The present invention provides a new production method suitable for a container-packed green tea beverage for warm sales. A process of adding silica to a tea extract obtained by extracting green tea leaves to adsorb the oli component in the tea extract onto the silica, and then removing the silica to remove the silica is carried out for a green tea beverage. Put into production process. By adding silica to the tea extract and bringing it into contact, it is possible to selectively adsorb and reduce the proteins and polysaccharides that are the secondary cause of sediment, and to prevent the occurrence of soil even during warm sales. Moreover, a lot of flavor components can be left. Further, a large amount of catechins can be left in the beverage, and the growth of heat-resistant bacteria can be suppressed by the antibacterial action of the catechins. Furthermore, while the fatty acid oxidative degradation product causing the deterioration odor can be selectively reduced, a large amount of roasting fragrance components such as pyrazine can be left.
