How Does Temperature Affect Kombucha?

Temperature plays an important role in brewing kombucha. Here’s what you need to know in order to ensure your homemade kombucha is brewing at its peak temperature!


When it comes to making kombucha, temperature and time both play important roles in the process. While many homebrewers focus on obtaining the perfect SCOBY or experimenting with flavor combinations, the often-overlooked element of temperature can significantly impact the outcome of your brew. In this blog post, we'll explore the ideal kombucha temperature, why it matters, and how it influences the taste and health benefits of your homemade kombucha.

Why It's Important to Get The Temps Right
The fermentation process of kombucha is a delicate dance between beneficial bacteria and yeast. The conductor of this dance is temperature. If you don’t get it right, your brew can taste sour, or worse—it can become moldy!

At higher temperatures, fermentation occurs more rapidly, potentially resulting in a faster brewing time. However, pushing the temperature too high can lead to an imbalance in the microbial community, affecting the taste and health benefits of your kombucha.

In the ideal temperature range, the SCOBY works harmoniously, producing a well-rounded brew with optimal levels of probiotics and other beneficial compounds. This balance contributes to the characteristic tangy flavor and the positive impact on gut health that kombucha is known for.

The Ideal Kombucha Temperature

The ideal temperature for brewing kombucha falls within the range of 75-85°F (24-29°C). This temperature sweet spot allows the symbiotic culture of bacteria and yeast (SCOBY) to thrive and ferment the tea effectively. Maintaining a consistent temperature within this range is crucial for achieving a balanced and flavorful brew.

What does higher temperature do to kombucha? 

Higher temperatures in kombucha brewing disrupt the delicate balance between yeast and bacteria, leading to an imbalance. This imbalance results in an increased yeast presence, contributing to higher alcohol content and an uneven taste profile. Additionally, excessively high temperatures can potentially kill off beneficial microbes, impacting the health benefits of the final brew.


But Wouldn't Faster Brewing Be  Better?

While a faster brewing time might seem appealing, it's important to note that rushing the fermentation process can compromise the quality of your kombucha. The flavors may become unbalanced, and the health benefits may not be as pronounced. Patience is key in the world of homebrewing, allowing the SCOBY to work its magic at its own pace.

What Happens When Kombucha Is Too Cold?

On the flip side, brewing kombucha at temperatures below 70°F (21°C) can slow down or even halt the fermentation process. This can lead to a weaker flavor profile and a brew that lacks the robust probiotic content that makes kombucha a health powerhouse. Cold temperatures may also increase the risk of contamination, as the SCOBY may struggle to outcompete harmful microbes.

Ways to Keep Your Kombucha Warm

Maintaining a consistent brewing temperature is essential for successful kombucha brewing. Here are some practical tips to keep your brew cozy:

1. Use a heating mat: Placing your brewing vessel on a heating mat with adjustable temperature settings can help regulate the temperature. I like using a  seed germinating mat.

2. Insulate your container: Wrap your fermentation vessel with towels or blankets to provide insulation and retain heat.

3. Choose a warm spot: Place your brewing vessel in a warm area of your home, away from drafts or cold spots.

Remember, the key to a successful kombucha brew lies in finding the right balance and creating a comfortable environment for your SCOBY to thrive.

Kombucha Brewing Temperature Matters

In conclusion, the temperature at which you brew your kombucha is a crucial factor that can influence both the taste and health benefits of your homemade concoction. Understanding the ideal temperature range, avoiding extremes, and exercising patience are vital for achieving the best results in your homebrewing journey.
