The rice &
sake-rice varieties
Sake begins with a grain most people never think about: a special rice, chosen and grown for brewing, with a starchy heart the whole process is built to reach.
The grain behind the glass
Sake is as varietal as wine — but the rice sets a ceiling that the brewing then chases. Click through:
Hold two ideas together: sake rice genuinely matters — a big, clean shinpaku lets a brewer polish hard and aim high — but as in every craft course, process (polishing, koji, fermentation, water) shapes the glass more than the rice’s name does. And note the silent partner: water is ~80% of sake, doing quiet work the rice gets credit for. We’ll return to both in Sessions 15–16.
Read your bottle as a grain
Find the rice
Check your sake for a rice variety — Yamada Nishiki, Gohyakumangoku, Omachi, or a blend. Brewers who name it usually chose it deliberately.
Predict the style
Guess before you taste: Yamada Nishiki should read clean and elegant; Omachi, richer and earthier. You’ll test this in Session 16.

From memory:
- How does sake rice differ from table rice?
- What is the shinpaku, and why does it matter?
- Name the benchmark sake rice.
- Does rice variety or production matter more for flavor?
- Roughly what share of sake is water?
Polishing:
the seimaibuai axis
The single most important number in sake — and this course’s central production lever. How far the rice is milled sets the grade, the style, and much of the price.
The master lever
If you learn one production fact about sake, learn this one. Click through the polishing axis:
The grade matrix
Set the polishing ratio and answer the one other question — was distilled alcohol added? — and watch the exact grade appear. This is the whole premium grade system, live. Note how a single move (adding alcohol) flips junmai daiginjo → daiginjo without changing the polish at all.
Locate your sake
Find the ratio
Read the seimaibuai off your bottle (a % like 60% or 50%). Set it on the matrix above, with or without alcohol, and confirm the grade matches the label.
Feel the style, not the score
Remind yourself: a lower number promises more delicate and fragrant, and costs more — but it isn’t a rating of how much you’ll enjoy it. Style dial, not quality score.

From memory:
- What does seimaibuai measure — and does lower mean more or less polishing?
- What does more polishing do to the style?
- Give the daiginjo and ginjo thresholds.
- Why is daiginjo expensive?
- Why read the ratio as a style signal, not a quality score?
Washing, soaking
& steaming
The unglamorous prep steps that decide whether everything after them can succeed. Invisible on the label, decisive in the glass — and, for top sake, timed to the second.
Getting the rice ready
Between polishing and brewing sits a run of precise, humble steps. Click through:
You’ve met this pattern in every craft course — olive oil’s tree-to-mill dash, coffee’s cherry processing. Here it’s water absorption and steam texture: nothing a label ever shows, yet get it wrong and the koji grows unevenly and the fermentation stumbles. Great prep can’t make great sake by itself, but bad prep guarantees it won’t happen.
Appreciate the unseen
Notice what’s not on the label
Recognize that the care in washing, soaking, and steaming — like koji-making next — is exactly what a price tag pays for, even though no marketing word captures it.
Connect to freshness
Steamed, split, cooled rice is perishable and time-sensitive — a first hint of why sake, too, rewards freshness (Session 9).

- What three uses is the steamed rice split into?
- Why call prep an "invisible but decisive" step?
