drink tea. Aside from health benefits, the sensory properties of tea such as taste, aromas, mouthfeel, and
astringent levels were also reported to determine the choice of tea consumption [8]. Sensory attributes
perceived through gustatory and olfactory perception become a major determinant factor for consumers'
acceptability of tea products [9].
In the market, RTD tea can be segmented as liquid RTD, concentrated syrup, and premix (powdered)
tea, and among these segments, liquid RTD tea is the most consumed and has a steady growth. The
objective of this study is to investigate the driver of liking for RTD tea based on its sensory profiles. The
different RTD tea based on type and flavors were involved in this research and there was no study has
investigated the preferences for RTD tea products involving different RTD tea types (green, black,
jasmine), sweet options (sweetened, unsweetened, less sweet), and flavors (floral, fruity, milk)
previously. This study aligned with the sustainable development goals (SDGs) related to health and well-
being.

the market. A total of 12 RTD teas were selected and evaluated in this study All the samples were
purchased from local supermarkets and were considered as popular and recognized brands in Indonesia.
