PROBLEM TO BE SOLVED: To provide a green tea excellent in color tone stability and flavor stability during storage, enabling the brilliant green color, flavor, and other active ingredients inherent to green leaves to be preserved.SOLUTION: The manufacturing method of a green tea includes adding one or more alkaline solutions selected from sodium bicarbonate, sodium carbonate, potassium carbonate, sodium hydroxide, and potassium hydroxide in a manufacturing process of dried tea leaves. The produced green tea is pulverized, to which water in an amount of 133 times the weight of tea leaves is added to make a suspension. On that occasion, the pH is adjusted to the range of 6.8 to 8.0. Consequently a green tea excellent in color tone stability and flavor stability during storage can be provided, enabling the brilliant green color, flavor, and other active ingredients inherent to green leaves to be preserved.
