Yalova Chestnut Honey, or Yalova Kestane Balı, is one of the province’s most distinctive local foods. It is produced from colonies positioned within or close to Yalova’s chestnut forests, where bees forage during the intense early-summer flowering period. The protected product is closely associated with the province’s forest ecology, long-established beekeeping knowledge, and the presence of chestnut together with smaller amounts of linden and other local flora.
Yalova Kestane Balı received Turkish geographical-indication registration in 2024 as a mahreç işareti. The official specification links the honey with Yalova Province through its reputation, production method, pollen composition, chemical characteristics, and the requirement that production and packaging — apart from wintering the colonies outside the province — take place within the defined geographical area.
The protected specification requires at least 74% sweet-chestnut pollen in the honey.
Colonies are positioned for the chestnut season in spring, with honey processing concentrated in the second half of June.
Production hives must be placed inside chestnut forests or no more than 600 metres from them.
Yalova Kestane Balı has been registered by TÜRKPATENT as a mahreç işareti since 2024.

How Yalova’s wooded landscape and beekeeping tradition came together in a protected local product.
Yalova may be compact in size, but much of its landscape is shaped by forest. The steep southern parts of the province are particularly wooded, and broad-leaved trees form an important part of this vegetation. Chestnut, linden, hornbeam, oak and other species create a rich seasonal forage environment for bees.
Chestnut flowering is especially important for local beekeepers. Colonies that have spent the colder months in warmer areas are brought back to Yalova in spring and positioned close to chestnut forests before the main flowering season. The official geographical-indication specification requires production colonies to be established in their production areas by mid-May.
During early summer, bees collect nectar and pollen from the chestnut-dominated forest flora. The resulting honey is characterised not only by its strong connection with sweet chestnut but also by smaller traces of other plants, including linden. Local agricultural authorities frequently highlight this combination when describing the comparatively smooth character of Yalova’s chestnut honey.
Yalova’s beekeeping sector has also developed around seasonal hive movement, organised production areas, honey extraction, filtration, resting, packaging, quality control, producer cooperation, and projects supporting safer and more sustainable apiculture.
The product’s reputation and its connection with the province were formally recognised when Yalova Kestane Balı was registered by the Turkish Patent and Trademark Office on 23 January 2024. The registration protects a honey whose identity is inseparable from Yalova’s chestnut forests and local production practices.
The protected product is defined by its forest source, pollen profile, beekeeping method, analytical values, and close geographical connection with Yalova.
The most important botanical marker is sweet chestnut, Castanea sativa, whose pollen must account for at least 74% of the registered honey’s pollen profile.
The specification also requires the presence of linden pollen. This reflects the mixed broad-leaved forest environment in which the chestnut season takes place.
Production colonies must be positioned inside chestnut forests or within a maximum distance of 600 metres from them during the honey season.
The geographical-indication specification permits Caucasian bees, Anatolian bees, and hybrids of these populations for registered production.
Chestnut honey is known for a pronounced forest character. Yalova agricultural sources describe the local product as having a comparatively soft taste and a distinctive aroma, with its mixed forest flora contributing additional nuance.
Registered Yalova Chestnut Honey must meet a minimum proline value, one of the analytical parameters used in assessing the product’s conformity.
The specification sets a minimum electrical-conductivity value of 0.8 mS/cm, reflecting the mineral and organic-acid profile expected from the registered honey.
The name Yalova Kestane Balı is protected through a Turkish geographical indication that defines how and where the product is produced, processed, and packaged.
Yalova Kestane Balı is officially registered by the Turkish Patent and Trademark Office as a geographical indication with the status of mahreç işareti. The registration protects a product whose reputation, botanical profile, production method, and local beekeeping tradition are strongly connected with Yalova Province.
The official protected name is Yalova Kestane Balı.
The geographical-indication registration number is 1525.
The registration was completed on 23 January 2024.
The product is registered as a mahreç işareti, a Turkish geographical-indication category protecting its established connection with Yalova.
The defined geographical boundary is Yalova Province.
The registration holder is the Yalova Province Beekeepers’ Association.
The specification defines the permitted bee populations, hive type, seasonal movement of colonies, placement near chestnut forests, pollen thresholds, analytical values, extraction process, resting and packaging procedures, storage conditions, geographical boundaries, and inspection requirements.
Yalova’s combination of wooded slopes, humid Marmara conditions, broad-leaved forest vegetation, and long-established beekeeping creates an especially suitable setting for chestnut-honey production. The province’s southern landscape is heavily forested, while chestnut grows alongside linden, hornbeam, oak, dogwood and many other nectar- and pollen-producing plants.
Sweet-chestnut stands provide the dominant pollen and nectar source that gives the protected honey its identity.
Linden and other forest species contribute smaller pollen components and help distinguish Yalova’s seasonal forage landscape.
The province’s southern terrain carries dense forest cover, creating extensive areas suitable for seasonal apiaries.
Local producers combine seasonal hive movement, forest placement, careful extraction, filtration, resting, packaging, and quality control.
Yalova Chestnut Honey follows a seasonal beekeeping rhythm rather than a fruit-growing calendar. Colonies are wintered in warmer areas, returned to Yalova during spring, positioned near chestnut forests before flowering, and harvested after the main early-summer honey flow.
The most important production period falls in early summer. Colonies are already established close to chestnut woodland before the flowering peak, and the protected production method specifies that combs are taken from the hives and processed between 15 and 30 June.
Beekeepers return their colonies to Yalova during April and May and position them in approved production areas.
The key nectar-and-pollen flow comes from the early-summer flowering of sweet-chestnut trees and associated forest flora.
The protected production method identifies 15–30 June as the period when combs are removed and processed.
After filtering, the honey is left in a settling tank for roughly two to three days before packaging.
For travellers hoping to see active beekeeping or a honey harvest, arrangements should always be made in advance. Apiaries are working agricultural sites, and access must be controlled for both visitor safety and colony protection.
Yalova Chestnut Honey has the pronounced, aromatic personality associated with chestnut-based honeys, but local agricultural sources particularly describe the Yalova product as comparatively smooth in taste. Its chestnut-dominant pollen profile is accompanied by smaller amounts of linden and other forest plants, creating a layered flavour rather than a simple one-flower sweetness.
The honey has a noticeable forest-floral aroma rather than the very mild scent of delicate spring blossom honeys.
Chestnut gives the honey a deeper and more assertive character than many light-coloured floral honeys.
Official Yalova sources describe the local honey as softer in taste than many other chestnut honeys.
The required presence of linden pollen reflects the mixed forest flora surrounding the chestnut stands.
Taste can vary naturally from season to season because flowering conditions, weather, hive location, and the exact balance of accompanying forest plants all influence a honey crop.
One of the clearest ways the registration defines Yalova Chestnut Honey is through pollen analysis. The protected product must show a strongly chestnut-dominated profile while also containing minimum traces of several other botanical groups.
These thresholds help connect the honey with the ecology of Yalova’s chestnut-dominated forest environment and form part of the conformity controls for the geographical indication.
The geographical-indication document sets measurable physical and chemical parameters for registered Yalova Chestnut Honey. These values are used together with pollen analysis and production controls to verify conformity.
Maximum moisture content: 20%.
Minimum combined fructose and glucose: 62 g per 100 g.
Required ratio: 1.10–1.40.
Maximum free acidity: 45 meq/kg.
Minimum electrical conductivity: 0.8 mS/cm.
Minimum diastase number: 8.
Maximum hydroxymethylfurfural value: 40 mg/kg.
Minimum proline value: 540 mg/kg.
The registered method combines migratory beekeeping with tightly defined forest placement. The goal is to bring strong colonies into Yalova before chestnut flowering and ensure that the bees forage within the chestnut-rich landscape associated with the product.
The production specification identifies Langstroth-type hives for registered beekeeping.
Colonies may winter in warmer nearby areas before returning to Yalova in spring.
Colonies should be established in production areas no later than 15 May so they can adapt before flowering.
Production hives must be located within chestnut forest or at most 600 metres away.
Honey is removed from uncapped frames with a manual or electric centrifugal extractor after the wax cappings are taken off.
Filtration, resting and packaging are controlled to protect the honey from contamination, excessive heat and unwanted odours.
After the honeycombs are removed during the June production period, the honey is processed using a sequence designed to separate it cleanly from the comb while preserving its natural characteristics.
Honey changes naturally during storage, and temperature has an important effect on colour, crystallisation and chemical quality. The geographical-indication specification therefore includes practical storage conditions for the protected product.
Store honey in a clean, dry environment and keep the container properly closed.
Honey should be kept away from odour sources because it can absorb surrounding smells.
Direct sunlight should be avoided during storage and distribution.
The protected specification calls for storage at temperatures not exceeding 25°C.
Under the specified conditions, the registration allows storage for up to two years from the filling date.
If honey crystallises, gentle warming in water below 38°C can return it to a more fluid state; the container should never be heated directly over a flame.
Beekeeping is an important part of Yalova’s agricultural landscape. Chestnut honey connects forest resources with seasonal labour, hive management, queen and colony care, extraction, packaging, laboratory testing, marketing, producer organisations and rural livelihoods.
The Yalova Province Beekeepers’ Association plays a central role in representing local producers and holds the geographical-indication registration.
Chestnut flowering creates an important seasonal production opportunity for beekeepers working around Yalova’s wooded areas.
The geographical indication adds formal controls covering origin, production method, pollen composition and product characteristics.
