Honey

• 1. Introduction

  ›

  Honey does not spoil when it is stored properly, and archaeologists have found samples that stayed edible after millennia. Cave paintings in Cuevas de la Araña, in Spain, show people foraging for honey at least 8,000 years ago. Long before Apis mellifera reached the Americas, Maya communities were already practicing large-scale meliponiculture with stingless bees, well before European contact. Bees do not make honey to please humans. They make it to survive winters and lean seasons, turning watery nectar or the honeydew of aphids into a dense reserve. That reserve is stored inside a wax honeycomb built from hundreds or thousands of hexagonal cells. How does a forager bee turn a runny liquid into something that can sit in a jar for centuries without rotting? Why do modern beekeepers worry about corn syrup slipping into their product, when adulteration has been documented since ancient times? And why did one ancient culture bury honey with the dead for their journey into the afterlife, while another religion forbids eating it altogether? The answers start inside the bee itself, long before the honey reaches a human hand.

• 2. How Bees Make Honey

  ›

  A foraging bee begins the process by sucking up sugar-rich nectar or honeydew through its proboscis. The liquid goes into a separate honey stomach rather than the bee's food stomach. Nectar leaving the flower usually holds 70 to 80% water, far runnier than finished honey, which settles near 18%. The stomach holds about 40 milligrams of liquid, roughly half the bee's own weight, and takes over an hour of continuous work to fill. Salivary enzymes from the bee's hypopharyngeal gland start breaking sucrose and other sugars into simpler glucose and fructose while the nectar sits in this crop. Back at the hive, the forager regurgitates the nectar to a hive bee. That bee repeats the process, forming bubbles between its mandibles to speed digestion and evaporation. Bees organize into honey-processing groups that pass the liquid in relay, a cycle that can take up to 20 minutes before it reaches storage quality. The result goes into uncapped honeycomb cells still holding as much as 70% water, moist enough for yeast spores to multiply if left unchecked. To stop that, bees rely on an ability rare among insects: generating substantial body heat. This keeps the honey-storage areas of the hive around 35 degrees Celsius. Wing beats drive air across the wet honey, pulling out water and heat. The mixture reaches a final water content between 15.5 and 18 percent, too concentrated for fermentation to continue. Once finished, the bees seal each cell with a wax cap, blocking contamination and further evaporation. Honey bees are not alone in this trick. Bumblebees and stingless bees also produce honey. Wasps such as Brachygastra lecheguana and Brachygastra mellifica, found in South and Central America, feed on nectar to make their own. Another wasp, Polistes versicolor, alternates between feeding on protein-rich pollen and feeding on the far denser energy of honey through its life cycle.

• 3. From Wild Swarm To Working Hive

  ›

  A colony swarms when the old queen lays eggs that will grow into new queens, then leads as much as half the hive to search for a new home. Until scouts find a suitable site, the swarm often clusters on a tree branch near the old hive, unusually calm and easy for a person to move. Placed inside a manufactured shelter such as a Langstroth hive, the swarm will readily settle in and start a new colony. Because any hive can still abandon its keeper and re-establish itself in the wild, beekeepers describe their bees as semi-domesticated rather than fully domesticated. Much of a modern beekeeper's work goes into stopping a hive from swarming at all, usually by stacking empty boxes called honey supers on top of the colony. This gives the bees room to build more honeycomb where they already live instead of splitting off. A hive produces about 65 pounds of honey a year on average. A wild nest can be tracked down by following a honeyguide bird to its location. To harvest safely, beekeepers use a smoker, which triggers a feeding instinct in the bees and masks the pheromones they use to communicate danger. Once calm, the bees' honeycomb is removed. The honey is separated by crushing it or spinning it out in a honey extractor, then filtered to remove wax and debris. Before removable frames were invented, harvesters often destroyed the whole colony to take its honey and started fresh the following spring. Since then, most beekeepers instead leave enough stores behind, or feed the colony a substitute like sugar water or a candyboard, so it survives the winter.

• 4. Why Honey Doesn't Spoil, Or Get Faked

  ›

  Despite a popular legend, no edible honey has ever actually been found inside an Egyptian tomb. Every reported case has turned out to be a different substance or just a chemical trace. Real preservation instead depends on keeping moisture out, since honey's hydrophilic nature pulls water from humid air. Enough moisture can eventually dilute the honey until fermentation starts. Much of its resistance to spoiling traces back to an enzyme in a bee's stomach called glucose oxidase. It mixes with expelled nectar to create gluconic acid and hydrogen peroxide, both of which suppress bacterial growth. That same value has made honey a frequent target for fraud since ancient times. Historical sources describe pure honey blended with maple, birch, or sorghum syrup and sold as genuine. Sellers sometimes mixed flour or other fillers into crystallized honey, a trick that stayed hidden until the honey was heated back into liquid. Today the most common adulterant is clear, nearly flavorless corn syrup, which can be very difficult to distinguish from the genuine product. The Codex Alimentarius, a United Nations food standard, states that anything labeled honey or pure honey must not be adulterated, though labeling rules still vary by country. The National Honey Board in the United States has called authenticity one of the industry's biggest challenges, noting that no single test can catch every form of fraud. One method, isotope ratio mass spectrometry, compares carbon signatures in the honey. Corn and cane sugar come from C4 plants, while the flora bees use are mostly C3 plants. This difference lets the method catch adulteration levels as low as seven percent. In 2023, world honey production reached 1.9 million tonnes, led by China with 24 percent of the total, followed by Turkey, Ethiopia, and Iran.

• 5. The Strange Physics Of Honey

  ›

  Honey's density ranges from 1.38 to 1.45 kilograms per liter at 20 degrees Celsius, denser than water because it carries so much dissolved sugar. That oversaturation makes honey a supercooled liquid at room temperature, causing dissolved glucose to slowly precipitate into solid crystals. How fast that crystallization happens depends mainly on the ratio of fructose to glucose in a given honey. Brassica honey, high in glucose, turns solid almost as soon as it is harvested. Chestnut and tupelo honey, low in glucose, barely crystallize at all. Honey from heather or mānuka behaves unlike most other liquids. Left alone it turns gel-like, but stirring makes it flow again, a property called thixotropy. Color varies just as widely. Honey is typically pale yellow to dark brown, but bees foraging on Kudzu flowers produce honey that ranges from red to purple. Beekeepers also classify honey by its floral source, and monofloral honey comes mainly from one type of flower, such as clover or orange blossom. Mānuka honey, made from Leptospermum scoparium in New Zealand, is darker and earthier than lighter honeys like clover. Honeydew honey skips flowers entirely, made from tree secretions such as pine, fir, chestnut, and oak, or from the honeydew of aphids. This gives it a stronger, less sweet flavor than nectar-based honey. In Greece, pine honey alone makes up 60 to 65% of national honey production. Nutritionally, honey overall is about 17% water and 82% carbohydrate, supplying roughly 300 calories per 100 grams. Fructose and glucose make up the great majority of its sugars.

• 6. Medicine, Myth, And Culture

  ›

  The oldest known honey remains were found in Georgia, on the route of the Baku-Tbilisi-Ceyhan pipeline. They were preserved on the inner walls of clay vessels in an ancient tomb dated between 4,700 and 5,500 years old. Ancient Georgians buried linden, berry, and meadow-flower honey alongside the dead to sustain them on their journey into the afterlife. Ancient Egypt left the first written records of beekeeping, using honey to sweeten cakes and biscuits and as a base for ointments described in hieroglyphs. In Athens, honey production was widespread enough by 594 BCE that the lawmaker Solon required beehives to sit at least 300 feet apart. The Hebrew Bible calls Canaan the land of milk and honey 16 times. The Quran devotes an entire chapter, called an-Nahl, to bees, describing a drink of varying colors that offers healing. Jainism, by contrast, counts honey among four absolute prohibitions, since harvesting it kills bees and its thick texture is believed to constantly breed microscopic life. At Rosh Hashanah, Jewish tradition dips apple slices in honey to welcome a sweet new year. Honey's antibacterial power was first demonstrated scientifically by the Dutch scientist Bernardus Adrianus van Ketel in 1892. Modern medical-grade honey products are now approved by the US Food and Drug Administration for treating minor wounds and burns. The World Health Organization recommends honey for coughs and sore throats, even in children, but infants under one should never be given it, since Clostridium botulinum spores in honey can cause infant botulism. Reported rates vary sharply by country: the UK recorded only six cases between 1976 and 2006, while the United States sees about 1.9 cases per 100,000 live births, with 47.2% of them occurring in California.
