RAK Porcelain Sake Cups & Bottles

The most common standard is 720 mL (24.346 oz) (known as a yongobin), roughly equivalent to 4 traditional Japanese go cups of 180 mL (6.086 oz) each. The other standard sake bottle is the isshobin, which holds 1.8 L (60.865 oz).

A 720-mL bottle typically yields 8–13 servings depending on cup size, while a 1.8-L bottle provides approximately 20–30 servings for larger groups.
