This glossary of sake terms lists some of terms and definitions involved in making sake, and some terms which also apply to other beverages such as beer. Sake, also referred to as a Japanese rice wine, is an alcoholic beverage made by fermenting rice that has been polished to remove the bran. Unlike wine, in which alcohol is produced by fermenting sugar that is naturally present in fruit, sake is produced by a brewing process more akin to that of beer, where starch is converted into sugars which ferment into alcohol.

Acidity

The quality of sake that gives it its crispiness and vitality. A proper balance of acidity must be struck with the other elements of a sake, or else the sake may be said to be too sharp – having disproportionately high levels of acidity – or too flat – having disproportionately low levels of acidity.

Alcohol

Generally refers to ethanol, a chemical compound found in alcoholic beverages. It is also commonly used to refer to alcoholic beverages in general.

Alcoholic fermentation

The conversion by yeast of sugar into alcohol compounds

Amakuchi 甘口

Sweeter than neutral sake

Amazake 甘酒

A traditional sweet, low-alcoholic Japanese drink made from fermented rice.

Aminosan-do アミノ酸度

The taste of umami or savoriness. As the proportion of amino acids rises, the sake tastes more savory. This number is determined by formol titration of the sake with a mixture of sodium hydroxide solution and formaldehyde, and is equal to the milliliters of 0.1mol/L sodium hydroxide required to neutralize the amino acids in 10 mL of sake.

Atsukan 熱燗

Heated sake; typically only lower-quality sake is served hot, as high heat tends to destroy subtle flavors and aromas. Mostly consumed in cold winter months.

Daiginjō-shu 大吟醸酒

Doburoku 濁酒

The classic home-brew style of sake although home brewing is illegal in Japan. It is created by simply adding kōji mold to steamed rice and water and letting the mixture ferment. The resulting sake is somewhat like a chunkier version of nigorizake.

Teiseihaku-shu 低精白酒

Sake with a deliberately high rice-polishing ratio. It is generally held that the lower the rice polishing ratio (the percent weight after polishing), the better the potential of the sake. However, beginning around 2005, teiseihaku-shu has been produced as a specialty sake made with high rice-polishing ratios, usually around 80%, to produce sake with the characteristic flavor of rice itself.

That step of the kimoto method is known as yama-oroshi, and the full name for yamahai is "yama-oroshi haishi" (山卸廃止), meaning "discontinuation of yama-oroshi." While the yamahai method was originally developed to speed production time, it is slower than the modern method and is now used only in specialty brews for the earthy flavors it produces.
