Ochoko and Guinomi Sake Cups: What's the Difference? Why Use Them?

Nowadays, the whole world raves about Japanese sake! But not everyone knows the ins and outs of sake cups like “ochoko” and “guinomi.” This can be troublesome for people buying drinking sets online. How do the two kinds of cups differ and which one should you go with? Also, is it true that sake tastes differently depending on the cup you drink it from? In this article, we’ll answer these questions and more while introducing our recommended sake drinking sets, so make sure to read to the end!

What’s the Difference Between Ochoko and Guinomi Drinking Cups?

It’s easy to confuse ochoko and guinomi at first glance, especially if you’re shopping online where many cups almost look identical. The main difference between the two is their size and therefore volume. However, there is no law or official definition that restricts each type to however many centimeters. When distinguishing the two cups, we mainly look at whether their contents can be drunk in one gulp.

Ochoko (can be emptied in one gulp): 20 – 50 mL
Guinomi (can’t be emptied in one gulp): 40 – 200 mL

It’s often said that the easiest amount for an adult man to drink in one gulp is about 20 mL, so cups that can hold 20-30 mL of sake are classified as "ochoko." Cups with a volume of 40 mL or more can be called both "ochoko" and "guinomi" depending on the maker. There is no well-defined difference between the two.

What Is an Ochoko Cup?

The “o” in “ochoko” (お猪口) is a Japanese honorific prefix while “choko” means “a little bit.” The word is meant to describe a small cup that you can empty in one gulp.

If you enjoy a little sake at dinner, there is nothing better than a pitcher of sake with an ochoko cup!

What Is a Guinomi Cup?

A "guinomi" is a sake cup larger than an ochoko but smaller than a regular rice bowl. Some say that the name comes from “guitto tsukande nomu” (“to drink down in a gulp”) or “guigui nomu” (“to drink fast”), but that’s just a theory and the real etymology of “guinomi” is unknown. In any case, a guinomi cup must be bigger than an ochoko and take about two gulps to empty.

How Do Cups Affect the Taste of Sake?

How Does an Ochoko Cup Affect the Taste of Sake?

Ochoko cups need to be small enough to empty in one gulp, and because they hold such a small amount, they guarantee that your drink won’t become warm when serving cold sake.

How Does a Guinomi Cup Affect the Taste of Sake?

If you serve cold sake in a guinomi cup to someone who’s a slow drinker, their drink might become warm.

What Else Can Affect the Taste of Sake?

Another thing that can affect the taste of sake is the material that the cups are made from. For example, if you’re serving ginjo*, daiginjo*, or some other sake with a fruity aroma and delicate flavor, you’ll want to use glass cups. However, with full-bodied, strong-flavored drinks like junmaishu* or yamahai jikomi*, you should go with porcelain.

You can have fun experimenting with different combinations of cups to match people’s preferences, drinking speeds, and the temperature of sake. Though ochoko cups, which are available in many different varieties, tend to only be made for sake due to their small size, the larger guinomi are sometimes also used to serve shochu or even whiskey.

*Trivia: What Is Ginjo, Daiginjo, Junmaishu, and Yamahai Jikomi?

●Ginjo and Daiginjo
Sake is made entirely from polished rice grown especially for sake production. If 60% or less of the rice grain remains after polishing (milling), then the resulting drink will be defined as "ginjo." If this number is 50% or less, then it’ll become "daiginjo." That’s why daiginjo is generally more expensive than other varieties, and because it’s made from well-polished rice, it has a smoother and clearer taste.

This type of sake is made from rice, koji (malted rice), and water, with no added brewing alcohol, resulting in a rich, well-rounded, and often full-bodied flavor.

●Yamahai Jikomi
In sake production, there are two main types of “shubo” (yeast mash cultivated from steamed rice, koji malt, and water): the fast-brewing kind and the traditional “kimoto” kind. Yamahai Jikomi is made from the latter, but forgoes the process of “yamaoroshi,” which sees steamed rice placed in a large barrel or tank and mashed with a paddle. Because this process was so labor-intensive and thanks to studies proving no difference in taste between mashed and un-mashed rice, a lot of brewers switched to un-mashed Yamahai Jikomi production.

Recommended Ochoko Cups

As ochoko cups are small and allow sake to be drunk in one gulp, we recommend buying them in sets with “tokkuri” pitchers or “katakuchi” servers. Katakuchi are different from tokkuri, as they are flat and have spouts on one side that make it easier to pour alcohol.
