매화수 Maehwasu is a one kind of Korean liquor made from ripened green plums and contains alcohol. It tastes very sweet and I like it. I tried to drink maehwasu in one of the Korean restaurant in Insadong, it was my first time to drink it. Sweet taste of maehwasu is very suitable for women ^^
I enjoyed maehwasu together with samgyetang (a chicken soup) and I think both of them are really great to consume in the summer.
