Measure Smarter. Ferment Better. Bottle with Confidence.
Kombucha fermentation is a dynamic, living process that evolves continuously. Even small changes in pH, sugar levels, or fermentation can have a noticeable effect on the outcome. Without clear visibility into what’s happening inside the brew, producers often rely solely on experience, taste, and timing. Fermentation, however, doesn’t need to rely on intuition alone. With EasyDens, pH2Go, and the Alcohol Meter, you can monitor essential parameters like extract concentration, ABV, and pH, and gain a deeper understanding of your fermentation process. These measurements help you better understand how your brew is developing and give you more control, from fermentation to the final bottle.

Keep Fermentation on Track
Kombucha starts with sweetened tea and a SCOBY - a symbiotic culture of bacteria and yeast. When fermentation starts the yeasts break down sugar, forming CO₂ and alcohol. With EasyDens, you can track density and extract concentration over time to see how sugar levels change and how actively the brew is developing, with estimated results for ABV and attenuation.
Monitor pH Progress
As sugar decreases, bacteria convert alcohol into organic acids, causing pH to fall. With pH2Go, you can check that the brew drops below pH 4.5, follow fermentation progress, and troubleshoot batches. A falling pH shows activity, while an unchanged pH may indicate the process is not progressing.
From Final Taste to ABV Verification
At the end, the balance of sweetness, acidity, and alcohol defines quality. Since kombucha is often a low-alcohol drink, the Alcohol Meter helps you check whether the ABV matches your target in the finished beverage.

Brew Meister App: Measure. Track. Improve.
Brew Meister transforms your measurements into clear, actionable fermentation insights. By connecting EasyDens, you can monitor the extract levels and follow each stage of fermentation with precision. ABV and attenuation are calculated automatically from your original and final gravity – no spreadsheets, no manual math. Pair with pH2Go and acidity trends appear alongside your density curve, giving you a complete picture of your kombucha’s development.
The Alcohol Meter gives you a reliable ABV in finished kombucha in seconds – even in complex, sugar-containing brews where density alone isn't enough. All data is automatically saved in organized batches and securely stored in the Meister Cloud, making it easy to access, review, and manage your fermentation process anytime from any device.
Key Measurement Parameters for Kombucha Production
Precise kombucha production depends on accurate measurement of fermentation parameters.
✓ EasyDens measures the density of your brew with high precision and an accuracy of 0.3 °Brix and automatic temperature compensation, enabling reliable fermentation tracking.
✓ SmartRef measures the refractive index of your brew. Combined with EasyDens, it forms the Alcohol Meter. That is giving you direct ABV measurement in finished kombucha with an accuracy of ±0.5 %v/v.
✓ pH2Go delivers fast and precise pH readings with an accuracy of ±0.02 pH using just 0.5 mL of sample, ensuring optimal acidity control. Its robust, glass-free ISFET sensor offers long-term durability, easy cleaning, and dry storage, making it ideal for everyday use.

FAQs
Can I measure the ABV of hard kombucha with the Alcohol Meter?
Yes. The Alcohol Meter can measure the ABV of finished kombucha within a range of 0 - 7 %v/v.
Which parameters are important for kombucha production?
Key parameters in kombucha production include extract content (°Brix), ABV, and pH. The extract changes indicate fermentation progress, alcohol defines the final product, and pH reflects acidity and stability. Monitoring these values helps ensure consistent quality and better control over fermentation.
Which instruments can I use to measure extract, pH and ABV?
EasyDens is used to monitor fermentation by measuring the extract content, while also providing an estimate of alcohol levels based on density changes. For more precise ABV measurements in final Kombucha, it can be paired with SmartRef. To track acidity throughout the process, pH2Go is used to measure pH values.
How can I track the fermentation progress?
Use EasyDens to monitor your kombucha by measuring its density. As fermentation progresses, density (g/cm³) and extract content (°Brix) decrease due to changes in sugar, ABV, and acids. This gives you a simple, data-driven way to follow fermentation day by day.
