Honey Harvesting: When and How

Idris Beaumont 20 May 2026 11 min read

Harvesting is the reward, and it is also where beginners lose most of their crop — either by taking honey that was not ripe, or by taking so much that the colony starves before spring.

How to tell honey is ripe

Ripe honey is capped honey. Bees remove moisture from nectar until it reaches roughly 18 per cent water content, then seal the cell with a thin wax lid. That capping is the beekeeper's signal, and it is a better indicator than any refractometer reading taken in a hurry.

Aim for at least 80 per cent of the frame capped before you take it.
Uncapped honey is typically 20–25 per cent water and will ferment in the jar.
Cappings should be pale and dry-looking. Wet, dark cappings suggest recent work.
In humid climates, be stricter. In arid climates, bees cap at a lower moisture content and you can be slightly more relaxed.

Never bottle uncapped honey

Honey above about 20 per cent moisture ferments. Fermented honey is not just a ruined jar — it can be a health risk. If in doubt, leave the frame on the hive another week.

How much to take

Take the surplus, leave the stores. The colony needs a substantial reserve to survive winter, and the amount depends entirely on your climate.

Climate	Stores to leave	Notes
Cold continental	20–25 kg per colony	Long winter, no forage for 5+ months
Temperate	15–20 kg per colony	Check by hefting the hive
Mild / Mediterranean	10–15 kg per colony	Some winter forage may be available
Tropical	5–10 kg per colony	Year-round forage; dearth periods matter more

If you are unsure, heft the back of the hive. A hive with adequate stores feels heavy and immovable; a light hive tips easily. A hive scale removes the guesswork entirely.

Clearing bees from the supers

You need the supers free of bees before they leave the apiary. There are four standard ways and they differ in how much disturbance they cause.

Bee escape: a one-way valve in the inner cover. Bees leave the super and cannot return. Gentle and effective, but takes 24 hours and works poorly in cold weather.
Fume board: a board with a repellent applied, placed on top. Fast — minutes — but the smell is strong and some beekeepers dislike it.
Brushing or shaking: frame by frame. Labour-intensive and agitating, but it is the only option when you need one frame immediately.
Blowing: a leaf blower used carefully. Fast for large operations; needs a controlled technique or you blow bees across the yard.

The easiest method

Fit a bee escape the evening before you plan to harvest. Come back the next morning and the supers are nearly empty of bees. It costs nothing but a day of patience.

Running the extraction

Extraction is a wet, sticky operation and it goes much better if you set it up before you start rather than improvising.

Set up the room

A warm, bee-proof room with a hard floor. Cover surfaces. Have everything within reach before you open the first super.

Uncap the frames

Cut the cappings off in one smooth stroke with a heated knife, or slice with a serrated knife if the honey is warm. Cut just below the capping — do not cut into the comb.

Spin the frames

Load the extractor symmetrically and spin slowly at first, then build up speed. Radial extractors drain both sides at once; tangential machines need frames turned halfway.

Drain and filter

Let the extractor stand for twenty minutes, then open the gate through a coarse filter and a finer one below it.

Settle before bottling

Leave the honey in a settling tank for 24 to 72 hours. Air bubbles rise and fine wax floats, and you draw clean honey from the bottom gate.

Uncap, spin, strain, settle. Each step has a reason, and skipping one shows up in the jar.

What to do with the cappings

Cappings are worth keeping. Rinse them in warm water to recover the honey, then melt the wax in a double boiler or a solar wax melter. You will get roughly 1 kilogram of cappings for every 10 kilograms of honey, and the wax is the cleanest you will ever have.

Never melt wax over a direct flame. Wax is flammable and overheated wax catches fire with very little warning.

After the harvest

Put the wet supers back on the hive for the bees to clean up — but only if there is no robbing pressure and no disease concern.
Never put wet supers back if there is any suspicion of foulbrood. That spreads disease across the apiary.
Treat for mites after harvest, once supers are off, if your treatment requires it.
Feed 2:1 syrup if the colony is light. This is the moment winter survival is decided.
Clean every piece of equipment with warm water and dry it thoroughly before storage.

The measure of a good harvest

You took only capped frames, the colony went into autumn heavy, and nothing fermented. The total weight matters far less than those three things.
