Lesson 01
Harvesting and handling raw honey
Pull, extract and jar honey that stays good indefinitely — and know the one moisture number that decides whether it keeps or ferments.
Honey is the only sweetener on this list that arrives finished. Bees bring in nectar at something like 70-80% water and dehydrate it down with wing fanning until it's around 17-18%. When a cell is done, they cap it with wax. That cap is the whole quality signal: capped honey is dry enough to be shelf-stable essentially forever, and uncapped honey in the same frame is not. A frame that's more than a third uncapped shouldn't be extracted with the rest — pull it, or let the bees finish it.
Above roughly 18.5-19% moisture, wild yeasts that live in honey naturally start to work and the jar ferments. It won't hurt you, it just isn't honey anymore. A refractometer is around thirty dollars and it removes the guessing entirely. The old shake test — tipping an uncapped frame hard over the hive and seeing if nectar flings out — still works as a field check: if it rains nectar, it isn't ready.
The harvest itself is one long sticky afternoon. Brush or blow the bees off the super, get it inside somewhere bees can't follow, and warm the frames to around 80-90°F so the honey flows. Uncap with a hot knife or a scratcher, spin it in an extractor, then strain through a coarse mesh — 400 to 600 micron is plenty — to take out wax bits and the occasional bee leg. Do not filter finer than that unless you want to strip the pollen out, and do not heat it above about 105°F. Heat past that point destroys the enzymes and the aromatics that make your honey taste like your place instead of a supermarket bear.
Then let it settle in a bucket for a day or two so the air bubbles rise, skim the foam off the top, and jar from the bottom valve. Glass or food-grade plastic, lids on tight, room temperature, out of the light. Never refrigerate honey — the fridge is exactly the temperature range that speeds crystallization. And crystallization isn't spoilage; it's what real raw honey does, and the speed depends on the nectar source. Clover and canola go grainy in weeks, tupelo and sourwood stay liquid for years. To reliquefy, sit the jar in water no hotter than 105°F and be patient.
Two safety notes that matter. Honey is not safe for infants under twelve months, because it can carry botulism spores that a baby's gut can't handle yet — that's a firm rule, raw or not. And leave the bees enough. Taking the fall harvest down to nothing and feeding sugar syrup all winter is how beginners lose colonies; most keepers leave a full deep of stores or more, depending on the climate.
Moisture target
17-18%. Above about 18.5-19% and the jar ferments.
Capping rule
Extract frames that are capped. Leave anything more than roughly a third uncapped on the hive.
Warming temperature
80-90°F for flow. Never above about 105°F — heat kills enzymes and aroma.
Straining
400-600 micron mesh. Finer filtration strips out the pollen.
Storage
Sealed, room temperature, out of light. Refrigeration only speeds crystallization.
Hard rule
No honey for infants under 12 months, raw or processed.
Do this
- Buy a refractometer before your first harvest. It's the cheapest tool that prevents a fermented batch.
- Pull only capped frames, and give partially capped ones another week on the hive.
- Warm the supers indoors to 80-90°F the night before you extract so the honey actually flows.
- Strain coarse, settle a day or two in a bucket, skim the foam, and jar from the bottom valve.
- Label jars with the month and the dominant bloom. Your spring honey and your fall honey are different products.
- Leave the colony generous winter stores before you take any for yourself.
Watch out for
- Extracting uncapped frames with the rest. One wet frame can push a whole bucket over the fermentation line.
- Heating honey to make it easier to strain. Anything much over 105°F costs you the flavor you did all this for.
- Fine-filtering to make it look clear. That's removing the pollen and most of the character.
- Storing honey in the refrigerator. It crystallizes faster there, not slower.
- Treating crystallization as spoilage and throwing it out.
- Giving honey to a baby under a year old, in any form.
