The present invention relates to a packaged beverage of high catechin content, wherein (a) it contains from 55 to 90 wt % of non-polymer catechins based on a solid content of the purified product of green tea extract, and (b) when the purified product of green tea is formed into an aqueous solution containing the non-polymer catechins at a concentration of 1 wt %, the aqueous solution has a b* value of from 39 to 10 as measured by a calorimeter and a total light transmittance (.tau.t) of from 83% to 95% as measured by a turbidometer, and wherein the content of the non-polymer catechin in which the purified product of the green tea is incorporated is from 0.06 to 1.0 wt %. The packaged beverage of the present invention contains non-polymer catechins at a high concentration, has a good flavor and taste, remains free from the formation and settling of precipitates over a long period of time, and is suited for long-term drinking.
