I have been seeing quite a bit of high moisture honey.
To be grade A, honey has to be 18.6% water content or less. I have tested many samples in the 18.8 - 20% range. Honey above 18.6% will ferment with time.
When I bring my honey home I put it in my honey house with a dehumidifier running for at least a week. This will lower the water content before I extract it.
It is hard to get the water content down after the honey is extracted.
If this is not an option, always extract the capped honey first, then the uncapped. Keeping them separate, then check the water content. I do check honey moisture content for free.
Always stir honey if it has sat for a week or so. Moisture will separate in honey and the higher water content can lay on top of a pail. By stirring it before a sample is taken, will be a more accurate sample.
