What’s Inside Our Free Kombucha Guide.
This troubleshooting guide is built specifically for commercial kombucha producers who are tired of unpredictable batches holding back their growth and are ready to scale.
-
Keep ABV below 0.5% consistently with proven temperature, yeast management, and fermentation time protocols. Includes documentation strategies that make audits straightforward, not stressful.
-
Discover the root causes of flavour drift and how to eliminate them at scale. Learn why your starter tea ratio might be sabotaging consistency and get temperature control protocols for commercial fermenter systems.
-
Techniques to reduce sugar without compromising flavour or mouthfeel. Covers alternative sweetener strategies (stevia, erythritol, monk fruit) and how to balance consumer expectations with clean-label requirements.
-
Capacity planning that doesn't require new CAPEX. Learn how to maintain quality when moving from 100L to 1000L+ batches, plus supply chain strategies that prevent ingredient variability from derailing your line.
-
Troubleshooting protocols for off-flavours (vinegary notes, yeast funk, sulphur compounds), carbonation issues (flat product, bottle bombs, inconsistent fizz), and shelf-life extension without pasteurisation.
We’ve helped hundreds of kombucha producers unlock consistent, scalable production:
Alcohol Compliance
Helping multiple brands reduce their ABV in order to achieve regional listing.
Batch Consistency
Helping brands eliminate batch-to-batch taste inconsistency, delivering consistent flavour profiles and reducing consumer complaints.
Refermentation
Helping brands solve exploding bottles and volcanising issues, restoring consumer and retailer confidence.
A Guide Made for Commercial Kombucha Producers:
✓ Facing batch inconsistency, alcohol management issues, or scaling challenges
✓ Working with co-packers or operating their own production facilities
✓ Planning to expand into retail or struggling with consistency
✓ R&D managers, operations leads, QA professionals, or founders wearing multiple hats
If you're brewing 100+ litres per batch and production feels unpredictable, this guide will help you get the consistency you need.
