Chestnut honey is a type of honey produced when bees collect and process nectar and pollen from the flowers of the chestnut tree (Castanea sativa). It generally has a dark color ranging from dark brown to nearly black and can exhibit amber tones. Its taste is described as slightly bitter, astringent, and characterized by a strong herbal aroma. The sweetness is lower compared to other types of honey, and thanks to its high fructose content, it is resistant to crystallization. Even when crystallized, it forms very fine granules, making it easily distinguishable from other honeys. The tannins present contribute to its unique aromatic and slightly bitter flavor.
In addition to its nutritional value, chestnut honey is classified as a functional food due to its biochemical content. It is known for its antiseptic properties, and many studies have been conducted on its antibacterial and antiviral effects. Notably, its high antioxidant capacity has positive health benefits such as strengthening the immune system and supporting the respiratory and digestive systems.

Geographical Indications
In Turkiye, chestnut honey is produced in regions where chestnut trees are abundantly cultivated. Foremost among these areas is the Black Sea Region. In particular, the coastal areas of the Black Sea are among the most suitable for chestnut honey production due to their favorable climate and geography. The provinces of Ordu, Giresun, Artvin, Kastamonu, Bartın, Sinop, Zonguldak, Samsun, and Rize stand out as the most common production areas for chestnut honey.
Chestnut honey is also produced in other regions of Turkiye, such as in the Marmara Region—including Bursa, Yalova, Balıkesir, and Çanakkale—and in the Aegean Region, such as İzmir and Aydın. In Bursa, especially in the districts of İnegöl, Karacabey, and Mustafakemalpaşa, chestnut honey is produced intensively. The antioxidant capacity and pollen content of honey in these regions vary according to local geographical conditions.
Certain regions in Turkiye have received geographical indication registration for chestnut honey. Chestnut honeys protected by geographical indication, as designated by the Turkish Patent and Trademark Office, include:
- Zonguldak Chestnut Honey (Designation of Origin)
- Sinop Chestnut Honey (Designation of Origin)
- Rize Chestnut Honey (Designation of Origin)
- Yalova Chestnut Honey (Designation of Origin)
- Kastamonu Chestnut Honey (Designation of Origin)
The common feature of these honeys is that they possess a taste, aroma, and biochemical profile determined by the region's climate, vegetation, and beekeeping practices. These geographical indications are regarded as important criteria that guarantee the product’s authenticity and quality to the consumer.
Antioxidant Potential
The antioxidant potential of chestnut honey is derived from various biochemical compounds, primarily phenolic compounds and flavonoids. This type of honey exhibits higher antioxidant activity compared to many other types of honey. The antioxidant components vary according to the geography and vegetation of the production area. Research in Turkiye has identified Bursa’s Kurşunlu district as one of the regions where chestnut honey exhibits the highest antioxidant potential. The total antioxidant capacity of chestnut honey obtained from this region has been found to be higher than that from other areas in the country.
Antioxidants play a role in preventing health problems caused by oxidative stress. Oxidative stress occurs as a result of the accumulation of free radicals in cells, which can lead to issues such as a weakened immune system, heart disease, diabetes, and cancer over time. Chestnut honey, with its antioxidant compounds, helps combat these free radicals, thereby reducing oxidative stress. Studies indicate that regular consumption of chestnut honey may be beneficial for strengthening the immune system, reducing inflammation, and increasing resistance to infections.
Additionally, the dark color of chestnut honey is considered an indicator of its high antioxidant content. Many studies support that dark-colored honeys generally possess higher therapeutic properties and antioxidant capacities, distinguishing chestnut honey as a functional food.
Gastronomic Usage
In European gastronomy, chestnut honey is frequently paired with cheese platters, rustic breads, or lightly sweet cheeses such as ricotta. It is also used as a sweetener in walnut or almond breads, on toast, and in crackers. The use of chestnut honey is common in desserts such as cakes, cookies, tarts, and ice cream. Its gastronomic applications are not limited to sweets; chestnut honey can be used as a flavor enhancer and tenderizer in meat marinades, particularly for game meat, chicken, and red meat. It is also ideal for glazing meats or flavoring roasted vegetables.
In Turkiye, however, the gastronomic use of chestnut honey is still somewhat limited compared to Europe and is generally consumed in its plain form. Typically spread on bread, chestnut honey in Turkiye has not yet fully exploited its gastronomic potential, as its use is primarily focused on health benefits. Nevertheless, in recent years, with increased culinary awareness and the search for new flavors, the use of chestnut honey in desserts, salad dressings, hot and cold beverages, and meat dishes has begun to rise.
