Reading a sake label: bottle size, alcohol and rice polishing
A sake bottle can carry several numbers that answer different questions. Before choosing a glass at an izakaya, read the words beside each number. Here is a fictional example for practice, not a product recommendation or a claim about a bar's stock.
Three numbers, three meanings
Imagine a label showing 内容量 720ml / アルコール分 15% / 精米歩合 60%.
- 内容量 720ml describes the liquid volume in the bottle. It does not tell you how much the bar pours into one glass.
- アルコール分 15% is alcohol by volume, often abbreviated ABV. Read this field when comparing alcohol concentration.
- 精米歩合 60% is the proportion of the rice's original weight remaining after polishing: in this example, 40% was removed. It is not a 60% alcohol drink.
These distinctions follow the Japan Sake and Shochu Makers Association's label guide. The National Research Institute of Brewing glossary is a further reference for unfamiliar label terms.
Turn the label into an order
Point to the menu item and ask この一杯は何mlですか? — How many millilitres are in this serving? Then confirm its price. A bottle specification and a menu serving are separate pieces of information; do not calculate the bill from the bottle size alone.
If comparing two drinks, write down the serving volume and price for each, keeping the ABV in a separate column. If staff cannot confirm a quantity, leave it unknown rather than treating a photograph of the glass as a measurement.
What the numbers leave unanswered
Do not use the polishing figure alone as a score for which sake you will enjoy. Tell staff what you are looking for and ask about the specific bottle. For broader terminology, see Japanese alcohol types; for ordering phrases, see ordering at an izakaya.
Does 720ml mean I must order a whole bottle? The label does not establish the bar's sales format. Ask whether that menu item is sold by the glass or bottle.
