Sake, briefly explained
Sake (or more precisely nihonshu, since “sake” in Japanese just means alcohol in general) is brewed from rice, water, koji mold, and yeast. Despite looking like vodka, it’s closer in spirit to wine or beer—a fermented, not distilled, drink usually at around 15–16% ABV. That’s a little stronger than most wines but nowhere near spirits, and it pairs beautifully with fish, shellfish, tofu, and pretty much everything on a Japanese table. Once you start thinking of it as “rice wine with its own traditions” rather than “some kind of Asian liquor,” a lot of the service customs start to make more sense.
Grades are the other thing worth knowing before you order. The rough ladder runs futsushu (regular table sake) → honjozo → junmai → ginjo → daiginjo. Honjozo has a little added brewer’s alcohol, junmai has none, and ginjo and daiginjo are defined by how far the rice is polished (polished down to 60% and 50% or less of the original grain). Futsushu is everyday drinking sake and often served warm. Junmai is pure rice sake, often with fuller, rounder flavors. Ginjo and daiginjo are the premium tier—light, aromatic, floral, and usually served chilled so those delicate aromas survive. You don’t need to memorize any of this, but even knowing the ladder exists helps you pick something that matches the moment.
Then there’s temperature, which is maybe the most fun part of sake service. The same drink can be served chilled (reishu), at room temperature (jouon), gently warmed (nurukan, around 40°C / 104°F), or properly hot (atsukan, around 50°C / 122°F). Warm sake isn’t a budget move—it’s a whole different experience, softer and rounder, particularly lovely on a cold night with hearty food. Premium grades usually stay cold to protect their aromas, while more rustic grades bloom when heated. The tokkuri-and-ochoko ritual—flask and tiny cup, pouring for each other, slowly working through a flask that often holds about 180ml—is designed to make a fairly small amount of alcohol feel like a long, warm evening. Lean into it and it stops feeling like a set of rules and starts feeling like one of the nicest ways to drink anywhere in the world.
Short version: pour for others, ask the staff what temperature to try, and say “sumimasen, mou ippon” when you want another flask.
A few “nice to know” extras
- It creeps up on you — Sake is usually around 15–16% ABV, a bit above most wine, but refills come quickly and the ochoko is so small it’s easy to lose count. A tokkuri or two can sneak up on you faster than the same volume of wine would. Pace yourself and drink water alongside.
- “Nihonshu” vs “sake” — In Japanese, sake just means alcohol in general, so if you want to be specific about Japanese rice wine, the word is nihonshu. Ordering “sake” in Japan usually still works, but nihonshu is the precise term.
- Explore by prefecture — Some izakayas organize their sake menu by region—Niigata, Akita, Hiroshima, and so on—each with its own style and character. If you’re curious, ask the staff for a recommendation from a specific prefecture; it’s a great way to make the evening feel like a little tasting tour.
- Shochu is not sake — Shochu looks similar but is actually a distilled spirit (commonly around 25% ABV), often served mixed with hot water, cold water, or on the rocks. It plays by different rules and has its own etiquette—don’t assume a shochu order gets you sake or vice versa.
- Food pairing is easy — Sake is very food-friendly. It goes well with sashimi, grilled fish, tempura, tofu dishes, yakitori, and most Japanese food in general, so you can order confidently without overthinking.
