Fermented milk having a satisfactory level of hardness as well as smooth texture produced by deoxidizing (deaerating) a yogurt mix, subjecting the deoxidized (deaerated) product to an UHT processing, and then fermenting the resulting product. A process for producing a fermented milk includes a first deoxygenating step for decreasing oxygen concentration in a yogurt mix; a ultra high temperature sterilization step for heating the yogurt mix after the first deoxygenating step for longer than 1 second at higher than 110 degrees Celsius so as to sterilize the yogurt mix; and a fermentation step for fermenting the yogurt mix after the ultra high temperature sterilization step.
