What sake is,
& how to taste it
First, undo two myths: sake is not "rice wine," and it is not a spirit to knock back warm. It's brewed — closer to beer than wine — through the most intricate fermentation in the drinks world, and the best of it is a delicate, aromatic thing you sip cool from a wine glass. Grasp how it's made and one number — the polishing ratio — and its grades, flavors, and rituals all line up. This session sets that, then hands you the six-axis instrument for all twenty sessions.
Brewed, not fermented grapes or distilled spirit
Almost everything people get wrong about sake comes from filing it under "wine" or "spirit." It's neither. Click through what it actually is:
Because sake is brewed from rice, the defining choices are how much you mill that rice (seimaibuai, Sessions 5, 10), how you run a mold and a yeast together (Sessions 7, 8), and whether you serve it cool or warm (Session 17). There are no grapes, no barrels, no distillation. Hold "brewed rice, polished to a core" and the whole map draws itself.
How to taste sake
Forget the tiny ceramic cup and the hot pour for now — that's a serving ritual, not a tasting method. To actually read a sake, treat it like fine wine:
Use a wine glass, lightly chilled
Pour a small measure of a premium sake (a ginjo or daiginjo) into a white-wine glass at cool fridge temperature, ~10°C. A glass with a bowl concentrates the aromatics a thimble cup hides.
Look, then nose
Most sake is clear to pale straw (color says little). Swirl gently and smell: premium sake can throw astonishing fruit and flower — melon, green apple, banana, pear, anise. That aromatic lift has a name, ginjo-ka, and it's the first thing the instrument measures.
Sip and coat the palate
Take a small sip and let it spread. Sake's magic is umami — a savory, almost broth-like depth grapes never give — laid over a sweet–dry balance and a soft acidity. Look for all three.
Weigh the body
Notice whether it feels light and clean (tanrei) or full and rice-rich. This "weight" separates a crisp Niigata sake from a broad, savory junmai as clearly as anything.
Judge the finish
Does the flavor vanish crisply (kire) or linger with rice and umami? Note anything off — harsh alcohol, sourness, a flat cardboard staleness. Clean length is quality.
Read the structure
Set each axis for the sake in front of you; the instrument reads the combination back. These six axes describe almost any sake and recur in every later session.
Beginners reach for "smooth" and "clean," which describe almost nothing. Read instead for fragrance, sweetness, acidity, body, umami, and finish, and "it's sake" becomes "a fragrant, dry, light daiginjo" or "a rich, umami-driven junmai you'd warm." That move — from vague to structural — is the whole course.
Taste one sake properly
Pour a premium sake, cool
Ideally a ginjo or daiginjo (the fragrant end), in a wine glass at ~10°C. If all you have is an inexpensive bottle, that's fine — you'll just sit lower on fragrance.
Nose, sip, and log all six axes
Work slowly. Hunt the fruit/flower aromatics, then the sweet–dry balance, the soft acidity, the body, and above all the umami — the savory depth that tells you this isn't wine.
Name the umami
If you catch a broth-like, savory, moreish quality under the fruit, you've found sake's signature. That's your baseline for every comparison to come.

From memory:
- Why is sake "brewed," and closer to beer than wine?
- What are the four ingredients of sake?
- Why taste premium sake from a wine glass, cool — not a hot thimble cup?
- What is umami, and why does it matter for sake?
- What are the six axes of the instrument?
Calibration & the
flavor wheel
Fix your reference points for the six axes, meet the two numbers you'll see on labels — SMV and acidity — and work from flavor families instead of guessing, including the faults that tell you a sake is past its best.
The sensations you're measuring
Separate these and your notes stop being "nice" and "smooth."
Two of these axes have industry numbers you'll meet on back labels, so anchor them now. Sake Meter Value (SMV, or nihonshu-do) scores sweet–dry: positive = drier (karakuchi), negative = sweeter (amakuchi). Acidity (sando) is a small number, usually ~1.0–2.0, where higher reads firmer and more savory, lower reads softer and rounder. You'll map both fully in Session 13; for now, just know the words.
The flavor wheel — and the faults
Rather than "tastes like sake," work from families. The first families are positive; the last chip is the group that signals a tired or badly kept bottle. Click each:
Start broad: is this sake fragrant (fruity/floral — a ginjo signature) or quiet and savory (rice, umami — a classic junmai)? Then narrow. And run the fault check: a harsh solventy note, sourness, or flat cardboard/sherry staleness usually means the bottle is old, heat-damaged, or oxidized (sake is generally best young and cool-stored). Naming faults matters as much as naming aromas.
Anchor fragrant vs savory
Find the aromatic pole
In a ginjo/daiginjo (or the more fragrant of two bottles), hunt fruit and flower — melon, apple, pear. Name it. That's "fragrant."
Find the savory pole
In a junmai (or the richer bottle), look past fruit for rice, cereal, and that broth-like umami. That's "savory/rice-driven."
Name families first
For each sake, commit to fragrant-vs-savory, then a family or two, before chasing specific notes.

The grade spine
at a glance
One orientation before the production block: premium sake is sorted by a single number — how much of the rice grain was polished away — plus one yes/no question: was a little distilled alcohol added? Learn that two-part logic now and every label word (junmai, ginjo, daiginjo, honjozo) becomes readable.
The premium grades, and the table sake below
Almost every premium word on a sake label is set by polishing plus the alcohol question. Click through the ladder:
This is sake's version of tea's oxidation dial or olive oil's grade ladder — but unusually clean, because it rests on one measured number. Block C (Sessions 10–14) walks it slowly; for now hold the shape: more rice polished away = more delicate and fragrant; "junmai" = no added alcohol; the premium family is called tokutei-meishoshu, and everything else is everyday futsu-shu.
The two levers — and a warning about "premium"
To place any premium sake you ask two questions. Polishing: what's the seimaibuai — the % of the rice grain remaining? Lower means more milled away: ≤70% opens honjozo/junmai territory, ≤60% ginjo, ≤50% daiginjo. Alcohol: was a small amount of distilled brewer's alcohol added? If not, the word junmai ("pure rice") goes in front. That's the entire matrix.
Here's the trap to disarm early: a lower polishing ratio means a more refined, delicate, aromatic sake — and it costs more to make — but it does not automatically mean you'll enjoy it more. A highly-polished daiginjo and a rich, rustic junmai are different pleasures, like a delicate filet and a great burger. Brewer skill, rice, and water matter as much as the number. Read the ratio as a style signal, not a quality score — a theme we'll return to in Session 11.
Place what you own
Read your bottle's grade
Find the grade word — junmai, honjozo, ginjo, daiginjo, or a combination — and the seimaibuai (a % like 60% or 50%) if it's printed. Place it on the ladder.
Run the two questions
Ask: how polished (the %)? and pure-rice or alcohol-added (junmai or not)? You now hold the target you'll aim at through the whole production block.
