But with sake, there is no codified standard drinking vessel. There are many different forms in play.
Here are a few examples:
Pottery is popular as well.
Footed glassware is also widely used.
Several sake vessels are white with dark blue markings on the bottom. This is for a practical reason: A sake that is meant to be clear (non-nigori) will sometimes turn cloudy if it has slightly spoiled. The white cups with the blue circles are often used by sake judges, and the blue circles help them to detect clarity imperfections in sake, and potentially determine if a sake has begun to spoil.
