How to Read a Sake Label: Junmai, Ginjo, Daiginjo

A sake label looks like a wall of vocabulary. Junmai, ginjo, daiginjo, honjozo, nama, genshu, a number with a percent sign, sometimes a number with a plus or minus in front of it. It reads like a code because it is a code — and the good news is that it is a small one. Almost the entire classification system comes out of two questions.

Learn those two questions and the rest of the label stops being intimidating and starts being useful.

Question one: was distilled alcohol added?

Some sake is made from nothing but rice, water, koji and yeast. Some has a small measured amount of distilled alcohol added late in the process.

If nothing was added, the label says junmai — literally “pure rice”. If something was added, it does not.

Now, the important correction, because this trips everyone up: added alcohol is not a cheapening trick. It once was, in the lean postwar years when it was used to stretch volume, and the reputation stuck. In good modern brewing it is a deliberate technique — alcohol pulls aromatic compounds out of the mash that water will not, so a small addition can make a sake lighter, drier and more fragrant. Plenty of superb, expensive sake has it. Plenty of dull sake does not.

Question two: how much rice was polished away?

A grain of rice has fat, protein and minerals concentrated towards the outside and clean starch at the core. Those outer compounds create heavier, earthier, sometimes coarser flavours. Milling them off leaves a purer starch to ferment.

The number on the label is the seimaibuai, and here is the catch that confuses people: it tells you how much rice is left, not how much was removed. So 60 percent means forty percent of every grain was milled away. Lower number, more polishing.

The thresholds are set by Japan’s labelling rules:

• Ginjo — 60 percent or less remaining, plus a slow, cool, painstaking fermentation the rules call ginjo-style brewing.
• Daiginjo — 50 percent or less remaining. Half the grain, gone.
• Honjozo — 70 percent or less, with a limited alcohol addition.
• Junmai — no added alcohol. Since a rule change in 2004 it carries no minimum polishing requirement of its own, which is why you now see junmai at every level of milling.

Stack the two questions and you get the whole grid. Junmai ginjo is pure rice, polished to 60 or below. Junmai daiginjo is pure rice, polished to 50 or below. Daiginjo on its own means polished to 50 or below with a little alcohol added. Sake with no designation at all is futsushu, ordinary sake — the everyday category, which is not an insult.

The myth worth killing

More polishing does not mean better sake. It means different sake.

Heavy milling gives you cleanliness, delicacy and aromatic lift. It also strips out body, savouriness and grip. A daiginjo can be gorgeous and it can also be so polite it has nothing to say next to a plate of grilled lamb. A humbler junmai often has far more to give food, which matters a great deal when the food in question has been over an open charcoal grill, as everything on our menu has.

Price follows polishing because polishing is expensive — it takes time and it destroys raw material. Price does not follow deliciousness nearly so reliably.

The other words on the label

Once the grid makes sense, the extra terms are just modifiers, and each one tells you something concrete:

• Nama — unpasteurised. Fresher, livelier, sometimes faintly wild. Needs cold storage.
• Nigori — coarsely filtered, so it arrives cloudy. Usually softer and sweeter.
• Genshu — undiluted, so noticeably stronger than the usual mid-teens.
• Muroka — not charcoal-filtered, so more colour and more character left in.
• Koshu — deliberately aged. Amber, nutty, dried-fruit flavours, a long way from the fresh-and-floral idea of sake.
• Kimoto and yamahai — older, slower starter methods that build acidity and a savoury, sometimes gamey depth.
• Nihonshu-do — the sake meter value. Positive numbers lean dry, negative lean sweet. Treat it as a hint, not a verdict, because acidity changes how sweetness reads.

Now read our list, which does not contain the whole grid

This is the honest part, and it is more instructive than a perfect textbook list would be. We keep five sakes at Hamilton Road — a restaurant list, not a specialist bar’s — and reading it as a label exercise shows you how real lists behave.

• A junmai ginjo that is snow-aged, described on our list as crisp and pure with a gentle aroma and quiet strength. Two designation words plus a maturation method that is not part of the grid at all.
• A second junmai ginjo, this one with lush tropical fruit and pineapple notes. Same two words, completely different drink — which is the single best argument that the designation is a starting point and not a description.
• A matcha junmai, which our list calls a junmai and matcha fusion: earthy, creamy, bittersweet. Worth flagging that once something is added for flavour, a bottle steps outside the strict designation system, whatever the name on the front says. It is also the sake that turns up in our Matcha-misu dessert and in the Matcha Milk cocktail.
• A sparkling sake in a small bottle — peachy, playful, and a category the junmai-ginjo-daiginjo ladder does not really cover.
• An amber, nutty, fig-toned sake made in an Edo-era style. That colour and those flavours are the aged register described above, and it is the one bottle here that most rewards a little warmth.

There is no daiginjo on our list, and no honjozo. That is not an oversight, it is what a five-bottle restaurant list looks like when you choose for range rather than for prestige. We would rather have five bottles that do five different jobs alongside charcoal food than five variations on one idea.

We also cannot quote you a price for any of them here, because our menus do not print drinks prices at all. Ask at the table.

Or, genuinely, just ask

All of this is useful, and none of it is required. The fastest route to the right bottle has always been to tell someone what you are eating and roughly what you like, and let them point. Our floor team does this every night and nobody has ever been made to feel small for asking what junmai means.

If you would rather arrive knowing, the companion pieces are how to drink sake for the temperature and vessel side of things, and sake versus shochu for the other Japanese bottle on the same menu page — with shochu versus soju if the Korean green bottle is also on your mind. The format all of this belongs to is set out in our izakaya guide, and if you want to know where else in town does it properly, there is our honest shortlist and the late-night options.

One practical line before you book: we serve pork and a full bar, so we are not halal — that and the other common questions are in our FAQ.

The list itself is on our wine and sake page, the food it is meant to sit beside is on the main menu, and the room is in the gallery. We are at 29 Hamilton Road, Singapore 209198, Tuesday to Sunday from 5pm to 11pm. Book a table and we will happily talk you through all five.
