Sake Glossary

Sweet taste profile. Amakuchi sake is noticeably sweet, often with low acidity. The opposite of Karakuchi (dry). Common in Nigori and some regional styles.

The first free-run sake that drips from the pressing bag before pressure is applied. Bold, unrefined, with high effervescence and intense flavor. Often sold as a seasonal limited release.

Ultra-premium sake brewed with rice polished to 50% or less of its original weight. Small amounts of distilled alcohol may be added. The pinnacle of craftsmanship — intensely aromatic with fruit and flower notes.

A rustic, unfiltered sake made without the final pressing step. Thick, rich, and porridge-like in texture. Traditional farmhouse sake, distinct from legal nigori. Brewing doburoku at home is historically restricted in Japan.

A traditional wooden sake press (also called a 'boat press'). Moromi (fermenting mash) is placed in cloth bags inside the fune, then squeezed by gravity and gentle pressure. Produces high-quality, delicate sake.

Undiluted sake — bottled at full brewing strength without the addition of water. Typically 18–20% ABV compared to the usual 15–16%. Richer, more concentrated flavor. Often served on the rocks.

Premium sake brewed with rice polished to 60% or less. Fermented slowly at low temperatures (ginjo-zukuri method). Produces complex fruity and floral aromas (ginjo-ka). Slightly more affordable than Daiginjo.

Sake brewed in winter and released in autumn after maturing through summer without a second pasteurization. Smooth, mellow, and rounded. A beloved seasonal style released around September-October.

Sake brewed with rice polished to 70% or less, with a small amount of distilled alcohol added (up to 10% of rice weight). The alcohol is added to alter aroma and texture, not to increase strength. Light, fragrant, and approachable.

The pressing stage in sake brewing — separating the liquid sake (seishu) from the rice solids (sake lees/kasu) after fermentation. Methods include fune (traditional press), yabuta (accordion press), or fukurozuri (bag hanging).

Pure rice sake — brewed with only rice, water, yeast, and koji. No added distilled alcohol or sugar. Rich, full-bodied, and umami-forward. The foundational designation in sake classification.

Dry taste profile. The opposite of amakuchi (sweet). Karakuchi sake has a crisp, clean finish without residual sweetness. Measured by the Sake Meter Value (Nihonshudo); positive SMV = drier.

Live, actively fermenting nigori sake. Contains live yeast still producing CO2, giving it natural effervescence. Must be handled carefully — the bottle can overflow. Always open with caution. Serve very cold.

An ancient sake starter (shubo) method involving labor-intensive mixing with wooden poles (yamaoroshi) to encourage natural lactic acid development. Creates rich, complex, earthy sake with age potential. Rarely used — traditional breweries preserve the craft.

The mold Aspergillus oryzae cultivated on rice. Koji produces enzymes that convert rice starch into fermentable sugars — the essential first step in sake brewing. Without koji, there is no sake. Sometimes called 'the soul of sake.'

Aged sake, typically 3+ years old. Develops amber-gold color and complex oxidative flavors — caramel, honey, nuts, dried fruit, sherry-like. Rare and adventurous. Often served at room temperature like a dessert wine.

The sake brewery or warehouse. Also called 'sakagura.' Japan has approximately 1,500 active kura, mostly family-owned operations. The kura is both the physical building and the spirit of the brewing tradition.

The brewery workers — the sake makers. They work under the direction of the Toji (master brewer), performing daily tasks of koji-making, fermentation monitoring, pressing, and bottling. Traditional kura work is seasonal and physically demanding.

The main fermentation mash — a mixture of koji rice, steamed rice, water, and yeast shubo. Moromi ferments for 25–35 days, transforming into sake. The parallel fermentation of saccharification and alcoholic fermentation in the same vessel is unique to sake.

Unfiltered sake — not passed through activated charcoal filtration. Retains more of the natural color (slight gold), aroma, and flavor of the moromi. Often paired with namazake or genshu designations.

The middle cut of pressing — sake extracted after arabashiri (first run) and before seme (final press). Considered the most balanced and refined portion, with stable flavor and clarity. Often used for premium expressions.

Unpasteurized sake. Sake is typically pasteurized twice — namazake skips both. This preserves a fresh, lively, vibrant character. Must be kept refrigerated at all times. Drink soon after purchase.

Sake that skips the first pasteurization but is pasteurized once before bottling. Stored unpasteurized, then heat-treated at packaging. Fresher than standard sake but more stable than full namazake.

Sake pasteurized once after the first storage (hiire) but bottled without a second pasteurization. Slightly fresher than conventionally pasteurized sake. Often seasonal — the classic autumn hiyaoroshi is typically nama-zume.

Roughly filtered, cloudy sake. The mesh screen is coarse, allowing rice particles to remain in suspension — giving Nigori its milky white appearance. Generally sweeter, creamier, and richer than filtered sake. Shake gently before pouring.

The Sake Meter Value — a measure of residual sugar content. Positive numbers (+) indicate dryness; negative numbers (-) indicate sweetness. +3 to +5 is considered dry; -3 and below is sweet. Most sake falls between -3 and +8.

See 'Seme.' The final pressing fraction — also called the last-run sake. Higher in bitterness and less refined than naka (middle cut). Sometimes used in blending rather than sold separately.

Acidity level in sake. Higher sando means more acidic — often contributing to a drier, crisper perception. Lower sando gives softer, mellower character. Standard range is 1.0–2.0; most sake is around 1.3–1.5.

The rice polishing ratio — the percentage of the original grain remaining after milling. 60% means 40% was removed. Lower polishing ratio = more premium classification. Daiginjo requires ≤50%; Ginjo ≤60%; Honjozo ≤70%.

The final fraction of pressing — extracted under maximum pressure after naka (middle cut). Higher in amino acids, bitterness, and off-flavors compared to earlier fractions. Used in blending or lower-grade products.

Freshly pressed sake — bottled immediately after pressing without storage or aging. Synonymous with new season's sake, typically released in winter and early spring. Lively, raw, and vibrant. Often namazake as well.

New sake — the freshly brewed sake of the current year. Released from autumn through spring following the winter brewing season. Bright, youthful, and sometimes slightly rough around the edges. Often synonymous with shiboritate.

The yeast starter — also called 'moto.' A concentrated mixture of rice, koji, water, and yeast cultivated to build a large, pure yeast population before the main moromi fermentation begins. The three main methods: sokujomoto, yamahai, and kimoto.

The modern quick-fermentation yeast starter method developed in the early 20th century. Lactic acid is added directly, bypassing the weeks-long natural lactic acid development of kimoto and yamahai. Faster, more consistent, and used by the vast majority of breweries today.

Sake aged or stored in cedar (sugi) wood casks. Absorbs a distinctive woody, cedar fragrance (the aroma is called 'mokushu'). Traditional — cedar barrels were once the standard storage vessel. Now a specialty style for ceremonies and celebrations.

The hottest sake serving temperature — 55°C or above. Rare and intense, used only for very robust, bold sake. Most premium sake should never be served this hot.

The master brewer — the head craftsperson of the kura. Responsible for all decisions in the brewing process, from rice selection to yeast management to pressing. A revered role passed down through apprenticeship. Some toji are celebrities in the sake world.

Special or exceptional — a modifier that can be applied to Junmai (Tokubetsu Junmai) or Honjozo (Tokubetsu Honjozo). Indicates either a lower polishing ratio than required for the base designation, or a special brewing method. Brewer-defined.

A yeast starter method that skips the yamaoroshi (pole-mixing) step of kimoto but still relies on natural lactic acid development (taking 4–6 weeks). Produces rich, complex, sometimes funky sake with high umami and good aging potential. More common than full kimoto.

A pressing method where moromi is placed in cloth bags hanging freely — sake drips out by gravity alone, no pressure applied. Produces the purest, most delicate sake. Extremely labor-intensive and low-yield. Used only for top-tier expressions.

The characteristic fruity, floral aroma of Ginjo and Daiginjo sake — often described as apple, pear, melon, banana, or white flowers. Produced by specific yeast strains fermenting slowly at low temperatures. The hallmark of premium sake.

Sake lees — the solid by-product of pressing. Rich in nutrients, amino acids, and residual alcohol. Used extensively in Japanese cuisine (kasuzuke pickles, amazake, kasujiru soup, marinades). Nothing is wasted in sake production.
