Table grapes and raisins can be consumed by processing in many ways such as wine, grape juice, vinegar and molasses in the food industry. Besides, in different regions in Turkey, it is the raw material of local products such as köfter, grape sausage, pestil, hardaliye and so on. In addition to these, the leaves of the grapevine are used in the production of ‘sarma’, which has an exceptional place in Turkish cuisine, and transform into a distinct flavor, create an important economic value for producers. Brined vine leaf production is a method of preservation and storage that has been going on for centuries in Anatolia (Winkler et al., 1974). This commercial value of grapevine leaves has required to mark the harmony of the local ecology and the difference of the product quality. In this context, as a result of the application of the Erbaa Chamber of Industry and Commerce in Tokat province, "Erbaa Narince Vineyard Leaf" was registered as a geographical sign on 5 th of December 2017 in the type of origin name (TUIK, 2017). The application of the leaf of Yapıncak grape variety by the Süleymanpaşa Chamber of Agriculture in Tekirdağ province with the same purpose was registered as "Tekirdağ Yapıncak Brined Grapevine Leaf" on 28 th of October 2020. It is desirable that the leaves to be pickled should be thin, less hairy, and as whole as possible without slices. Today, the most preferred and prominent varieties in the production of brine and canned grapevine leaf in Turkey are Sultani Çekirdeksiz in the Aegean region, Narince in the Mehmet Ali Kiracı 1* ,Mehmet Ali Şenol 1 ,Uğur Akdemir 1 1 Tekirdağ Viticulture Research Institute How to cite: Kiracı, M.

Viticulture Studies (VIS), 2(1), 13– 23. https://doi.org/10.52001/vis.2022.7.13.23 Abstract This study aims to determine the production model providing the maximum economic benefit to the producers by comparing the harvesting models comprising different amounts of grape load and different number of harvested leaves of Yapıncak variety. This variety is one of the important grape varieties whose leaves are evaluated as edible/pickled. 12 different production models, 10 models targeting grape and leaf harvesting together, and 2 models harvesting only leaves and only grapes were established in the trial vineyard consisting of vines of the same age. Production and variable costs, gross production values (GPV), gross and net profits and proportional profitability were calculated for the unit area of production models. The study was conducted in 2018 and 2019 years. In 2018, the production model in which all the grapes were not harvested and the leaves were harvested 5 times had the highest values with a net profit of 1.166,5 TRY and proportional profitability of 1.57. In 2019, the model, in which grapes were harvested at a rate of 50% and the leaves were harvested 7 times, became the economically recommended variety for producers with a net profit of 4.664,3 TRY and proportional profitability of 2.69. It has been determined that although the quality of the grapes decreases as the number of grapes which are not harvested in the grapevines increases, the quality of the leaves has not decreased due to the number of harvests.
