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.비중합체 카테킨류를 고농도로 함유함으로써, 카테킨류의 생리 효과를 발현시킴과 함께, 인체에 반드시 필요한 미네랄을 강화하고, 음료의 보존 안정성을 향상시킨다. (A) 비중합체 카테킨류 0.05 ∼ 0.5 질량%, (B) 칼슘 0.0012 ∼ 0.12 질량%, (C) 마그네슘 0.00012 ∼ 0.006 질량%, (D) 아연 0.000048 ∼ 0.0024 질량%, (E) 철 0.00004 ∼ 0.002 질량%, 및 (F) 감미료 0.01 ∼ 20 질량% 를 함유하고, (B) 칼슘과 (A) 비중합체 카테킨류의 함유 질량비 [(B)/(A)] 가 0.001 ∼ 1.0 이고, (J) 비중합체 카테킨류의 갈레이트체율이 5 ∼ 55 질량% 이고, pH 가 2.5 ∼ 5.1 인 용기에 담은 음료.
