Sarı Ulak Olive Oil: The Royal Olive of Çukurova
March 2026 · 10 min read
On the southern foothills of the Çukurova Plain, atop the calcareous soils of Tarsus, an olive variety has thrived for centuries: Sarı Ulak. Also known locally as the "Tarsus olive," this dual-purpose variety — suitable for both table consumption and oil extraction — is one of the region's most prized agricultural heritages. Granted geographical indication (GI) protection for the olive in 2018 and for the oil in 2021, Sarı Ulak is the torchbearer of Tarsus's olive-growing identity. A common saying in the region goes: "Planting any sapling other than Sarı Ulak is betrayal."
Geography and Terroir
Sarı Ulak grows in the Tarsus district of Mersin, where an Eastern Mediterranean climate prevails. Long, hot summers, mild winters, calcareous soil composition, and moisture carried from the Mediterranean Sea are the fundamental elements shaping this variety's character. The region diverges markedly from Aegean olive-growing: Sarı Ulak has a rounder, warmer, and more herbaceous profile.
In the village of Karadiken in Tarsus stands an 820-year-old monumental Sarı Ulak tree. This tree is living proof of the variety's deep-rooted history in the region, demonstrating just how intertwined olive cultivation is with the soils of Tarsus.
Dual Identity: Table Olive and Oil
Sarı Ulak's most distinguishing feature is its dual-purpose nature. As a table olive, it bears the title "king of olives." With 22–23% oil content, it carries value both at the table and in the press.
The most well-known table form is kırma zeytin (hand-cracked olive) — prepared by hand-cracking without any chemical sweetening. This method preserves the olive's natural flavor profile and is an indispensable part of Tarsus cuisine.
Official GI Quality Table
| Parameter | Average Value | EVOO Limit |
|---|---|---|
| Peroxide Value (meqO₂/kg) | 8.23 | <20 |
| Free Fatty Acidity | Within EVOO standard | <0.8% |
| Colour | Bright yellow | — |
| Total Phenols | High | >250 mg/kg (EFSA threshold) |
Polyphenols: Sarı Ulak's Secret Weapon
Officials from the Tarsus Agriculture Directorate have emphasized that Sarı Ulak olive oil's polyphenol content is markedly higher than other varieties in the region. Samples from the village of Büyükkösebalcı, in particular, have recorded the highest polyphenol values.
The European Food Safety Authority (EFSA) has approved the use of the health claim "contributes to the protection of blood lipids from oxidative stress" for olive oils with polyphenol content above 250 mg/kg. Sarı Ulak olive oil is among the varieties that comfortably exceed this threshold — making it a strong candidate in the health-focused premium market.
Sensory Profile
Sarı Ulak olive oil carries a distinctive character that reflects the warm Mediterranean climate:
- Appearance: Bright yellow-gold colour
- Nose: Grass, green fruit, and floral aromas
- Palate: Soft fruity entry, honest but not aggressive bitterness
- Finish: Medium peppery pungency
- Intensity: Medium
In the kitchen: Ideal as a finishing oil over salads, for braised dishes, salad dressings, and traditional Tarsus cuisine. Its lack of an aggressive bitterness profile makes it an accessible choice for those new to olive oil.
A Brief History of Sarı Ulak
For many years, Turkey's "Gemlikleştirme" (Gemlik-ification) policy encouraged replacing local varieties with Gemlik saplings. This policy directly impacted Sarı Ulak — thousands of Sarı Ulak trees were uprooted and replaced with Gemlik saplings.
Over time, however, the approach proved counterproductive. The Gemlik variety could not adapt to Tarsus's hot climate and calcareous soils. The Ministry now pursues the opposite strategy: research programs are underway to develop higher-yielding Sarı Ulak clones. The story of Sarı Ulak is not one of disappearance, but of rediscovery.
Geographical Indication Status
Sarı Ulak olive oil received geographical indication registration on 25 May 2021 under Registration No: 767. The registration holder is the Tarsus Commodity Exchange.
What Does a Geographical Indication Mean?
- Origin guarantee: Only olive oil produced in Tarsus can bear this name
- Quality standard: Compliance with established quality parameters is mandatory
- Imitation protection: The GI provides legal safeguard for the product

Frequently Asked Questions
Why is Sarı Ulak also known as the "Tarsus olive"?
Sarı Ulak is native to the Tarsus district, and locals have long referred to it as the "Tarsus olive." The geographical indication registration officially confirms this bond.
What does "dual-purpose" mean?
A dual-purpose variety means the olive can be consumed directly at the table (cracked olives, brined) and also pressed into high-quality olive oil. This gives producers market flexibility.
What does the GI registration mean for buyers?
A geographical indication means origin guarantee, quality standard, and imitation protection. Buyers can be assured that a product labelled Sarı Ulak was genuinely produced in Tarsus and meets established quality criteria.
Why is the polyphenol content so high?
The hot Mediterranean climate of Tarsus, calcareous soils, and the variety's genetic makeup combine to enable high polyphenol accumulation. Fruits harvested in the early season yield the highest phenolic values.
Why is Sarı Ulak a strategic choice for importers?
Sarı Ulak is one of the rare varieties with dual GI registration — for both the olive and the oil. Tarsus's historical recognition — a cultural context stretching from Cleopatra to St. Paul — offers the product a compelling narrative. High polyphenol content and health-claim potential provide tangible advantages for premium market positioning.
