Grades of Sake
A study guide to the grades of sake — futsu-shu versus premium, the eight special-designation grades, and the two axes of polishing ratio and added alcohol.
The wall of Japanese on a sake label looks forbidding until you realise it is mostly answering two questions, and only two. Is there added alcohol, or is it pure rice? And how far was the rice polished? Plot any premium sake on those two axes and its grade falls out automatically. There is no quality ranking hidden in the words — the grade is a recipe specification, a promise about ingredients and milling, not a score. A humble junmai can outshine a daiginjō; the grade only tells you how it was built.
Fix the two axes and the junmai/non-junmai split, and the eight premium grades stop being vocabulary to memorise and become a simple grid.
The one thing to fix first: two categories, then two axes
All sake is first either:
- Futsū-shu (普通酒, "ordinary sake") — everyday table sake, the majority of what Japan drinks, with no polishing requirement and freedom to add cheap distilled alcohol and other adjusts. Roughly 60% of production.
- Tokutei meishō-shu (特定名称酒, "special-designation sake") — premium sake, which must meet legal rules on rice grade, polishing and additions. This is where the eight grades live.
Within premium sake, two axes decide the grade:
- Added alcohol or not — a small, legal dose of distilled jōzō alcohol (capped at 10% of the rice weight) makes a sake non-junmai; adding none makes it junmai (純米, "pure rice"). Jōzō alcohol lifts aroma and lightens the body — it is a stylistic tool, not a cost-cutting one, at this level.
- How far the rice is polished — the seimai-buai, which climbs from honjōzō through ginjō to daiginjō.
The eight premium grades
Read this as a grid: the left column is the polishing rung; the two right columns are "with a touch of alcohol" versus "pure rice".
| Polishing | Non-junmai (added alcohol) | Junmai (pure rice) | Seimai-buai |
|---|---|---|---|
| Base | Honjōzō | Junmai | ≤70% / junmai: none required |
| "Special" | Tokubetsu honjōzō | Tokubetsu junmai | ≤60% or a special method |
| Ginjō | Ginjō | Junmai ginjō | ≤60% |
| Daiginjō | Daiginjō | Junmai daiginjō | ≤50% |
Four rungs × two columns = the eight special designations. A few things to hold onto:
- Junmai alone carries no minimum polishing (a 2004 rule change) — a junmai can be polished a little or a lot; the word only guarantees pure rice, no added alcohol.
- Ginjō means ≤60% polishing and a fragrant, cool-fermented style; daiginjō means ≤50% and the most delicate, aromatic sake of all.
- Tokubetsu ("special") means the brewer has either polished to ≤60% or used a special method they can justify — a flexible label for a standout base sake.
Key facts
| Two categories | Futsū-shu (ordinary) and tokutei meishō-shu (premium) |
| Premium grades | Eight special designations |
| Axis 1 | Added jōzō alcohol (non-junmai) vs none (junmai) |
| Axis 2 | Polishing: honjōzō ≤70%, ginjō ≤60%, daiginjō ≤50% |
| Junmai polishing | No legal minimum (since 2004) |
| Grade ≠ quality | It's a recipe spec, not a score |
Junmai versus alcohol-added, briefly
The junmai/non-junmai line causes the most confusion, so it is worth stating plainly. Adding a small measure of distilled alcohol near the end of fermentation was once a wartime way to stretch volume, and it still is in cheap futsū-shu. But at premium level it is a stylistic choice: the alcohol pulls aromatic compounds out of the mash and gives a lighter, cleaner, more fragrant sake. That is exactly why many prize-winning daiginjō are not junmai. Junmai styles, with nothing but rice, tend to be fuller, rounder and more savoury. Neither is better; they are different targets.

The grades in the glass
| Grade | Typical character |
|---|---|
| Honjōzō | Light, clean, mild; excellent warmed |
| Junmai | Full, round, savoury, rice-forward; food-friendly, versatile temperature |
| Ginjō / junmai ginjō | Fragrant and fruity — apple, pear, melon; best chilled |
| Daiginjō / junmai daiginjō | The most delicate and perfumed; silky, precise; serve well chilled |
The pattern: more polishing → more fragrance and finesse, less rice character; and added alcohol → lighter and more aromatic, junmai → fuller and more savoury. Serving temperature tracks this — the fragrant ginjō grades are chilled to protect their aromas, while honjōzō and junmai can take gentle warming (storing & serving).
Is more polishing always better?
No — and this is the trap the grade system sets. Polishing to 50% or 35% strips away protein and fat, yes, but also much of the rice's own character, leaving a very clean, very fragrant, sometimes hollow sake. A skilled junmai polished to only 65% can be more complex, textured and interesting than a daiginjō polished to the bone. High polishing is expensive and impressive, but it buys delicacy, not automatically quality. Judge the sake, not the ratio.
Reading the grade beside the other terms
The grade is only one clause in the label sentence. A bottle might read junmai ginjō muroka nama genshu — that is: pure rice, ≤60% polished and fragrant (grade), not charcoal-filtered (muroka), unpasteurised (nama) and undiluted (genshu). The grade tells you the recipe backbone; the labelling terms tell you the finishing choices layered on top.
Classic exam questions
- What are the two categories of sake? — futsū-shu (ordinary) and tokutei meishō-shu (special-designation / premium).
- How many special-designation grades are there? — eight.
- What is the difference between ginjō and junmai ginjō? — both are polished to ≤60%; junmai ginjō has no added alcohol, ginjō has a small amount.
- What polishing does daiginjō require? — 50% or less.
- Does junmai have a minimum polishing ratio? — no (since 2004); it only guarantees pure rice with no added alcohol.
- Is a daiginjō always better than a junmai? — no; the grade is a recipe specification, not a quality score.
Two axes, eight grades, one grid — and the label stops being a wall of kanji and starts telling you exactly how the sake was built.
