How to track specific gravity in kombucha

Record original and later gravity readings

A gravity trend is more useful when the starting point is captured. BrewLogs supports starting gravity and later specific gravity readings inside batch logs.

Use estimated ABV carefully

Estimated ABV from gravity readings can support production review, but it should be treated as an estimate. Breweries remain responsible for any required alcohol testing, labeling, and compliance decisions.

Keep gravity beside pH and temperature

Gravity movement makes more sense when pH, temperature, and notes are available beside it. BrewLogs keeps those measurements in one batch record instead of splitting them across different sheets.

Document the basis for each estimate

When a team discusses estimated ABV, the record should show which gravity readings were used and whether the estimate has enough data behind it. That transparency helps brewers avoid treating an estimate as more precise than it is.

BrewLogs presents estimated ABV as operational context. The brewery should still use appropriate external testing whenever verified alcohol content is required.
