A method of making a sweet rice drink(sikhye) with a grain of boiled rice by using nano-filtration is provided to produce the sweet rice drink which is clean and transparent while having original taste of sikhye, to prevent generation of gas through post-fermentation and to increase the storage time period of sikhye. To make the titled sweet rice drink, a conventional sweet rice drink is subjected to nano filtration using a nanofiltration membrane with a molecular weight cut-off of 30 to 10,000Da. The nano-filtration is performed at an operating pressure(gauge pressure) of 0.5 to 50Mpa and 5 to 80deg.C. For an example, 4,000g malt powder is soaked in 28,000g water and fermented with 4,000g boiled rice and 20g sugar for 5hr to give a sweet rice drink which is subjected to nano filtration.
