Ahmet Hamdi Ersoy was an olive trader, sending baskets of olives by boats and other vessels from his home in Gemlik to his brother, Osman Ersoy, in İstanbul.


Ahmet Hamdi Ersoy sent his middle son İbrahim Ersoy to İstanbul to open one of İstanbul’s first olive shops.


Discerning the need in the pickle market, the Ersoy and Tüfekçioğlu families bought two thousand square meters in Gedelek Village in the Orhangazi District of Bursa, and founded the Zey-Tur-San company.


Zey-Tur-San started production.


Zey-Tur-San produced the first pasteurized pickles in the country of Turkey.


Zey-Tur-San started producing under the Berrak brand.

In the same year, Zey-Tur-San shipped the first pasteurized pickle, as an export of Turkey to Germany.


Zey-Tur-San renewed the logo for Berrak brand.


Zey-Tur-San partnered with Poupon Reitzel Industries Holding (P.R.I.Group) Reitzel, Switzerland’s 100-year-old pickle, vinegar, and mustard company.


Zey-Tur-San started customized productions by making agreements with world famous fast food chains.


The production area of the factory was extended to 25 thousand m2 and the annual vegetable processing capacity was raised to 8 thousand tons.


Due to the İstanbul-İzmir Highway Project, the facility in Gedelek was expropriated. The construction of 86 thousand m2 new factory was started in Gemiç. One acre wooded area of the land was made into a living space for orphaned animals.


ZTS launched the www.tursu.com.tr webpage in order to sell Berrak products on the Internet.


ZTS renewed the Berrak logo and its own corporate identity. Same year, our Berrak became the sponsor of Altın Elbiseli Adam [Man in Golden Suit] TV show at Skytürk.


 We started manufacturing the EV brand.


The BPlas Company belonging to the Gökçen Family, one of the most respected families of Turkey, with 150 years of experience in industrial production, became ZTS’s partner by purchasing majority shares. BPlas is the largest automotive parts supplier in Turkey. BPlas was established in 1987 under the management of Honorable Celal Gökçen.


The manufacturing capacity in the Gemiç facility doubled.


We offered our Berrak brand for sale at hepsiburada.com, n11.com and Getir. Our capacity increased to 9000 tons with orders from all over the world. In the same year, we started sponsoring veterinary clinics through HAYTAP (Animal Rights Federation) to support the treatment of orphaned animals, with the motto “All Beings Are One”.


Zey-Tur-San became the sole pickle supplier of one of the world’s biggest fast food chain in Europe, Middle East and Africa, excluding Germany. Its production capacity was also increased to 15.000 tons of vegetables.



Finally ZTS made another dream come true by producing BERRAK PICKLE JUICE both in spicy and non-spicy tastes. This traditional Turkish drink accepted as one of the healthiest SPORTS DRINKS of our time. Currently sold in MİGROS nationwide. Again pasteurized, both preservative and additive free.
