An object of the present invention is to provide a non-polymer catechin-containing container-packed beverage that suppresses the enhancement of astringency and has little astringency even after long-term storage. The following components: (A) 0.025 to 0.5% by mass of non-polymer catechins, and (B) at least one selected from α acids and iso α acids, and β acids. The container-packed drink whose mass ratio [(B2) / (B)] of (B2) (beta) acid with respect to a component (B) is 0.01 or more, and pH is 2-5.
