A method of producing a drink contained in a container comprising steps of heating and thereby sterilizing a tea drink having pH of 4.6 or over and containing catechin in an amount of 30 mg % or over or an acidic drink having pH of less than 4.6 and thereafter maintaining the sterilized drink at a temperature within a range from 60° C. to 70° C. and, in the meanwhile, heating and thereby sterilizing and rinsing a container on at least its inner surface with heated water having a temperature within a range from 65° C. to 100° C., filling the drink in the sterilized container at a filling temperature within a range from 60° C. to 70° C. in an environment controlled space which is separated from an outside environment and in which filling and sealing apparatuses and an environment surrounding the filling and sealing apparatuses have been heated and thereby sterilized and rinsed with heated water having a temperature within a range from 65° C. to 100° C., and sealing the container filled with the drink and thereafter cooling the container to a normal temperature of 40° C. or below.
