Explore how sake is made, what those bottle labels mean, whether to drink it hot or cold, and why it belongs alongside much more than Japanese food
For a drink made largely from rice, water and koji, sake can feel surprisingly complicated.
Pick up a bottle and you are confronted with words such as junmai, ginjo, daiginjo, kimoto, yamahai, nigori and genshu. Then comes another question at the table: hot or cold? And if there is no sushi involved, should you even be drinking sake in the first place?
At Sake Reimagined Vol. 2, held at TAX in Bangkok on 30 August 2026, The Sake Room’s certified sake instructor and sommelier Teru set out to make the category a little less intimidating. The session moved from fundamental sake knowledge and brewing techniques to tastings, food pairing and eventually the use of sake in cocktails.
It was a useful reminder that learning about sake does not have to mean memorizing a dictionary of Japanese terminology. A few fundamentals can dramatically change how you choose, drink and enjoy it.
First Things First: What Is Sake?
One common misconception is that sake is “rice wine.” It is an understandable shorthand, but its production is actually quite different from wine.
Sake is a brewed, fermented alcoholic beverage whose principal ingredients are rice, water and koji. It is not a distilled spirit. Under Japan's geographical indication rules, “Nihonshu” specifically refers to sake made in Japan using Japanese rice and rice koji.
The magic ingredient is koji.
Koji is steamed rice cultivated with the mold Aspergillus oryzae. Its enzymes convert the starch in rice into fermentable sugars. Yeast then converts those sugars into alcohol. In sake brewing, those two processes happen simultaneously in the same mash, a technique known as multiple parallel fermentation.
At TAX, the process was broken down into an approachable sequence: rice is polished, washed and soaked, steamed, partially turned into koji, combined with yeast and other ingredients to create the fermentation starter and mash, fermented, then pressed and prepared for maturation and bottling.
Rice polishing is particularly important. The percentage printed on a sake label refers to how much of the rice grain remains after polishing, not how much has been removed. A 40% polishing ratio, for example, means 40% remains. Removing the grain's outer layers can help brewers achieve different aroma and flavor profiles, although greater polishing should not automatically be read as “better sake.”
Sake Words Worth Knowing
You do not need to decode every Japanese word on the bottle. Knowing a handful can give you useful clues.
Junmai means the sake is made with rice, koji and water, without added neutral brewing alcohol.
Ginjo and daiginjo indicate particular premium sake classifications associated with highly polished rice and specific brewing methods.
Daiginjo uses rice polished more extensively than ginjo and is often associated with refined, aromatic styles.
Then there are terms describing how a sake is made or presented rather than simply its grade. Kimoto and yamahai refer to traditional approaches to creating the fermentation starter using naturally developing lactic acid bacteria, often producing sake with more pronounced acidity, umami and complexity.
Nigori refers to cloudy sake containing fine rice particles, while genshu indicates sake bottled without the usual dilution with water. Nama means unpasteurized sake.
But labels only tell you so much.
One of the most practical frameworks introduced during Sake Reimagined was to think about sake through four broad flavor directions: fruity and floral; light and clean; umami-rich; and aged or smoky.
For the casual drinker, those descriptions may ultimately be more helpful than chasing classifications. Asking a sommelier or bartender for something “fruity and aromatic” or “rich and umami-forward” immediately gives them somewhere to start.
Hot or Cold? There Is No Single Rule
The image of a small ceramic flask of steaming sake remains familiar, as does the assumption that premium sake should always be chilled.
Neither tells the whole story.
Sake has an unusually wide serving-temperature range, and temperature is effectively another tool for changing the drinking experience. The Japan Sake and Shochu Makers Association broadly divides serving temperatures into chilled at around 8–15°C, room temperature at 15–25°C and warmed at around 40–50°C.
Chilling generally emphasizes freshness and can preserve fruity aromas, while reducing the perception of sweetness and umami. Warming can make sweetness and umami more apparent, broaden the flavor and bring forward cereal-like aromas.
So, should sake be served hot or cold? The better answer is: it depends on the sake and what you are eating.
A delicate, highly aromatic sake might shine chilled, while an earthy, umami-rich style can reveal a completely different personality when warmed. Experimenting with the same bottle at different temperatures can be part of the fun rather than a breach of sake etiquette.
Sake Doesn't Need Sushi
Perhaps the most useful takeaway from the TAX session was what happened when the sake reached the dining table.
The tasting did not stay within the predictable territory of sashimi and sushi. Pairings prepared by Kenji's Lab included peach and ham with burrata and rocket salad, mixed seafood carpaccio, smoked duck with spicy-sweet sauce, Korean-style roast pork and unagi bo-sushi.
That variety demonstrates something increasingly important about contemporary sake culture: sake is Japanese, but sake pairing does not have to be.
One reason is umami. Sake contains amino acids, including glutamic acid, associated with umami. This can help sake complement the savory character of ingredients ranging from seafood and mushrooms to meat and fermented foods. Japan's sake industry association similarly notes that sake's umami and relatively broad flavor spectrum allow it to work with cuisines well beyond Japanese food, including cheese and charcuterie, salads and desserts.
The basic principles are not dramatically different from pairing wine. Match intensity with intensity, look for complementary aromas, or deliberately create contrast. Temperature adds another variable.
A richer sake can stand alongside richer food. Fruity aromatics can lift seafood. Acidity and a dry finish can refresh the palate after fatty meat. Earthier sake can find common ground with smoky, roasted or mushroom-driven dishes. In other words, there is little reason to put the sake bottle away just because dinner is Italian, Thai, Korean or French.
Five Sakes, Five Very Different Personalities
The Bangkok class made that diversity tangible through five styles.
Senkin Organic Nature from Tochigi, made using the kimoto method and wild yeast, brought yogurt, pear and lemon notes with mild effervescence.
Kamoshibito Kuheiji “Human,” an aromatic junmai daiginjo from Aichi, moved toward white flowers, pineapple, banana and melon.
Tengumai Yamahai Junmai from Ishikawa went in an earthier direction with mushroom, walnut, dried fruit and butterscotch.
Daishichi Yukishibori Nigori from Fukushima showed sake's cloudy, gently sparkling side, with white peach, pear and lactic notes.
Kamotsuru Taruzake from Hiroshima demonstrated another possibility altogether: sake aged briefly in cedar, giving it a distinctive woody aroma alongside hints of fruit and a dry, clean finish.
Taste those bottles side by side and the idea that “sake tastes like sake” quickly disappears.
The Best Way to Understand Sake? Drink More Curiously
The sake category can become technical very quickly, but it does not need to begin there.
Start with a few questions. Do you want something light or rich? Fruity or earthy? Clean or full of umami? Try it chilled, then let the temperature rise. Order it with something other than Japanese food. Pay attention to what changes.
That was ultimately the strength of Sake Reimagined. Rather than treating sake as something governed by intimidating rules, TAX and The Sake Room approached it as something to taste, compare and play with. The second half of the Bangkok session pushed the idea even further, taking sake behind the bar and exploring its application in cocktails.
Because once the terminology stops getting in the way, sake becomes a much more versatile proposition: a drink that can be floral or funky, sparkling or smoky, chilled or warm, poured with sashimi or roast pork. And knowing that may be the most useful sake lesson of all.
