History of the Brand. In 1970, Ibrahim Halil Kozlu who was born in Gaziantep, and his 5 sons (Fahrettin, Hasan, Mustafa, M.Hanifi and Bilal kozlu) started their business in Tomato paste. Thus, they established the bedrock of its production for commercial purposes. This business started with successfully selling the Tomato paste produced by committed, trustful, experienced staff in Gaziantep villages by wholesale and retail in and around Gaziantep. Due to the excellent quality paste produced by Acemoğlu, the sales scale started to grow and expand significantly. Consequently, the demand on paste produced in the villages of Gaziantep has grown and increased. As a result, Acemoğlu family started the establishment of Öncü brand. Within a very short time, the family put its plan into practice and expanded their business in homemade type tomato and pepper paste by establishing a full scale factory in 1998, to be the very first company to produce homemade type tomato and pepper paste in Turkey, following strict hygiene and safety rules.
