There are different traditional methods for the sake of representation. While drinking sake in a professional way, you use a sake set. A traditional sake set includes a porcelain flask, known as tokkuri, with small cups called Choko or sakazuki.
You can also serve cold sake in traditional wine glasses. In important Japanese events like holidays, weddings, birthdays, and anniversaries sake is placed in a masu. Masu is a standard cedar wood box that presents the traditionally brewed sake, as in old times, it was brewed in wood casks.
