culture.

Flavoring Your Kombucha: Unlock Endless Possibilities 

One of the joys of brewing kombucha is the endless flavor combinations you can create during the second fermentation. After the first fermentation phase, you can add fruits, herbs, spices, and more to create your desired flavor. 

When it comes to flavoring, fresh fruit purees tend to produce the best carbonation, as they provide ample sugars for the yeast to convert into CO2. However, you can experiment with dried fruit, herbs, and store-bought juices to achieve different flavor profiles.
