This is the Iberian profile in which bitterness stands out more strongly than sweetness. That reversal is the first thing many tasters notice.
Chestnut honey can have bitter notes, especially with a heather contribution, and heather honey can also show bitterness. In strawberry tree honey bitterness leads and sweetness remains in the background. It is a distinctive choice for people who enjoy a bitter finish.
Reading and tasting strawberry tree honey
This Spanish-language field guide compares botanical origin, tasting and laboratory findings. Use the profile together with the traceability of the lot.
Distinguish bitterness from the origin marker
- Record the bitterness and the secondary sweetness separately.
- Read the laboratory marker alongside pollen, origin and the sensory profile.
The botanical marker and the source of bitterness
The guide uses homogentisic acid, above 200 mg/kg, as one marker of strawberry tree origin. This is distinct from identifying the compound chiefly responsible for bitterness. A 2021 study using chemical separation and sensory testing identified unedone as the main contributor in its samples (DOI 10.3390/molecules26092765).
The guide also uses a marker in other profiles: methyl anthranilate in citrus blossom honey, perseitol in avocado honey and acetovanillone in lavandin honey. In strawberry tree honey the laboratory can use homogentisic acid to assess origin, while sensory tests point to unedone for bitterness. These observations answer different questions.
Colour
Amber to dark amber, sometimes darker with honeydew. The composition table gives a minimum of 70 mm Pfund, while the guide’s visual description gives 80. Both figures are worth knowing when reading this particular profile.

Aroma, taste and texture
Sensory profile
Our interpretation of the descriptions in the Guía de mieles monoflorales ibéricas. This is the entry in the guide where bitterness is rated above sweetness.
Aroma
Floral with earthy notes of forest floor, fallen leaves and mushrooms, reminiscent of heather. Honeydew can add malt notes. The overall impression is of damp autumn woodland.
Taste
The defining taste is bitter, with some saltiness and sweetness in the background. Its character is immediately apparent alongside a mild, predominantly sweet honey.
Crystallisation
It tends to crystallise quickly, sometimes unevenly, especially when moisture is high. As in avocado honey, a coarse or uneven set can occur. The guide often records moisture at or above 18.5% without specifying a separate maximum in this profile.
Higher moisture increases susceptibility to fermentation. Keep the jar tightly closed and check the batch if there are signs of fermentation. Our guide explains how moisture affects honey.
Interpreting the laboratory profile
| Parameter | Reference in the guide | How to interpret it |
|---|---|---|
| Colour | at least 70 mm Pfund | Amber to dark amber. The visual description gives 80 mm Pfund as the minimum. |
| Moisture | often above 18.5% | The guide gives no separate maximum for this profile. Relatively high moisture is common. The general EU requirement for ordinary blossom honey still applies, up to 20%. |
| Fructose and glucose combined | at least 60% | Consistent with a blossom honey despite its dark colour. |
| Sucrose | up to 5% | One of the sugars reported in the analysis. |
| Electrical conductivity | at least 0.60 mS/cm | A lower rather than an upper reference. This is a relatively mineral-rich honey. |
| Free acidity | up to 50 meq/kg | Particularly worth checking in higher-moisture lots. |
| HMF | up to 40 mg/kg | HMF increases with heat and time in storage. |
| Diastase activity | at least 8 Schade units | Indicator of enzyme activity, which can decline with heat. |
| Homogentisic acid | >200 mg/kg | A marker of botanical origin. Sensory research points instead to unedone as a major contributor to bitterness. |
| Arbutus pollen | at least 8% | This is a low pollen threshold. Strawberry tree contributes relatively little pollen to the honey. |
Reference ranges from the Guía de mieles monoflorales ibéricas, fourth edition (2023). These characterise the variety. Spanish statutory limits are set by Royal Decree 1049/2003 as amended by Royal Decree 68/2025, including a general maximum of 20% moisture and 40 mg/kg HMF, subject to the exceptions in the legislation.

Growing areas and harvest season
The guide identifies shaded sites in the mountain ranges of south-western and northern Iberia. The tree flowers in autumn, often just as the previous year’s fruits turn ripe. It offers one of the latest harvests of the season.
Strawberry tree honey flow
FloweringFlowering and harvest
The guide places the main harvest in autumn. It is one of the final flows of the year and relies on suitable autumn weather.
How to recognise strawberry tree honey
- 1Look for pronounced bitterness. It should be more evident than sweetness in the guide profile. Compare with traceability and other findings.
- 2Dark, from 70 mm Pfund upwards. The composition table gives this lower reference.
- 3Look for forest floor and mushroom notes. An earthy, autumnal aroma.
- 4An uneven set can occur. Uneven crystallisation can occur when the moisture is high.
- 5Ask about homogentisic acid. The guide’s value above 200 mg/kg supports botanical identification. It is not a measurement of bitterness.

Composition and health claims
Bitterness alone is no evidence of medicinal properties. EU rules govern health claims on food. The qualities of this honey can be described in terms of taste, origin and composition.
These characteristics matter when tasting or using the honey.
- Sweetness is secondary to bitterness. The honey still contains sugars.
- The guide gives a minimum conductivity of 0.60 mS/cm, consistent with a comparatively mineral-rich honey.
- It offers a late autumn flow when many other woodland flowers have finished.
- Blue cheese, game, dark chocolate and savoury sauces all offer contrasts for its bitter edge. It will give a very different result from a mild honey in sweet baking.
Who should take particular care?
Children under 12 months. Do not give honey to infants under one year. It can contain spores of Clostridium botulinum that may cause infant botulism. This applies to all types of honey.
Diabetes. honey is a source of sugars. This also applies to natural and monofloral honeys when planning a diet.
Known allergy. Anyone with a diagnosed allergy to honey or bee products should consult their clinician if unsure what is safe for them.
Frequently asked questions
Why is strawberry tree honey bitter?
Sensory research on the identified compounds points to unedone as a major contributor. Homogentisic acid is a useful marker of strawberry tree origin, a different question from the source of bitterness. The guide describes bitterness as dominant, with salty notes and sweetness in the background.
Is it normal for the honey to taste less sweet?
Yes. Perceived sweetness comes second to bitterness in this profile. This is a tasting difference and does not make it a low-sugar food.
Why has my strawberry tree honey set unevenly?
It often crystallises quickly and may have relatively high moisture, sometimes above 18.5%. Both can affect the texture. Keep the jar closed. If there are other signs of fermentation, check the lot rather than judging solely by crystal size.
When is it harvested?
In autumn, when many other woodland flowers have finished. The flowers often appear alongside fruit ripening from the previous year. It can be one of the season’s last harvests.
Who should take particular care?
Never give honey to babies under 12 months because of infant botulism risk. People with diabetes should count its sugars even though the honey tastes bitter. Anyone with a diagnosed allergy to hive products should seek individual medical advice.
Where to buy strawberry tree honey
We do not currently stock this honey. It is a short autumn harvest from shaded woodland, with a taste that appeals particularly to lovers of bitterness. Ask beekeepers in south-western Iberia or along the northern Atlantic coast. For a different dark, strong honey, see our raw heather honey.
