Tree heath honey
Strong, malty and slightly bitter, with a burnt-caramel depth and a woody finish — assertive in a way that divides opinion sharply.

HoneyHQ reference sheet — honeyhq.app/honey/tree-heath-honey, record reviewed 2026-08-02. Values describe the honey type, not any one jar; sources are listed at the end.
A dark, malty Iberian honey from tree heath, one of the most distinctive honeys of Spain and Portugal and quite different from the ling heather honey of northern Europe despite sharing a common name. It flowers in early spring on acid hillsides, produces a honey the colour of strong tea, and carries a characteristic bitter-caramel finish.

Laboratory reference; taste described by HoneyHQ
Published laboratory values exist for this honey type, but no panel description was published with them. The taste words are HoneyHQ's synthesis of producer and literature descriptions; the laboratory values do not prove them.

Pfund grades, palest to darkest. Outlined: where this honey usually falls. Swatches are illustrations; real colour depends on depth, container and light. Deep reddish-brown, the colour of strong tea, sometimes near-black in Portuguese production.
On setting: Sets to a dark opaque brown.
- Texture
- Thick but pourable; Soft set; Crystallised
- Crystallisation
- Moderate, step 3 of 5, from very slow to very fast
Moderate — granulates over a few months; sets with a medium crystal.
Sets over a few months to a medium grain. It is thick in the jar even before granulation, which is characteristic of the Erica honeys generally.
Typical composition
- Moisture
- 15–19% (typically 17%)
- Fructose

- pH

What laboratories and tasting panels measured
From the summary table of the European reference description of Erica arborea (tree heath) honey. 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
- 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.
- 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.
- 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.
- 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.
- 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.
Summary values only. The source includes this type in its comparison table but had too little data to publish a full descriptive sheet, so no sample counts, limits or sensory description are given.

Where it comes from
- Floral source
- Erica arborea, tree heath, a tall heather of Mediterranean and Atlantic hillside scrub, with other Erica species contributing.
- Origins
- Portugal, northwestern and central Spain, and parts of Italy, Corsica and Sardinia.
- Origin pages
Resolved from both directions — origins this honey names, and origins that name it.
- Typical harvest
- March to June (northern hemisphere)
An early flow, well ahead of the northern European heather season.
A typical window for the honey type, HoneyHQ synthesis — not a calendar for any one place.
- The bees
- Worked in Iberia principally by the Iberian honey bee, a subspecies adapted to hot dry summers and mild winters, and one whose distinctiveness is diluted by imported queens in commercial areas.
- Usual processing
- Raw, Coarsely strained, Spun (centrifugally extracted), Pressed
Produced on acid hillside scrub that has little other agricultural value, which makes it economically important in poorer upland areas of Portugal and Spain.
What to do with it
Too assertive for a delicate use and excellent where that assertiveness is wanted — with cured meat, strong cheese or in a dark cake.

Where this honey sits in the catalogue
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
Heather honey has been produced on Iberian hillsides for as long as beekeeping has existed there, and it remains one of the few products of ground otherwise regarded as waste.
- Used in Portuguese domestic tradition for coughs and colds.
Traditional use records that people have done something, and for how long. It is not evidence that it works.
