How much liquid does a Tobin contain?

A Tobin, which is a traditional Japanese sake barrel or container, typically has a capacity of 18 liters. This size is commonly used in the sake industry for storing and serving sake. Understanding the measurement of a Tobin is significant because it reflects not only the actual volume of sake but also the cultural practices surrounding sake consumption and storage in Japan. The use of specific volumes, such as 18 liters, plays a role in the efficiency of brewing, distribution, and even ceremonial uses of sake.

It's also worth noting that while other options like 1 liter, 5 liters, and 10 liters are valid volume measurements for other types of containers, they do not accurately represent the standard size of a Tobin in traditional sake culture, which is well-established at 18 liters.
