PURPOSE:To obtain a green tea drink having improved hue, flavor, etc., by extracting green tea leaves with hot water under specific conditions, adding sodium ascorbate thereto in (after) extraction, filling the extract in a container, and replacing the residual air with nitrogen gas. CONSTITUTION:Green tea leaves, e.g. SENCHA (green tea leaves of middle grade), are extracted with hot water containing a sugar ester at 40-80 deg.C, and sodium ascorbate is added thereto in or after the extraction. The resultant green tea extract is then filled in a container, and the residual air is replaced with nitrogen gas. The green tea extract is heat sterilized to give the aimed green tea drink having improved antimicrobial properties and little change with time. The above-mentioned green tea is preferably other than fermented green tea and semifermented green tea.
