By containing non-polymer catechins in high concentration, the physiological effects of the catechins are manifested, minerals indispensable to the living body are fortified, and the storage stability of a beverage is improved. A packaged beverage containing: (A) from 0.05 to 0.5 % by mass of non-polymer catechins； (B) from 0.0012 to 0.12 % by mass of calcium； (C) from 0.00012 to 0.006 % by mass of magnesium； (D) from 0.000048 to 0.0024 % by mass of zinc； (E) from 0.00004 to 0.002 % by mass of iron； and (F) from 0.01 to 20 % by mass of a sweetener, wherein a content mass ratio [(B)/(A)] of the calcium (B) to the non-polymer catechins (A) is from 0.001 to 1.0； (J) a percentage of gallate bodies in the non-polymer catechins is from 5 to 55 % by mass； and pH is from 2.5 to 5.1.本發明提供一種容器裝飲料，其藉由含有高濃度之非聚合物兒茶素類，而表現出兒茶素類之生理效果，並加入有人體不可或缺之礦物質而進行強化，且提高飲料之保存穩定性。該容器裝飲料中包含：(A)0.05~0.5質量%之非聚合物兒茶素類；(B)0.0012~0.12質量%之鈣；(C)0.00012~0.006質量%之鎂；(D)0.000048~0.0024質量%之鋅；(E)0.00004~0.002質量%之鐵；以及(F)0.01~20質量%之甜味劑；且(B)鈣與(A)非聚合物兒茶素類之含有質量比[(B)/(A)]為0001~1.0，(J)非聚合物兒茶素類之沒食子酸酯體的比率為5~50質量%，pH值為2.5~5.1。
