A method of forming a ready-to-drink coffee product includes contacting a first ground coffee composition with water having a temperature of less than 10° C. for at least 16 hours to form a first cold brew concentrate; mixing the cold brew concentrate and water to form a mixture; heating the mixture to a temperature of less than 100° C. for less than 1 minute to form a pre-fill coffee composition; pouring the pre-fill coffee composition into a cavity; concurrent to pouring, increasing a temperature of the pre-fill coffee composition to at least 82.2° C. and holding the pre-fill coffee composition at the temperature of at least 82.2° C. for at least 30 seconds to form a filled coffee composition; and cooling the filled coffee composition to ambient temperature within the cavity to form the ready-to-drink coffee product. A ready-to-drink coffee product system is also disclosed.
