How Bees Make Honey: A Simple Explanation for New Beekeepers

If you have recently taken your first steps into beekeeping — perhaps after attending a local British Beekeepers Association (BBKA) taster day or joining your county beekeeping association — you will quickly discover that honey is far more than a sweet by-product of keeping bees. It is the result of thousands of hours of collective effort, extraordinary biological processes, and the seamless coordination of an entire colony. Understanding how bees make honey will not only deepen your appreciation for your hive, but it will also make you a more attentive, effective beekeeper.

This guide walks you through the entire honey-making process from flower to jar, with specific reference to conditions, plants, and regulations relevant to beekeeping in the United Kingdom.

Why Bees Make Honey in the First Place

Before looking at the mechanics of honey production, it helps to understand why bees make it at all. Honey is not a gift to humans — it is a survival food store. In the UK, winters are long and cold, and flowering plants stop producing nectar from around October through to March. A healthy colony of western honeybees (Apis mellifera) — the species kept by the vast majority of British beekeepers — needs roughly 20 to 30 kilograms of stored honey to survive the winter months without starving.

This drive to stockpile food is what motivates every aspect of foraging behaviour and in-hive processing during the summer. As a beekeeper, your role is to manage the colony so that bees can do this naturally whilst you can take a sustainable surplus for yourself without leaving the bees short.

Step One: Foraging for Nectar

The Role of the Forager Bee

Nectar collection is the job of forager bees — worker bees that are typically between 21 and 40 days old. Younger workers perform in-hive tasks such as nursing larvae, building comb, and processing nectar. As they age, their in-hive glands reduce in activity and they transition to flying out of the hive to find food sources.

A forager bee can travel up to five kilometres from the hive, though most efficient foraging happens within a two-kilometre radius. In practical terms, this means your bees are visiting gardens, hedgerows, allotments, orchards, and farmland across a wide area. This is one reason why urban and suburban beekeeping has grown so rapidly in British cities like Bristol, Edinburgh, Manchester, and London — urban gardens often provide a more diverse and reliable nectar source than monoculture farmland.

What Is Nectar?

Nectar is a sugary liquid secreted by flowering plants from structures called nectaries, usually found at the base of flower petals. It consists largely of water (up to 80%) combined with a mixture of sucrose, fructose, and glucose. Different plant species produce nectar with varying sugar concentrations and compositions, which affects the flavour and characteristics of the resulting honey.

In the UK, some of the most important nectar sources include:

Oil seed rape (Brassica napus) — a dominant spring crop across much of England and Scotland, producing large amounts of nectar but yielding a honey that granulates very quickly in the comb.
White clover (Trifolium repens) — historically the backbone of British honey production, found in meadows, gardens, and lawns throughout the country.
Heather (Calluna vulgaris) — the source of Scotland’s prized ling heather honey, a thixotropic honey with a distinctive flavour harvested in late summer on moorland.
Lime trees (Tilia species) — found lining avenues in many British towns and parks, providing a powerful nectar flow in July.
Borage, phacelia, and wildflower mixes — increasingly planted by farmers under agri-environment schemes such as those funded through the UK’s Countryside Stewardship programme.
Fruit tree blossom — apple, pear, and cherry orchards across Kent, Worcestershire, and the West Country provide important early-season forage.

How the Bee Collects Nectar

When a forager bee lands on a flower, it uses its proboscis — a long, tube-like tongue — to draw up the nectar. This nectar is stored not in the bee’s stomach but in a specialised organ called the honey stomach or crop, which sits just ahead of the digestive stomach. A valve between the two prevents the nectar from being digested. Once full, the honey stomach can hold around 40 milligrams of nectar — roughly 80% of the bee’s own body weight.

During collection, the bee also picks up pollen on the fine hairs covering its body. Much of this pollen is transferred between flowers as the bee forages, making honeybees one of the most important pollinators of both wild plants and agricultural crops in the UK. The economic value of honeybee and bumblebee pollination to British agriculture is estimated at over £600 million per year.

Step Two: Returning to the Hive and Transferring Nectar

The Waggle Dance

Before returning to the hive, foragers that have found a particularly good nectar source will communicate its location to their hive-mates using the famous waggle dance — a figure-of-eight movement performed on the surface of the comb. The angle of the dance relative to vertical indicates the direction of the food source relative to the sun, and the duration of the waggle run indicates distance. This extraordinary navigational communication system, first decoded by Austrian zoologist Karl von Frisch in the 1940s, allows a colony to rapidly recruit foragers to productive patches of flowers.

Handing Off the Nectar

On returning to the hive, the forager passes her load of nectar to a house bee through a process called trophallaxis — mouth-to-mouth transfer. During this transfer, which can be passed through a chain of two or three bees, the first crucial step in nectar processing begins. The bees’ salivary glands introduce an enzyme called invertase, which starts breaking down sucrose molecules into simpler glucose and fructose sugars.

This enzymatic conversion is one of the key differences between nectar and honey. Raw nectar is primarily sucrose; finished honey is primarily glucose and fructose. The invertase enzyme continues working throughout the curing process.

Step Three: Evaporating Water from the Nectar

Why Water Content Matters

Fresh nectar contains far too much water to be stored safely. At 60–80% water content, nectar would ferment rapidly due to wild yeasts naturally present on flowers and in the hive environment. Honey is shelf-stable precisely because its water content is reduced to below 20% — typically between 17% and 19% in properly ripened British honey. At this concentration, the high sugar content creates an osmotic environment that inhibits microbial growth.

Achieving this low water content in the damp British climate is no small feat, and it is one reason why beekeepers must be patient about harvesting. Honey taken too early, before it is fully ripened, will ferment in the jar.

How Bees Evaporate the Nectar

House bees actively work to drive off moisture through several methods:

Spreading the nectar thinly across comb cells — this increases the surface area exposed to the warm hive atmosphere.
Repeatedly regurgitating and re-ingesting droplets — bees will hang droplets of nectar from their proboscis, exposing them to the warm air inside the hive before drawing them back in. This process is repeated many times over several hours or days.
Fanning behaviour — groups of worker bees position themselves at the hive entrance and across the combs, beating their wings rapidly to create airflow through the hive. This ventilation carries moisture-laden air out of the hive and draws in drier air from outside.

Inside the hive, the temperature is maintained at a remarkable 35°C throughout the active season — ideal conditions for enzymatic activity and moisture evaporation. As a new beekeeper inspecting your hive on a warm summer afternoon, you may notice bees fanning actively at the entrance: this is a healthy sign of nectar processing underway.

The Role of UK Climate

The British climate presents particular challenges for honey curing. Prolonged wet summers — such as those experienced across much of England and Wales in 2012 and 2023 — mean higher ambient humidity, making it harder for bees to reduce moisture levels in stored nectar. In such years, beekeepers in the UK may find honey with a higher-than-ideal water content even when capped cells appear ready. Using a refractometer to check the water content of your honey before extraction is strongly advised and is considered best practice by the BBKA.

Step Four: Capping the Honey

Once the nectar has been processed to a water content below approximately 20%, the bees seal each cell with a thin layer of beeswax. This wax capping is the signal that the honey inside is ripe and ready. The cappings on ripe honey are typically slightly domed and have a dry, white or pale yellow appearance. Cappings that are wet-looking or sunken may indicate honey that has not fully ripened.

As a beekeeper, you should only extract frames where at least 80% of the cells are capped. Many experienced British beekeepers advise waiting until a frame is fully capped before removing it for extraction, particularly if you are producing honey for sale under the Honey (England) Regulations 2015 (and equivalent devolved legislation in Scotland, Wales, and Northern Ireland), which set legal standards for water content and composition.
