Miel d'acacia / Akácméz

HoneyHQ reference sheet — honeyhq.app/honey/acacia-honey, record reviewed 2026-08-02. Values describe the honey type, not any one jar; sources are listed at the end.

The palest widely available honey and the one that stays liquid longest. Acacia honey does not come from an acacia at all: the source is Robinia pseudoacacia, the black locust or false acacia, a North American tree naturalised across central and southern Europe. It is water white to extra white, almost clear in the jar, and its flavour is deliberately unassertive — clean sugar, a little vanilla, a faint floral lift and nothing that lingers.

Checked against a trained tasting panel

A trained panel's published description of this honey type exists, and the scales on this page are compared with it below. Panels describe populations of honey from a stated region and period; a single jar can differ.

Pfund grades, palest to darkest. Outlined: where this honey usually falls. Swatches are illustrations; real colour depends on depth, container and light.

Almost colourless with a green-gold cast, pale enough to read newsprint through a jar. The palest honey in general commerce.

On setting: Rarely crystallises, but turns pale ivory and slightly cloudy if it eventually does.

Texture
Runny

Thin and fast-pouring, noticeably runnier than most honeys at the same temperature.

Crystallisation
Very slow, step 1 of 5, from very slow to very fast

Very slow — often still liquid after a year or more; sets with a fine crystal.

Acacia is the most fructose-dominant common honey, with a glucose-to-fructose ratio near 0.6 against roughly 1.0 for clover. Glucose is the sugar that comes out of solution first, and there is comparatively little of it here, so the honey can sit liquid for a year or more. This is a compositional fact, not a sign of processing — and it is exactly why acacia is the honey most often used as a base for adulteration with syrup, since a fake that stays liquid raises no suspicion.

Typical composition

Moisture
15–18% (typically 16.5%)
Fructose
41–48% (typically 44%)
Glucose
24–31% (typically 27%)
Glucose-to-fructose ratio
0.5–0.7 (typically 0.6)
pH
3.5–4.2 (typically 3.9)
Electrical conductivity
0.1–0.3 mS/cm (typically 0.17 mS/cm)

These are typical ranges assembled across published work, not measurements of a specific honey. Typical values across published compositional work on European Robinia honey. Every figure varies by season and region — these are the range a genuine acacia honey usually falls in, not a specification.

What laboratories and tasting panels measured

From the European reference description of Robinia (black locust, "acacia") honey: 715 authentic samples pooled by the International Honey Commission. These describe a population of honeys, not this or any particular jar — the standard deviations and sample counts are here so that no mean is mistaken for a specification.

What each measurement tells you
Pollen of the named plant
Share of the pollen that comes from the plant the honey is named after. Varies enormously by plant — chestnut over-represents its pollen, citrus and lavender under-represent theirs — which is why no single percentage defines 'monofloral'.
Colour
Depth of colour on the Pfund scale — 0 is water-white, above 114 is dark amber. Tracks minerals and phenolic compounds, and darkens with heat and age.
Electrical conductivity
How well a honey solution carries current, which rises with its mineral and acid content. The main official test separating honeydew and chestnut honeys (high) from most blossom honeys (low).
Specific rotation
The direction in which the sugars turn polarised light. Fructose turns it left, so blossom honeys read negative; honeydew honeys carry oligosaccharides that turn it right and read positive.
pH
Acidity as a logarithmic scale. Honey is always acidic; honeydew and chestnut honeys sit highest because their minerals buffer the acids.
Free acidity
The acid present as free acid, mostly gluconic acid made by the bee enzyme glucose oxidase. Rises with fermentation, which is why it has a legal ceiling.
Lactones
Acid held in lactone form — the reserve that free-acidity titration does not see. Added to free acidity to give total acidity.
Total acidity
Free acidity plus lactones.
Water
Moisture content. Decides whether a honey can ferment and how fast it pours; set by the nectar, the weather and how long the bees ripened it.
Diastase activity
Activity of the starch-digesting enzyme the bees add. Falls with heating and storage, so a low value in a honey that should be high suggests heat or age — but some honeys, citrus and acacia among them, are naturally low.
Invertase activity
Activity of the bee enzyme that splits sucrose into glucose and fructose. More heat-sensitive than diastase, and a sharper indicator of freshness and gentle handling.
Proline
The main free amino acid, mostly from the bees' own secretions. A low value is one signal of sugar-syrup dilution or of an unripe honey.
Fructose
The sweeter, more soluble of the two main sugars. Honeys rich in it stay liquid.
Glucose
The less soluble of the two main sugars and the one that crystallises. Honeys rich in it set quickly and finely.
Sucrose
Ordinary sugar, mostly split by the bees during ripening. A few honeys — lavender, acacia, citrus — keep more of it naturally, which is why their legal limits are higher.
Fructose + glucose
The two main sugars together. Lower in honeydew honeys, which carry more oligosaccharides — melezitose, erlose and others — made by the insects that produced the honeydew.
Fructose ÷ glucose
The single best predictor of whether a honey crystallises. Below about 1.1 it sets quickly; above about 1.3 it tends to stay liquid for a long time.
Glucose ÷ water
How much glucose there is for each part of water. Above about 2.1 the solution is supersaturated enough to crystallise fast; below about 1.7 it crystallises slowly or not at all.

Population: Authentic unifloral honeys produced in 21 countries of the European geographical area, analysed by 20 laboratories in 11 countries of the International Honey Commission working group formed in 1998; published 2004.

Electrical conductivity and specific rotation are expressed on honey dry matter; every other value on the honey as it is.

Diastase and invertase are given for fresh honeys only; both fall with age and heating.

The limits are the source's 95% confidence limits, replaced by the observed minimum or maximum wherever the limit would have fallen outside the data.

Protected versions and what they require

2 protected names sell this honey type under a registered specification. Each sets limits a jar must meet to carry the name — they describe that protected honey, not every acacia honey.

Slovenski med — PGI, acacia (black locust) type (Acacia)

The whole territory of the Republic of Slovenia.

To carry the name Slovenski med, a honey must:

  • be harvested within the defined area above;
  • show the plant's pollen share the specification sets, read by pollen analysis;
  • meet the 5 physico-chemical limits in the table;
  • be produced and handled under its 5 rules;
  • be certified under the scheme’s controls.

No single test checks all of these: pollen analysis, laboratory chemistry and a tasting panel each answer part, and the paperwork answers where the honey came from. This is a reading of the specification, not legal advice.

Where it comes from

Floral source
Robinia pseudoacacia. The naming confusion is old and permanent: true acacias (now mostly Vachellia and Senegalia) are a different genus on a different continent, and the honey they yield is nothing like this.
Origins
Hungary and Romania are the largest producers, with substantial volumes from Italy, Bulgaria, Serbia, Slovakia and China.
Origin pages

Resolved from both directions — origins this honey names, and origins that name it.

Typical harvest
May to June (northern hemisphere)

A short and famously unreliable flow. Robinia blooms for barely two weeks and a cold or wet spell during it can wipe out the crop for the year.

A typical window for the honey type, HoneyHQ synthesis — not a calendar for any one place.

The bees
Worked hard by honey bees when the weather allows, because the flow is intense while it lasts. The narrowness of the window is why acacia is one of the few honeys where beekeepers routinely move hives to catch it.
What counts as monofloral
Robinia pollen is under-represented relative to its nectar contribution, so a genuine acacia honey can show a low Robinia pollen percentage. Buyers and laboratories therefore lean on physical measures — very pale colour, high fructose share, low conductivity — as much as on pollen counts.
Usual processing
Spun (centrifugally extracted), Coarsely strained, Filtered

Almost always sold liquid and filtered, because pale clarity is the commercial point of it.

What to do with it

The default choice where honey should sweeten without announcing itself: in tea, over yoghurt, in a delicate dressing, or anywhere the honey flavour would compete. It is largely wasted in long baking, where the delicacy is destroyed by heat and any dark honey would do the same job for less money.

Pairings

  • Fresh goat cheeseClassic

    The honey is sweet without being aromatic, so it lifts the acidity of a young chèvre instead of arguing with it.

  • Green and white teaClassic

    Delicate teas are the easiest thing in the kitchen to bury under honey. Acacia is one of the few that sweetens a gyokuro or a silver needle without erasing it.

  • Ricotta and fresh figs

    Nothing here has a strong flavour; the honey's job is texture and sweetness only.

  • Pancakes and waffles

    Pours cold without warming, which no thick honey does. A practical rather than a gastronomic reason, and none the worse for it.

Pairing pages this honey appears on

Similar honeys and substitutes

Three different questions with different answers: a honey that tastes alike can behave differently in a recipe, and the same set texture says nothing about flavour. Each list is chosen from the recorded fields that matter to its question — and, where tasting panels or specifications described both honeys, the terms they share — and every suggestion says which, and what will be different. Compare it side by side or build a tasting flight.

History and traditional use

Robinia pseudoacacia was introduced to Europe from North America in the early seventeenth century and planted widely for timber, erosion control and — later and deliberately — for bee forage. Hungary's acacia industry is built on plantations established for that purpose, which makes acacia honey a modern European product from an American tree with an African-Australian name.

  • Given to children in central and eastern Europe as the mildest honey, for exactly the reason it is mild.
  • Used in Hungarian and Romanian pastry work where a darker honey would colour the crumb.

Traditional use records that people have done something, and for how long. It is not evidence that it works.
