Sake glossary

Sweet-style sake, the flip side of karakuchi (dry). Treat it as a compass rather than a map: perceived sweetness also depends on acidity, serving temperature, alcohol, and other factors. In addition, it's a pretty rare designation on labels, with many sweet styles (ex. Akabu) making no mention of "amakuchi." When you do see it, you're usually looking at a more old school brewery rather than a modern one, where sweetness is almost a given.

The "first run" juice that trickles out of the sake press before any pressure is applied to the mash. Lively, slightly cloudy, textural, rich in CO2, brash and fresh. In a culture where subtlety is often celebrated, arabashiri can be considered a lower quality press fraction, while the center cut (nakadori/nakagumi) is cleaner, denser, and smoother, with a more "pure" expression of the sake. Still, arabashiri has its fans (like us!!) and many breweries will bottle and sell it separately as a treat. Rare to find in the US.

The oldest yeast-starter method still in use, developed by temple brewers in Nara some 6-800 years ago. Soured naturally with raw rice and warm water, it gives sake a wild, tangy, lactic & acetic flavor. Modern adaptations (ex. Tsuji Honten, Gozenshu brand) pasteurize the soured water before adding yeast + completing the main ferment, resulting in a much softer, less acetic, sour style. Look also for mizumoto, which is very similar in style and method but lacks the regional affiliation with Nara's Bodaisen temple.

The most polished class of sake: each rice grain milled to 50% or less of its original size, then brewed slow and cold, adding distilled alcohol right before pressing. This alcohol addition (limited to 10% of the weight of the rice, though less is typically used) accomplishes three goals. First, the distilled alcohol will temporarily boost the ABV of the mash, allowing more alcohol-soluble aromatic esters to dissolve into the liquid phase from the rice solids. Second, the dilution (functionally) of the junmai daiginjo base sake makes it drier and lighter. Third, we see improved precision and clarity in the aromatic profile: less "aromatic noise" due to the combined effect of overall dilution + the enhanced concentration of those alcohol-soluble aromatic esters that tend to loft from the glass more readily. Daiginjo brewing demands the utmost technique, labor, and skill of the toji, master brewer. This class is considered to require the most technical skill in execution, and it's where most brewers compete, submitting their best daiginjo to professional competitions every year. Expect aroma over muscle: melon, flowers, snowmelt on a mountain, a perfectly slick and clean expression.

Sake's rustic ancestor: a thick, chunky, (often) gently fizzy rice brew that never gets pressed at all. As nutritious as it is lightly alcoholic, typically between 6-15%. Doburoku is farmhouse sake, and a great way to start playing with home brewing. It's very rare in the US (and in Japan, really) as it was outlawed in Japan for nearly a century for being untaxable hooch, essentially.

"Ordinary sake"-- the everyday table sake that makes up most of what Japan actually drinks, though its popularity is waning. No polishing requirements, no premium designation, up to 50% of the weight of rice can be added as distilled alcohol & additives like sweeteners, amino acids, flavorings, are permitted. Much like table wine and cheap beer, there's great, good, decent and bad, and the key is knowing which brands are better than others. Pretty much all futsushu is designed to be simple, balanced, and meant for everyday enjoyment-- without a ton of personality, complimentary with food, good at any temperature, durable and long lasting. Futsushu often has more regional/local character than other styles, because it's not valuable enough to be shipped to Tokyo & beyond.

An interesting and evolving category. Genshu means undiluted, or we could call it "cask-strength" sake. Genshu sake foregoes the usual water dilution before bottling, which is done to mellow out a 17-18% base sake to ~15%: softer flavor, more food friendly, better suited to casual drinking, more cost effective. As a result, genshu is historically associated with bold, powerful 17-19% brews. However, that convention is changing: in the last 5-10 years, we're seeing 12-13% sake classified as genshu. The reason for this is twofold: a sake diluted before the mash is pressed is considered genshu, even if that dilution happens seconds before pressing. Alternatively, a sake brewed--designed-- to land at 12% is a genshu too, so long as no water is added after it's pressed. The term doesn't have a lot of meaning these days, as we see genshu and non-genshu sake with comparable flavor concentrations. Your best bet is to check the ABV to know how punchy & boozy it's going to be.

A premium grade where the rice is polished to 60% remaining-- 40% of each rice grain is polished away-- then the sake is fermented cool to coax out fruity, floral aromas, before distilled alcohol is added right before pressing, to accomplish three goals. First, the distilled alcohol will temporarily boost the ABV of the mash, allowing more alcohol-soluble aromatic esters to dissolve into the liquid phase from the rice solids. Second, the dilution (functionally) of the junmai base sake makes it drier and lighter. Third, we see improved *precision* and *clarity* in the aromatic profile: less "aromatic noise" due to the combined effect of overall dilution + the enhanced concentration of those alcohol-soluble aromatic esters that tend to loft from the glass more readily. A well-made ginjo doesn't taste anything like the distilled alcohol that was used, and ginjo (like all aruten sake) requires incredible skill to pull off well. But a mediocre ginjo does taste a bit like distilled alcohol, with distracting notes of marshmallow and a slick, glycerine-like mouthfeel.

A workhorse sake rice from Niigata, named "five million koku" to celebrate the prefecture's record 1957 harvest. Cold-tolerant and high yielding, it's now grown throughout Honshu but particularly Tohoku & San'in. Tends to make clean, light, tidy sake in the crisp end of the spectrum.

Pasteurization. A quick, gentle heating (the word means "putting in fire") that stabilizes sake for travel and storage, killing bacteria, yeasts, and denaturing enzymes. Most sake gets pasteurized twice, once before storage and then again at bottling to be sure there's no risk of re-fermentation in bottle, which can result in unintended effervescence or flavors of bacterial contamination, like sour milk. A lot of premium sake will forego the double pasteurization, heating the sake directly in the bottle after pressing and dilution, so that it's safe to mature for the 6-12 months before shipping (thus no second pasteurizaton is needed). If you skip pasteurization entirely, you have (raw) namazake.

Fall seasonal release sake: brewed in winter, pasteurized once, rested through the summer, and bottled when the air turns cool. Hiyaoroshi literally refers to the equalization of temperatures in the brewery (cool) and outside. Rounder and more settled than its springtime siblings, fruit takes on more of a lightly baked or poached character and subtle notes of spice, marzipan + toast emerge from the maturation. Some breweries lean into this character and age longer, while others brew fresh sake and design autumnal character in their own way. We're seeing modern breweries buck the "hiyaoroshi" term and aging convention, using terms like "akiagari" or original branding instead.

A traditional style with a small, deliberate addition of brewer's alcohol before pressing — not to stretch the batch, but to lift aroma and lighten the body, making it more quaffable, crushable, more Pacifico Clara on a hot day. Honjozo sake also ages differently, slowly...the brewer's alcohol sublimates into the savory notes, bringing out milk chocolate, marmite, and creamy almond milk. We love honjozo warm, and the typically lower price point is nice, too.

A Japanese pub, the natural habitat of sake. Grilled things on sticks, karaage, oden, motsu-nabe, long conversations with fellow locals. Not all izakaya specialize in sake but some do, with their proprietors taking particular care to select their favorites from around the country or exclusively from home turf. Even when they don't specialize, an izakaya will often proudly pour a futsushu- table sake- from a nearby brewery, quietly repping a decades-long relationship of mutual support.

"Local sake" — small-production sake from regional breweries, made with local character rather than national ambitions. All sake was once jizake, but this term arose to distinguish small, local breweries from large breweries in Nada and Fushimi (such as Gekkeikan, Ozeki, and Hakushika). Just as these breweries reached their height, jizake became a trend, and even inspired regional tourism. Sunflower sake specializes in jizake.

"Pure rice" sake, made with rice, water, koji, yeast, and usually lactic acid. You'll often see junmai appended to other terms like ginjo or daiginjo, and when used in this compound way means that the sake has no added alcohol and only uses these simple ingredients (+ their derivatives). When you see the term on its own, "junmai" sake or junmaishu is more of an everyday style, fuller bodied, a bit more savory, usually less aromatic or those aromas lean toward grain, nuts, tea, rather than perfumey flowers & fruits. Modern junmai like Heiwa Shuzo's Kid brand lives somewhere in between classic old-school junmai and aromatic, light junmai ginjo.

One of the two "highest" grades of sake along with daiginjo. Junmai means "pure rice" = no distilled brewers' alcohol has been added. Legally, the rice must be polished to 50% or less of each grain remaining, brewed cold and slow, typically with aromatic yeasts but not always. Junmai daiginjo is usually more weighty and with a heavier aromatic profile compared to daiginjo (its alcohol added sibling). Junmai daiginjo is a showpiece: aromatic, silky, built for lightly chilled sipping or careful pairing designed to compliment the often intensely aromatic profile.

Ginjo's smooth, often fruity and floral character made under the junmai, pure-rice rule: nothing but rice, water, koji, and (optionally, but usually) yeast and lactic acid. A junmai ginjo-class sake must use rice polished to 60% or more (60% remaining/ 40% removed), a minimum of 15% koji, careful ginjozukuri-style brewing, and it can't have added alcohol (as non-junmai ginjo does) or additives like sweeteners & flavorings (that would make it futsushu). Junmai ginjo is a happy medium between fuller-bodied, satisfying and savory junmai and smooth, aromatic and elegant junmai daiginjo. Often great with food, great on its own, reflecting the brewery's philosophy and style. Note that not all junmai ginjo are fruity in profile: think of this class as being "fruit, smooth and delicate *for* this particular brewery". One brewery's junmai ginjo is another brewery's "we won't serve this!"

"Dry the cup!" — Japan's toast, conventionally recited at the beginning of festivities. Traditionally not a toast with glasses clinking, more of a glasses up situation.

Dry-style, literally "dry mouth," the opposite of amakuchi. A karakuchi sake finishes clean and crisp rather than sweet, which makes it a natural fit for salty and greasy food, or moreish drinking. Cho-karakuchi means extra dry, but even cho-karakuchi sake can sometimes drink softer or sweeter than you'd expect, because it's all about the crisp finish-- the mid palate can be mellow, chocolatey, or fruity even.

Kasu is a generic term for any residue left over after pressing a (food) product of its liquid. Thus, sake kasu is the pressed lees left behind after liquid sake is squeezed from the porridge-like fermenting mash. Far too delicious to waste, Japanese cooks use it for pickling, soups, marinades, pastry and even skincare. In the US, unfortunately sake kasu usually goes to livestock feed.

A luxurious style brewed with finished sake in place of some (or all) of the water, in other words, sake brewed with sake-- sake squared! Most kijoshu is sweet, dense, and honeyed, it originated as sake's answer to Sauternes when a brewery in Hiroshima (Hanahato) was pressed to devise a dessert sake for international diplomats in fine dining. Kijoshu is taking on new meaning these days however, particularly as urban consumers lean into sweeter, acidic, layered styles, and as famous breweries (Aramasa) earn international renown for their pairing-focused kijoshu. Expect something different from Gozenshu (layered, complex, delicate and balanced sweetness) vs. Hanahato (aged, sweet, madeira/good cream sherry.)

The old-school starter method: brewers cultivate wild lactic bacteria — originally by pounding the mash with long poles — instead of adding lactic acid. Slower and riskier, but it builds deep, savory, yogurt-tangy complexity.

Steamed rice inoculated and grown with Aspergillus oryzae, a friendly mold that converts rice starch into sugar so yeast can do its thing. The single most important ingredient in sake: "ichi koji, ni moto, san zukuri" means first koji, second moto (starter), third mash.

The percentage of a batch's rice that becomes koji, typically around 20%, though 15% is the legal minimum. A nerdy spec-sheet number, but it shapes how rich and sweet the fermentation runs. Some go high (Kirei Hachiku, 89%), others go all the way (Nanbu Bijin All-Koji, 100%), with umami, koji flavor, sweetness and acidity rising along with it.

Aged sake. Most sake is drunk young, but rested for years it turns amber and deep — think caramel, nuts, soy, dried fruit. A small, wonderful rabbit hole.

A sake brewery, also called a sakagura (sake-kura, the k turns into a g). The building, the business, and a bit of the soul, all in one word.

The brewery workers, literally "people of the kura," who steam rice before dawn, tend the koji room, and handle a thousand small tasks under the toji's direction. 90% of the job is cleaning, 100% is hard labor. An extremely difficult job but one touched by camaraderie, teamwork and a sense of accomplishment.

The square cedar box that began life as a rice measure and now moonlights as a festive sake cup. If someone overpours your glass until it overflows into a masu, that's hospitality, not clumsiness.

The main fermenting mash — rice, koji, yeast, and water bubbling away together for three to five weeks. Everything before it is prep; everything after it is packaging.

Unfiltered — sake that skips the charcoal filtering most sake gets before bottling. It keeps a touch more color, texture, and personality in the glass.

Sake stored unpasteurized while it matures, then heated once at bottling. A halfway house that keeps some of nama's freshness while staying reasonably shelf-stable.

Unpasteurized sake — nama means raw. Vivid, juicy, alive, and famously fragile: keep it cold and drink it happy.

The mirror image of namachozo: pasteurized once before storage, then bottled with no second heating. Hiyaoroshi is the famous example.

Cloudy sake, pressed coarsely so rice solids stay in the bottle. It ranges from a whisper of haze to full milkshake — usually creamy, often gently sweet. Tilt and roll the bottle before pouring.

What Japan actually calls sake. In Japanese, "sake" just means alcohol in general — nihonshu is the rice brew specifically.

The Sake Meter Value (SMV): a density reading that hints at dryness. Positive numbers lean dry, negative lean sweet — a useful clue, though acidity and aroma can override it.

Warmed sake — an art with its own vocabulary of temperatures, from hanabie ("flower chill," lightly cool) up through nurukan (lukewarm) to atsukan (piping hot). Gentle warmth rounds out savory styles like junmai and honjozo beautifully; it's a feature, not a rescue.

The heirloom sake rice — never crossbred since its discovery in 1859. Omachi sake tends to be broad, herbal, and a little untamed; its devotees call themselves Omachists, and honestly, we get it.

The single-serving jar of sake pioneered by Ozeki in 1964 — sake's answer to the tallboy. Once a vending-machine staple, now a canvas for great breweries and delightfully weird labels.

Sake rice: varieties bred for brewing rather than eating, with big grains and a starchy heart (shinpaku) that koji can reach easily. Yamadanishiki and Omachi are the celebrities.

Acidity, as printed on spec sheets. Higher numbers (say 1.8 and up) read richer and more savory; lower ones feel lighter and softer. Handy for guessing a bottle's weight before you open it.

The rice-polishing ratio: how much of each grain remains after milling, so 60% means 40% was polished away. Lower numbers generally mean more delicate, aromatic sake — and a bigger rice bill.

"Freshly pressed" — sake bottled right off the press, usually in winter or early spring, often unpasteurized. Zippy, youthful, sometimes a touch spritzy.

"New sake" — the first releases of the brewing season, arriving in winter. When a brewery hangs a fresh green cedar ball (sugidama) over its door, shinshu has arrived.

The yeast starter, also called moto — a small, carefully guarded tank where yeast multiplies until it's strong enough to take on the main mash. Shubo literally means "mother of sake."

Fizzy sake, from gently spritzy to full champagne-method sparkle. Usually a little lower in alcohol, and a joyful place to start if wine bubbles are your home turf.

Sake aged briefly in cedar casks, picking up a fresh-sawn, forest-walk aroma. Traditional at celebrations, where the barrel lid gets ceremonially smashed open (kagami biraki).

The master brewer — the person responsible for every batch a kura makes. Historically farmers who brewed through the winter; today a role held by an ever-more-diverse crowd.

"Special" — a designation for junmai or honjozo made with extra care: a higher polish, fancy rice, or another step the brewer is proud of. The label's way of saying "we went further."

"Thin nigori" — just a wisp of cloudiness, like a snow flurry in the bottle. All the softness of nigori with none of the milkshake.

The "king of sake rice," grown most famously in Hyogo. Forgiving to brew with and gorgeous in the glass — balanced, elegant, quietly confident. If a rice could win a lifetime achievement award, this one has.

A starter method from 1902 that skips kimoto's pole-mashing but keeps the wild lactic fermentation. Expect bolder, funkier, more savory sake — magnificent warmed.

The microbe that turns koji's sugars into alcohol — and much of sake's aroma along the way. Numbered strains (like #7 or #9) each bring their own personality, from banana to green apple.
