🐝 Harvesting

There is exactly one reliable ripeness test in beekeeping, and the bees perform it for you. Kenyan extension practice puts it plainly: harvest combs that are three quarters or more sealed or capped full of honey.

Understand why that works, because once you understand it you will never need anyone to tell you when to harvest again. Nectar comes into the hive as a thin, watery liquid. The bees fan it, move it between cells, and drive water out of it until it is thick enough that it will not ferment. Only then do they lay a wax capping over the cell. The capping is a seal placed by the colony to say: this one is finished. The wax capping is the bees' own moisture certificate, and it is free.

So the rule is simple. Capped comb is ripe honey. Uncapped comb is unfinished nectar, it carries too much water, and it will ferment in your bucket. Three quarters or more capped is the working threshold. A comb that is half capped is telling you to come back.

Now the second timing question, which is not about the comb but about the year. Harvest at the end of the flow, before the dearth bites. In an African apiary the year runs rains, flowering, main flow, dearth, and the honey in the hive at the end of the flow is the colony's food for the months when nothing is flowering. Harvest too late, deep into the dearth, and you take the stores the colony needed to survive. That colony will either starve or abscond, and absconding means you lose the whole colony, brood and all, not half of it. Harvesting into a dearth is one of the commonest causes of colony loss in African beekeeping.

The third timing question is the time of day. Kenyan practice harvests from 5.30 p.m. to 7.30 p.m. That is late afternoon into dusk. Two things are true at that hour. The foragers are home, so you are not stranding thousands of bees who return to find their comb cut out. And defensive behaviour in African bees has been shown in published work to vary with time of day and with season, so the same colony is not equally dangerous at all hours. Note that the studies which measured this gave conclusions rather than numbers that could be retrieved for this course, so treat the evening rule as sourced local practice, not as a measured safety threshold. Never work a hot, still, thundery afternoon in a dearth.

How often should you harvest in a year? There is no national answer. A survey in the Gedeo zone of southern Ethiopia found 53 percent of beekeepers harvested once a year, 44.4 percent twice, and 2.2 percent three times. In Kenya, Transmara beekeepers took three harvests a year at about 10 kg a hive, while Kirinyaga beekeepers took 7.5 kg per harvest, twice, for about 15 kg a year. Both are correct for their own place, because both are following their own flowering.

That is why your flowering calendar matters more than any printed schedule. In one Ethiopian zone alone, the major honey season was February to March for most respondents in the mid-altitude areas, but October to December in a highland district of the same zone. Two districts, one zone, opposite seasons. Any course that prints harvest in month X is teaching a falsehood somewhere.

So build the decision from three checks, in this order.

1. Is the flow ending? Watch the flowering you recorded, and watch the traffic at the entrance falling off.
2. Are the combs three quarters or more capped? Open with that single question and get out.
3. Will the colony still have sealed stores after I take these bars? If not, take fewer bars or none.

One warning that belongs here. Never harvest a colony that has little sealed honey, however tempting the bars look and however much you need the money this week. A colony you strip in a dearth is a colony you do not have next season, and a hive with no bees earns nothing at all.

A bee colony does not arrange its nest at random. It builds the same pattern every time, and once you know that pattern you can walk to the honey without ever disturbing the brood.

The layout is this. Brood sits in the centre of the nest, where it is warmest. Around the brood, the bees pack a rim of pollen, which they call bee bread and which is the colony's protein store. Above and outside the pollen sits the honey. Brood in the middle, pollen around it, honey on the outside and on top.

That single fact is what makes clean harvesting possible. In a top-bar hive, work from the ends of the hive inwards. The outer bars are honey. As you move towards the centre you will reach pollen, and then brood, and that is where you stop. You do not need to open the brood nest at all to take a crop.

Now the rules for what goes into the bucket.

1. Take only fully or mostly capped honey comb. Three quarters or more sealed, as in the last lesson.
2. Never cut comb containing brood, eggs or larvae. Not a corner of it, not a small patch you think will not matter.
3. Never take pollen comb. That is the colony's protein and it belongs to the bees, and pollen in honey lowers your quality.
4. Return the brood nest intact. Put the brood bars back the way you found them, in the same order and the same direction.

Why is brood in the bucket such a serious matter? Four reasons, and each one costs you money.

First, dead bees and larvae are protein, and protein in honey feeds spoilage. Second, larvae are wet, so brood raises the moisture of your crop and moisture is the thing that ferments it. Third, crushed brood turns the honey dark and gives it a taste and a smell buyers will notice immediately. Fourth, and worst, you have destroyed the colony's next generation. A colony you take brood from is set back for weeks and is far more likely to abscond.

There is a measurable version of all this, and it is the reason the standard exists. The international Codex standard for honey sets water-insoluble solids at not more than 0.1 grams per 100 grams for standard honey. Water-insoluble solids means the wax, the bee parts, the pollen clumps, the grit and the ash that is not honey. Brood, pollen and debris go straight into that number. A buyer with a laboratory does not need to look inside your bucket to know how you harvested.

This is the heart of what the sources call the crude honey problem, and it is the central quality lesson of African beekeeping. Kenyan yield figures are repeatedly given as crude honey: 30 to 40 kg a hive in Kakamega, 33 kg from a single hive in Nandi Hills in April plus 15 kg more in June. Crude honey is comb, honey, brood, pollen and debris cut out and weighed together. It looks like a huge crop. It sells for a fraction of what the same crop earns strained, dried to specification and packed. The gap between crude honey and clean honey is where nearly all the lost value in African beekeeping sits, and the intervention is not more hives. It is selective harvesting and processing.

Hive type decides how much choice you have.

• Fixed-comb hives, meaning log, bark, gourd, clay pot or basket, do not let you select. The comb is attached to the walls and is cut out whole, brood and all. This is why fixed-comb hives yield crude honey and why the colony is usually set back or lost.
• Top-bar hives, Kenyan or Tanzanian, let you lift one bar at a time and cut only the capped honey off the bar. This is the cheapest route to clean honey that exists.
• Frame hives let you take whole supers of honey comb from above the brood nest, uncap and spin them, and give the comb back intact.

One practical note for the top-bar beekeeper. Cut the comb off the bar with a clean knife, leaving a narrow strip of comb attached along the bar. The bees use that strip as a guide and rebuild straight along the same line. Give the empty bar straight back to the colony.

And one honest warning. In a Tanzanian-pattern straight-sided hive the combs are attached to the walls and must be cut free with a knife at every inspection. That is slower and it is why sloping sides exist.

The moment honey leaves the hive it is food. Not a farm product, not a raw material. Food, sold to people who will eat it. Everything in this lesson follows from that one change of status.

Start with containers, because this is the single commonest honey contamination event in smallholder systems anywhere. Use clean, food-grade containers only. Never a container that has held fuel, pesticide, paint, soap, engine oil or any chemical. A jerrycan that once held diesel will taint honey permanently, and no washing will remove it. If you cannot say with certainty what a container previously held, do not put honey in it.

Also choose the right material for honey itself. Honey is acidic. The Codex standard permits free acidity of up to 50 milliequivalents of acid per 1,000 grams, and that is normal honey. That acid attacks metal. Never store or carry honey in galvanised, uncoated iron, or copper containers, because the honey will dissolve the metal into itself and you will be selling contaminated food. Stainless steel, food-grade plastic and glass only.

Next, cover everything. Honey is hygroscopic, which means it pulls water out of humid air. An open bucket standing in a coastal store or during the rains gains moisture every hour, and every point of moisture gained pushes your crop closer to fermenting. So the rule is: cover the bucket the moment you have filled it and keep it covered until you process it. Not a cloth. A lid.

Smoke next, because this is where careful beekeepers lose their crop without noticing. Smoke is a control on the bees, not a tool for handling comb. Kenyan practice smokes the entrance of the hive with about 8 to 10 puffs and then waits before opening. Smoke the entrance and smoke the bees off the comb. Do not smoke the comb you are about to cut, and do not let a smoking smoker sit beside an open bucket. Smoke taint in honey is permanent, it is obvious to a buyer, and there is no way to remove it once it is in.

Water is the other invisible ruiner. Do not harvest in the rain, and do not harvest just after rain onto wet comb. Water on the outside of a comb goes straight into the honey when you crush or cut it. Wet hands, a rinsed bucket that was not dried, a damp cloth over the top, all do the same thing.

Then the ordinary rules, which are ordinary but which are broken constantly.

• Clean hands, washed and dried, before you touch comb.
• A clean knife, kept in a clean container between hives, not stuck in the ground.
• No soil, no grass, no ash, no smoker fuel in the bucket.
• Do not set combs down on the ground, on a hive roof or on a sack. Cut straight into the covered bucket.
• Do not smoke tobacco, eat or spit while harvesting.
• If anyone in the harvest team has an open wound, a stomach illness or a skin infection, they do not handle honey that day.
• Transport covered and cool, and process the crop as soon as you can.

The last point deserves emphasis. Harvested comb standing around in a warm store is exactly where the worst small hive beetle slime-outs happen, and small hive beetle is a native African insect whose larvae ferment stored honey. Process promptly.

Now the honest limits of this lesson. The international framework for food hygiene is Codex CXC 1-1969, the General Principles of Food Hygiene, and its honey-specific application could not be obtained for this course. So the rules above are drawn from the sourced beekeeping practice and from general food hygiene, and they are principles rather than a certified protocol.

More importantly, the rules that actually bind you are national. Food-handler health requirements, whether a honey processing room must be registered, what materials are permitted for food containers, and what records you must keep are all set by your own country and differ widely. Ask your national food safety or standards authority. In Kenya that is KEBS, in South Africa SABS and the NRCS, in Nigeria SON, in Ethiopia ESA, and you should verify the current name and remit for your own country rather than trusting a list printed in a course. Get the requirement in writing before you sell into any formal market.

One last thought that turns all of this from a chore into money. Every rule in this lesson costs you almost nothing. A clean bucket and a lid cost less than a single kilogram of honey. The difference in what you are paid can be several times that.

If you remember one number from this whole course, make it this one. The Codex Alimentarius standard for honey, CXS 12-1981, sets moisture at not more than 20 percent for general honeys. Honey above that is not honey by the standard.

But do not aim at 20. Kenyan extension advises a working target of less than 19 percent water, and that is the figure to teach yourself. Here is why the extra point matters. Twenty percent is the ceiling, and a crop that arrives at the ceiling has no margin at all. Honey absorbs moisture from humid air. Honey packed at exactly 20 percent and stored in an open bucket in a humid coastal store will be over the limit within weeks, and it will be over the limit in the buyer's laboratory even though it passed in yours. Work to under 19 and you have a margin for the store, the transport and the shelf.

What actually goes wrong when moisture is high? Yeasts. Honey is a sugar solution so concentrated that most organisms cannot live in it, which is why it keeps for years. Add water and that protection weakens. Osmophilic yeasts, which tolerate high sugar, begin to work, and they convert sugars into acid, alcohol and gas. The honey froths, smells sour or winey, pushes the lid off the container and is no longer saleable as honey.

The standard catches this from the other end too. Codex sets free acidity at not more than 50 milliequivalents of acid per 1,000 grams. Acidity above that means fermentation has already happened. So remember the pairing: high moisture plus high free acidity is fermentation. That is one of two diagnostic pairs you should carry in your head. The other, low diastase plus high HMF, is heat damage, and it belongs to processing rather than harvest.

Be honest about one thing this course cannot give you. The exact moisture level at which a given honey ferments, and how that relates to the yeast count in it, comes from a body of honey science that could not be obtained for this material. So no fermentation threshold is printed here. What you should carry instead is this: the Codex ceiling is 20 percent, the working target is under 19 percent, and fermentation risk rises steeply as moisture rises. Do not go hunting for a magic number below which you are safe.

Now, how do you control moisture? Four practical steps and one measurement.

1. Harvest only capped comb. This is about ninety percent of the answer. The bees dried the honey for you and sealed it when it was ready. Everything else on this list is damage limitation for what you did at step one.
2. Cover honey at all times. Open containers gain moisture from the air.
3. Store and process in the driest room you have, not the coolest damp one. Beekeepers instinctively pick the cool store, and in a humid climate that is often the wrong choice.
4. Do not harvest in the rain or onto wet comb.

And the measurement: buy or borrow a honey refractometer. It is a small handheld instrument. You place a drop of honey on the glass, hold it to the light, and read the moisture percentage off a scale. It takes ten seconds.

This is the highest-value single piece of equipment a small beekeeper or a beekeeping group can own, and here is the reason stated plainly: without a refractometer you are guessing, and the buyer is not. A serious buyer will test what you deliver. If your honey fails at their bench you may lose the sale, the price, or the relationship. If you have tested it at your own bench you know before you load the vehicle, and you can decide what to do about it.

A refractometer is also often too expensive for one smallholder and entirely affordable for a group of ten. This is one of the concrete reasons cooperative membership pays.

What if your honey is already over? You can dry honey with warm air and dehumidification, and it is done commercially. But heat is not free. Warming honey destroys the enzyme diastase and creates HMF, and both are tested against the standard. No sourced protocol for drying over-moist honey, with a safe temperature, airflow and duration, could be obtained for this course, so none is printed here. Do not improvise one over a fire. Find a processor or a cooperative with proper equipment, or sell that batch for a use where it does not matter, and fix the real problem, which was harvesting uncapped comb.

One last point about margin. Moisture is the one parameter you control almost entirely at harvest, with a decision that costs nothing: leave the uncapped bars alone.

Most of the value lost after a good harvest is lost in the few hours between cutting the comb and getting it under a lid in a clean store. Nobody teaches this part, and it is where careful beekeepers are quietly robbed.

Start at the hive. Cut straight into a covered food-grade bucket. Not onto a sack, not onto the hive roof, not into an open basin that will be carried across the apiary. Each time you set comb down you add dust, grass, ash and bees, and each of those goes into the water-insoluble solids that the standard measures at not more than 0.1 grams per 100 grams.

Keep the lid on between combs. Open the bucket, drop the comb in, close it. In a humid evening the difference between an open bucket and a closed one over a two-hour harvest is real moisture, and moisture is the thing that ferments your crop.

Keep the bucket away from the bees you are working. An open container of honey in an apiary at dusk during a dearth will start a robbing frenzy, and robbing turns a calm apiary into a dangerous one very quickly. With African bees that is a safety matter, not an inconvenience. Carry filled buckets out of the apiary and into the vehicle or the store as you go, rather than stacking them beside you.

Separate your crop as you cut, because it costs nothing at the time and is impossible later.

• Fully capped, clean, light comb goes in one bucket. This is your best honey, and it is also the comb worth considering for cut comb sale, which needs no extractor, no straining and no settling tank, and often earns the highest price per kilogram of any form of honey. It is badly underused in Africa.
• Partly capped or slightly darker comb goes in a second bucket. Process it separately and sell it separately.
• Any comb that got dirty, dropped, or has a patch of pollen goes in a third. Use it for your own household, or for mead or for cooking, but do not let it into the batch you are selling on quality.

One bucket of poor comb tipped into good honey drags the whole batch down to its level. Grading at the hive is the cheapest grading you will ever do.

Now transport. Covered and cool. Cover the load against sun and dust. Honey left in a closed vehicle in the sun gets hot, and heat is what destroys diastase and creates HMF, the two figures that tell a buyer's laboratory you mishandled the crop. Never carry honey in the same load as fuel, pesticide, fertiliser, soap or paint, even sealed, because taint travels.

Then the rule that matters most: process promptly. Harvested comb standing around is the single best habitat you can offer to the two pests that will take it from you.

Small hive beetle is a native African insect. Its larvae feed in stored honey and cause fermentation and a slimy, foul mess, a slime-out, and the worst slime-outs happen in supers and buckets of harvested comb left standing rather than in living colonies. Wax moth is the pest African beekeepers actually lose most equipment to, and its larvae tunnel through comb, leaving silk and webbing. Wax moth develops fastest at 29 to 33 degrees Celsius, which is ordinary African ambient temperature, so it works on your stored comb all year round rather than seasonally as in Europe. Freezing comb at minus 7 to minus 15 degrees for 2 to 4.5 hours interrupts wax moth development, but most African smallholders have no freezer, so treat that as a technique for someone with cold storage and not as your answer.

Your real answer is speed. Cut today, crush and strain today or tomorrow, and get the honey into sealed containers and the wax into a bag for rendering. Do not store empty or harvested comb. If you must hold comb overnight, hold it sealed, off the ground, in the coolest and driest room you have, and deal with it first thing.

Finally the containers your honey will actually live in. Food-grade, airtight, and opaque. Airtight against moisture uptake, because honey pulls water from the air. Opaque and cool against colour darkening and HMF, which rise with storage temperature and time. Stainless steel, food-grade plastic or glass, never galvanised, uncoated iron or copper, because honey is acidic and will dissolve metal into itself.

Label every container as you fill it: hive or apiary, date, and whether it is capped-comb honey or mixed. That label is what lets you trace a problem back to a hive later, and it is what a serious buyer expects.

This is the lesson most harvesting courses skip, and it is the one that decides whether you have an apiary next year or a row of empty boxes.

Start with the honest position. No sourced figure exists for the minimum amount of honey to leave a colony going into an African dearth. This course will not invent one, because a wrong number here starves colonies, and the beekeeper following it would never know why. What you get instead is a principle, a method of measurement, and one rule you can apply immediately.

The principle: leave the colony enough sealed honey to survive the dearth ahead of it.

The rule: never harvest a colony that has little sealed honey, however tempting the bars look. If you open a hive and find one or two capped bars and nothing else, close it and walk away. Take nothing. That colony is already living close to the edge.

Now the method, and this is the part that makes you a better beekeeper than a printed number ever would.

Heft the hive. Stand at one end, take hold of the hive body, and lift it just enough to feel the weight, then let it down. Do that at harvest, and write down what you felt. Heavy, medium, light. Better still, use a spring balance and record a number. Then heft the same hive once a month through the dearth and record again. After one dearth you know how much weight your colonies lose in your climate over your dry months. After two dearths you know it well. That figure, measured on your own bees on your own site, is worth more than any published average from another country.

Why is this so serious in Africa specifically? Because of what happens when a colony runs short. A European colony that runs low on stores in a bad winter usually starves in place, and the beekeeper finds dead bees on the comb. An African colony that runs low will often abscond. Absconding means the whole colony abandons the nest, brood and all, and leaves. It is not swarming. Swarming splits a colony in two and the parent colony continues, so you lose half the bees. Absconding leaves you with an empty box, and you lose everything.

Dearth is the first trigger on the list. A colony with no forage and no stores has no reason to stay, and it will go. So over-harvesting does not merely reduce a colony, it removes it.

Do the arithmetic on what over-harvesting really costs. Suppose you take an extra 3 kg from a hive you should have left alone, and that colony absconds. Next season that hive produces nothing, because it is empty, and you must wait for a swarm to occupy it. Against Kenyan top-bar figures of roughly 15 to 18 kg a year, you traded 3 kg now for a whole year's crop, plus the risk that the box stands empty for a second season. Hives set out are occupied at somewhere between 30 and 75 percent in the sourced Kenyan and Ethiopian surveys, so an empty box is not automatically refilled.

There are three ways to reduce the risk that you take too much.

1. Harvest at the end of the flow, not into the dearth. The colony has just finished collecting, so what you take is genuinely surplus. The same kilograms taken two months later are food.
2. Take fewer bars from a weak colony and more from a strong one. Harvest by colony, not by rule. A strong hive with ten capped bars can give more than a small one with four.
3. Count what you are leaving, not just what you are taking. Before you close up, write on the record card how many capped bars remain. That number, next to what happened to that colony over the dearth, is your evidence for next year.

If a colony does run short during the dearth, feeding is the emergency answer. Kenyan practice uses sugar syrup mixed two parts sugar to one part water, and stimulative feeding is started 6 to 8 weeks before flowering because it takes about six weeks from egg to adult foraging bee. Two hard rules go with it. Never feed with honey supers on, and never feed in the run-up to harvest, because the syrup ends up in your crop. Codex requires that nothing be added to honey, and sucrose above 5 grams per 100 grams is one of the tests that catches exactly this. Feeding a starving colony is good beekeeping. Feeding a colony you are about to harvest is adulteration.

The honest summary is this: you are not harvesting honey, you are harvesting surplus. Learn to tell the difference and your apiary compounds year on year instead of resetting to zero.
