Comparison of Characteristics and Consumer Preferences of Black Tea Made from Land Race and Beachwisull

This study surveyed the post-making processing characteristics and consumer preferences of traditional Korean black tea using Beachwisull, a domestic tea tree cultivar developed to grow competitive Korean black tea in the growing global tea market after COVID-19. In terms of ingredient characteristics, Beachwisull was higher overall than landrace tea, except for the free amino acid and caffeine content. As a result of a preference survey targeting foreigners residing in Korea who enjoy drinking black tea, there was no significant difference in taste characteristics between the landrace tea and Beachwisull tea. On the other hand, the color needed to be supplemented, which can be improved during the black tea manufacturing process.
