Speciality Styles
A study guide to sake's speciality styles — nigori, nama-zake, sparkling, taru-zake, kijoshu and koshu — and the production choices that create each one.
Beyond the eight grades sits a set of speciality styles — sakes defined not by how far the rice was polished but by a single distinctive production choice: leaving the sake cloudy, skipping pasteurisation, trapping bubbles, resting it in cedar, ageing it for years, or brewing it with sake in place of water. Each is a memorable, often crowd-pleasing style, and each is a clean illustration of one point in the process being pushed in an unusual direction.
Fix the idea that a speciality style is one deliberate deviation from standard sake, and the group organises itself: each style below is "normal sake, except for this".
The one thing to fix first: one choice defines each style
| Style | The defining choice |
|---|---|
| Nigori (にごり) | Pressed through a coarse filter, so rice sediment stays — cloudy |
| Nama-zake (生酒) | Not pasteurised — fresh, lively, kept cold |
| Sparkling (発泡) | Carbon dioxide trapped — bottle-fermented or injected |
| Taru-zake (樽酒) | Rested in cedar (sugi) casks — woody and fragrant |
| Kijōshu (貴醸酒) | Brewed with sake instead of water — sweet and rich |
| Koshu (古酒) | Deliberately aged — amber, honeyed, savoury |
Everything else — grade, rice, polishing — can vary underneath; the speciality name flags the one thing that makes it unusual.
The styles, in brief
- Nigori is coarse-filtered rather than clear-pressed, so fine rice particles remain and the sake pours milky. It is usually sweet and creamy, sometimes lightly fizzy, and is the classic "gateway" sake. Give the bottle a gentle roll to mix the sediment.
- Nama-zake skips pasteurisation entirely, keeping a fresh, zippy, sometimes slightly spritzy character. The trade-off is fragility: it must be refrigerated and drunk young or it goes "off condition".
- Sparkling sake traps CO₂, either by a second fermentation in the bottle (the finer, Champagne-like route) or by carbonation. Styles run from delicate and dry to sweet, cloudy and low-alcohol — an increasingly popular aperitif.
- Taru-zake is matured in casks of Japanese cedar (sugi), which lends a fragrant, resinous, woody lift. It is traditionally the sake broken open at celebrations (kagami-biraki).
- Kijōshu replaces some of the brewing water in the final mash addition with finished sake, so the yeast leaves much of the sugar unfermented. The result is a sweet, viscous, dessert-style sake; the technique was developed by the National Research Institute of Brewing in 1973.
- Koshu is sake aged on purpose, often for years, turning deep amber with honeyed, nutty, sherried, savoury flavours — the opposite of sake's usual drink-it-young rule.
Key facts
| Nigori | Coarse-filtered, cloudy, usually sweet and creamy |
| Nama-zake | Unpasteurised; fresh, fragile, refrigerate |
| Sparkling | Bottle-fermented or carbonated |
| Taru-zake | Cedar-cask rested; woody, celebratory |
| Kijōshu | Sake used in place of water; sweet, rich |
| Koshu | Deliberately aged; amber, honeyed |
Where they sit against standard sake, briefly
Most speciality styles are simply a standard-sake process with one step altered: nigori changes the filter, nama removes a pasteurisation, taru adds a cask, kijōshu swaps an ingredient, and koshu extends the ageing. Only sparkling adds something genuinely new — a route to carbonation. Reading them this way keeps the group from feeling like a list to cram: each is one knob turned.

Nigori and sparkling — the sweet, fun end
Nigori ranges from lightly hazy to thick and porridge-like, and most versions lean sweet and creamy, which makes them a natural match for spice — think chilli-hot food, where the sweetness cools the heat (faults & food pairing). Serve well chilled; roll the bottle to redistribute the settled rice before pouring.
Sparkling sake is the fastest-growing speciality category. The bottle-fermented style is drier, finer-beaded and more serious; the carbonated style is often sweeter, cloudier and lower in alcohol (sometimes 5–8%), aimed squarely at the aperitif and celebration market. Both want to be very cold.
Nama-zake and the autumn release
Nama-zake's freshness is its whole appeal, but unpasteurised sake keeps changing in the bottle and can develop a rough, off "nama-hine" character if it warms up — so the cold chain matters. A special seasonal case is hiyaoroshi: sake pasteurised once in spring, rested over summer, then shipped in autumn without a second pasteurisation — mellow, rounded, and tied to the season.
Koshu and kijōshu — sake for the cheese board
Koshu and kijōshu are sake's answer to dessert and fortified wine. Koshu's honeyed, nutty, umami-laden depth stands up to hard cheese, dried fruit and rich, savoury dishes; it is often served at room temperature or gently warmed to open the aromatics. Kijōshu's sweet viscosity makes it a small-glass dessert sake, lovely with blue cheese or chocolate, and best served cool.
Serving the speciality styles
| Style | Serve | Good with |
|---|---|---|
| Nigori | Well chilled | Spicy food, dessert |
| Sparkling | Very cold | Aperitif, celebration |
| Nama-zake | Cold | Fresh, delicate dishes |
| Taru-zake | Cool to room temp | Celebration, grilled food |
| Kijōshu | Cool | Blue cheese, chocolate, dessert |
| Koshu | Room temp or warmed | Hard cheese, rich savoury dishes |
Classic exam questions
- What makes nigori-zake cloudy? — it is pressed through a coarse filter, leaving rice sediment.
- What is nama-zake, and how must it be stored? — unpasteurised sake; keep it refrigerated and drink it young.
- Name the two ways sparkling sake gets its bubbles. — a second fermentation in the bottle, or carbonation.
- What wood is used for taru-zake? — Japanese cedar (sugi).
- How is kijōshu made distinctive? — sake is used in place of some of the brewing water, leaving it sweet and rich.
- What is koshu? — sake deliberately aged, developing amber colour and honeyed, savoury flavours.
Each speciality style is standard sake with one knob turned hard — cloudy, raw, fizzy, woody, sweet or aged — which is exactly why they are the easiest sakes to remember and to love.
