    Abstract:
    BACKGROUND: This study was carried out in order to investigate the role of post-harvest methods and roasting degree on the sensory profile of Turkish coffees and to compare the results between two sensory panels: Turkey and Brazil. Bourbon variety of Arabica coffee beans processed by three different post-harvest methods (natural, pulped natural and fully washed) and roasted at three different roasting degrees (light, medium and dark). RESULTS: Ground coffee in powder size was heated with cold water and prepared in a Turkish coffee machine. Twenty assessors - ten Turkish and ten Brazilian - were selected and trained to assess 20 flavor attributes of nine Turkish coffee samples. Sensory evaluation results showed that the effects of roasting method on flavor development were perceived more dominantly than effects of post-harvest methods. For the first time, this study highlighted the sensory analysis of Turkish coffees assessed by Turkish and Brazilian assessors. CONCLUSION: Turkish coffee flavor profiles were significantly influenced by roasting method and no significant effects of post-harvest method were observed. Sensorial properties of Turkish coffee were affected by several factors, such as geographical origin and techniques used for preparation of coffee beans, cultural tradition, lifestyle, social behavior and habit. © 2021 Society of Chemical Industry.
