The amount and composition of phenolic compound of grapes and wines vary
greatly with the grape variety, seasonal condition, production area and vinification
process. Therefore, the objectives of this work were to preliminarily evaluate and
compare phenolic contents and antioxidative properties of some grape and wine
varieties produced in Thailand, particularly grown and produced on Suranaree
University of Technology (SUT) Farm and to investigate changes of phenolic
compounds during vinificantion process due to different yeast strains and added
t-resveratrol.
