Erdek Kapıdağ Olive Oil

Erdek Kapıdağ Olive Oil is a distinctive olive oil produced in the Erdek district of Balıkesir Province, within Türkiye’s Marmara Region, under the unique geographical and climatic conditions of the Kapıdağ Peninsula. This product was officially registered with a geographical indication by the Turkish Patent and Trademark Office on 6 May 2025, shaped by local olive varieties, traditional production techniques, and regional knowledge.

Geographical and Agricultural Characteristics

The Kapıdağ Peninsula is a landmass extending into the Sea of Marmara, offering an ecosystem favorable for olive cultivation due to its microclimate. The region’s mild maritime climate, permeable soil structure, and high levels of sunlight enable olive trees to produce both abundant and high-quality fruit. These natural advantages directly influence the sensory and chemical properties of the olive oil.

Production Process and Techniques

Olive harvest occurs during the early harvesting period, using hand-picking or pole-harvesting methods. The olives are processed within a maximum of 24 hours. The production process employs only mechanical methods; no chemical treatments are applied. Olives are transformed into oil using the cold-press method at a maximum temperature of 27°C. The olive oil is stored in stainless steel tanks with complete isolation from air. The production stages are as follows:

• Harvest: Conducted between October and December, according to the ripeness of the olives.
• Sorting and Washing: Harvested olives are separated from leaves and foreign matter and washed with clean water.
• Crushing and Malaxation: Olives are crushed into a paste and then kneaded to facilitate oil separation.
• Pressing: The paste is pressed using vertical or horizontal presses to separate oil from water.
• Separation: Centrifugation is used to separate oil from water and pomace.
• Storage: The extracted olive oil is rested in tanks protected from light and air exposure.

Sensory and Chemical Properties

Erdek Kapıdağ Olive Oil is recognized by its fruity aroma, medium pungency and bitterness, and its color ranging between golden yellow and greenish hues. Sensory analyses highlight associations with fresh grass, almond, and green olive. Chemically, it exhibits low free fatty acid content and high polyphenol levels, which extend its shelf life and enhance its antioxidant capacity.

Control System

For Erdek Kapıdağ Olive Oil to be marketed as a geographically indicated product, its production process is monitored through control mechanisms approved by the Turkish Patent and Trademark Office. These controls aim to verify compliance of both production stages and the final product with established technical criteria. Specifically:

• The frequency and methodology of inspections follow the principles outlined in the registration certificate.
• Inspection activities are coordinated by the Erdek Chamber of Commerce.
• Producers are required to operate within the defined geographical boundaries and using the specified methods.
• Product samples undergo sensory and chemical analyses to ensure quality control.
• In cases of non-compliance, the right to use the geographical indication may be suspended.

This control system aims to safeguard the product’s distinctive characteristics and guarantee consumers a safe and authentic olive oil.

Cultural and Economic Value

Olive cultivation on the Kapıdağ Peninsula is a centuries-old agricultural tradition deeply interwoven with the lifestyle of the local population. Olive oil production is not merely an economic activity but also a cultural heritage. The geographical indication registration and its associated control system aim to preserve this heritage and enhance the product’s recognition in national and international markets.
