Honey moisture — extract, wait, or ferment risk
A refractometer reading is a number. This page turns it into extract / wait / danger using the bands US packers actually repeat. Then store the lot moisture on the HiveFlow harvest so you are not trusting a photo of the meter.
Not a lab. Calibrate the refractometer. Temperature compensation matters. 17.8% and 18.6% are widely taught US rules of thumb, not a federal statute on this page.
Under about 17.8% moisture, most hobby extractors pull. Between 17.8 and 18.6, wait on the super or dry the room. Above 18.6, fermentation risk climbs and you should not bottle as if it were finished honey.
HiveFlow harvest charts are useless if the lot was wet. Log moisture with the harvest weight. That is the whole loop: meter → this band → harvest record.
- Calibrate the refractometer with distilled water or the standard the unit shipped with.
- Sample honey at room temperature. Enter the percent.
- If the band says wait, give the super more time or a dehumidifier. Measure again.
- When you extract, log weight and moisture on the harvest in HiveFlow.
Questions people type next to HiveFlow
- What moisture should honey be for extraction?
- US hobby teaching: at or under ~17.8% is the comfortable extract band. 18% is a judgment call. Above ~18.6% is the ferment-risk band this calculator flags.
- Does HiveFlow replace a refractometer?
- No. The meter is the instrument. HiveFlow stores the reading on the harvest lot.
