1. A packaged beverage, wherein: said packaged beverage comprises from 0.092 to 0.5 wt % of non-polymer catechins, and has(a) a content of gallates in said non-polymer catechins of from 45 to 60 wt %,(b) a weight ratio of said non-polymer catechins to caffeine of from 8 to 40,(c) a weight ratio of s
1. A packaged beverage, wherein: said packaged beverage comprises from 0.092 to 0.5 wt % of non-polymer catechins, and has(a) a content of gallates in said non-polymer catechins of from 45 to 60 wt %,(b) a weight ratio of said non-polymer catechins to caffeine of from 8 to 40,(c) a weight ratio of said non-polymer catechins to (sucrose+glucose) of from 2 to 15, and(d) dietary fibers amount to 0.5 wt % or less of a solid content. 2. The packaged beverage according to claim 1, wherein said packaged beverage is prepared by adding a green tea extract to a beverage and wherein said green tea extract is prepared by a process comprising dissolving a caffeine-containing catechin composition in a 9/1 to 1/9 by weight mixed solution of an organic solvent and water, and then bringing the resultant solution into contact with activated carbon to selectively remove caffeine. 3. The packaged beverage according to claim 1, wherein said packaged beverage is prepared by adding a green tea extract to a beverage and wherein said green tea extract is prepared by a process comprising dissolving a caffeine-containing catechin composition in a 9/1 to 1/9 by weight mixed solution of an organic solvent and water, and then bringing the resultant solution into contact with activated carbon and also acid clay or activated clay to selectively remove caffeine. 4. The packaged beverage according to claim 1, wherein said packaged beverage is prepared by adding a green tea extract to a beverage and wherein said green tea extract is prepared by a process comprising dissolving a solid caffeine-containing catechin composition in a mixed solution comprising ethanol and water in a ratio ranging from 9/1 to 1/9 by weight, wherein said ratio is the ratio of ethanol to water in the mixed solution, bringing the resultant solution into contact with activated carbon allowing the activated carbon to absorb caffeine to selectively remove caffeine, and removing a precipitate of insoluble components, said activated carbon, by filtration. 5. The packaged beverage according to claim 1, wherein said packaged beverage is prepared by adding a green tea extract to a beverage and wherein said green tea extract is prepared by a process comprising dissolving a solid caffeine-containing catechin composition in a mixed solution comprising ethanol and water in a ratio ranging from 9/1 to 1/9 by weight, wherein said ratio is the ratio of ethanol to water in the mixed solution, bringing the resultant solution into contact with activated carbon allowing the activated carbon and also acid clay or activated clay to absorb caffeine to selectively remove caffeine, and removing a precipitate of insoluble components, said activated carbon and also said acid clay or said activated clay, by filtration. 6. The packaged beverage according to claim 1, wherein said packaged beverage comprises a content of gallates in said non-polymer catechins of from 45 to 51.3 wt %. 7. The packaged beverage according to claim 1, wherein said packaged beverage comprises a weight ratio of said non-polymer catechins to caffeine of from 8.8 to 38.8. 8. The packaged beverage according to claim 1, wherein said packaged beverage comprises from 0.1 to 0.4 wt % of non-polymer catechins. 9. The packaged beverage according to claim 1, wherein said packaged beverage comprises from 0.11 to 0.3 wt % of non-polymer catechins. 10. The packaged beverage according to claim 1, wherein said packaged beverage comprises from 0.12 to 0.3 wt % of non-polymer catechins. 11. The packaged beverage according to claim 1, wherein said packaged beverage has a weight ratio of said non-polymer catechins to (sucrose+glucose) of from 2 to 10. 12. The packaged beverage according to claim 1, wherein said packaged beverage has a weight ratio of said non-polymer catechins to (sucrose+glucose) of from 2 to 8. 13. The packaged beverage according to claim 1, wherein said packaged beverage has a weight ratio of said non-polymer catechins to (sucrose+glucose) of from 3 to 7. 14. The packaged beverage according to claim 1, further comprising a bitterness suppressor. 15. The packaged beverage according to claim 14, wherein the bitterness suppressor is a cyclodextrin and is present in an amount ranging from 0.01 to 0.5 wt %. 16. The packaged beverage according to claim 1, wherein the pH of the beverage ranges from 2 to 7 at 25° C. 17. The packaged beverage according to claim 1, further comprising one or more additives selected from the group consisting of an antioxidants, a flavor, an ester, an organic acid, an organic acid salt, an inorganic acid, an inorganic salt, a colorant, an emulsifier, a preservative, a seasoning agent, a sweetener, a sour seasoning, a fruit extract, a vegetable extract, a flower honey extract, a pH regulator and a quality stabilizer. 18. The packaged beverage according to claim 1, further comprising at least one sweetener or at least one sour seasoning, wherein said sweetener is selected from the group consisting of sugar, glucose, fructose, isomerized syrup, glycyrrhizin, stevia, aspartame, fructooligosaccharide, and galactooligosaccharide,said sour seasoning is selected from the group consisting of a fruit juice, citric acid, tartaric acid, malic acid, lactic acid, fumaric acid, and phosphoric acid, andsaid at least one sweetener or at least one sour seasoning is in an amount of from 0.01 to 0.5 wt %.
