01
Choose a realistic sweetness target
Dry, balanced, and sweet targets set expected residual sugar ranges rather than exact lab outcomes.
Treat this as process planning, then calibrate with your own fermentation logs.

Sugar Calculator
Estimate total, consumed, and residual sugar for dry, balanced, or sweet targets — so you can plan flavor and second-fermentation pressure with confidence.

Your sugar plan
L
Dry, balanced, and sweet set expected residual sugar ranges, not lab-exact outcomes. Warmer, longer fermentation consumes more sugar.

Sweetness target balanced
Residual sugar is total sugar minus what the SCOBY consumes. Use it as a process-control signal for taste and second-fermentation pressure — not a lab-certified nutrition figure.
Sugar planning guide
Plan sweetness with fermentation reality.
Use the calculator to estimate sugar outcomes, then connect those numbers with flavor goals, timing, and safe second-fermentation planning.
Dry profile Low
Leans tart and crisp, with less remaining sweetness.
Balanced profile Mid
A practical middle point for flavor and pressure management.
Sweet profile High
More sweetness can mean faster carbonation in 2F.
Residual sugar math total − consumed
This estimate helps you predict sweetness and pressure behavior. Use it as a process-control signal, not a lab-certified nutrition number.
02
Understand what each target implies
Dry targets assume higher sugar consumption before bottling, with a sharper acid-forward finish.
Sweet targets leave more residual sugar and can push faster pressure buildup in second fermentation.
Residual sugar by target (approx.)
Dry → ~12% of starting sugar remainsBalanced → ~20% remainsSweet → ~30% remainsWarmer + longer → less residual across all
03
Consumed vs residual sugar
Consumed sugar drives acid and gas production during fermentation while residual sugar shapes final taste.
Both values matter for flavor, stability, and second fermentation pressure behavior.
04
Temperature changes sugar conversion speed
Warmer fermentation generally consumes sugar faster and can move batches from balanced to dry sooner.
Cooler fermentation often leaves more residual sugar at the same day count.
05
Use repeatable measurement points
Take readings at consistent times and temperatures to make comparisons useful across batches.
Even simple consistent logging gives better process control than guessing from taste alone.
06 Plan ahead
Plan 2F pressure from residual sugar
The more fermentable sugar that remains at bottling, the faster pressure can rise in closed bottles.
Use your sugar estimate with the second fermentation calculator to reduce over-carbonation risk.

Kombucha sugar & sweetness questions
Common questions about residual sugar and target profiles.
How much sugar is left in finished kombucha?
Residual sugar depends on initial load, temperature, fermentation duration, and SCOBY activity.
Is dry kombucha always low sugar?
Usually lower than sweet targets, but exact values require process consistency and measurement.
Does warmer fermentation consume sugar faster?
Yes, warmer conditions generally increase fermentation speed and sugar consumption rates.
Can I compare sugar across batch sizes?
Yes. The calculator normalizes by volume so concentration comparisons remain meaningful.
