The Problem with Batch Brewing
Most home brewers follow the traditional batch method: brew a full 4L batch, wait 7–10 days, bottle everything, and start over. This often creates fermentation gaps—periods where your kombucha supply runs low while the next batch matures.
With the iGulu Smart Brewer, you can transition to a continuous brewing workflow designed to maintain a steady, gap-free supply through structured fermentation management.
The 2L Harvest Weekly Cycle
The core principle is simple: harvest 50% of the volume, refill 50%, and maintain an active master culture.
Step 1: Equal-Pressure Harvesting
When your 4L batch reaches peak flavor balance, use the iGulu Equal-Pressure Filling Bottle Kit to transfer 2 liters into pressure-rated bottles.
Unlike gravity filling, equal-pressure transfer helps preserve carbonation during bottling, maintaining consistent fizz and mouthfeel.
Step 2: The 50% Refill
Immediately replenish the remaining 2L of active culture:
• Brew 2L of black or green tea
• Add 50–100g/L organic cane sugar
– 50g/L: drier, lower-sugar profile
– 100g/L: balanced sweetness and carbonation
• Cool to room temperature before refilling to protect the live culture
Step 3: Accelerated Fermentation (Typically 3–4 Days)
Because 50% of the active starter remains in the vessel, microbial activity remains high and the environment stays stable. In many cases, the new cycle reaches optimal balance within 3–4 days, depending on temperature and sugar ratios.
Kombucha Cost Breakdown (DIY Mode)
When sourcing tea and sugar in bulk, a typical 4L continuous brew cycle may cost approximately:
• Organic sugar: ~$2.50 per batch
• Bulk tea: ~$1.80 per batch
• Energy and water: ~$0.15 per batch
Total per 4L cycle: ~$4.5
Approximate cost per 16oz serving (ingredient cost only): $0.50
Retail kombucha often ranges from $3–$5 per bottle. Continuous brewing can significantly reduce per-serving costs for households that regularly purchase kombucha.
Why iGulu Supports Continuous Brewing
• Stable temperature control (typically 26–28°C) supports predictable fermentation.
• Closed system design reduces exposure to airborne contaminants.
• Integrated cooling allows chilled, ready-to-serve storage within the keg.
Maintenance & Best Practices
Every 2–3 months, perform a full reset:
• Empty and sanitize the keg
• Trim excess SCOBY growth
• Retain 1L of the previous batch as starter for the next cycle
Conclusion: Own Your Production
Continuous Brew Kombucha with iGulu. Adopting the continuous brew method with iGulu transforms kombucha making from a periodic batch process into a structured fermentation system. With consistent carbonation control, reduced fermentation gaps, and lower long-term beverage costs, iGulu becomes an efficient home fermentation infrastructure.
