Sakes must be labelled with the following items using Japanese characters with a minimum font size of Xpt.
8 pt. font minimum
- Raw ingredients
Listed in order of descending weight
Specially designated sake, rice-polishing ratio must be shown adjacent to the ingredient listing - Date of production
300ml bottles or less can omit word “date” - Precautions for storage or consumption
required for nama-zake - Country of origin if imported
- Labeling of products containing sake produced overeas
Country of the produced sake and ratio
Obligated to also list:
- Name of brewer or brewery
- Brewery location
- Word “seishu” or “nihonshu”
- Alcohol content. If effervescent with less than 10% abv, must be labelled “effervescent” and indicate “tax rate application classification”
Voluntary information on label. May be indicated on label if applicable
- Rice variety
If the ratio of the particular rice exceeds 50% - Production area
If sake was entirely produced in said area - Aging period
If aged for 1 year or longer, rounding down - Genshu
However, permissable to add water within a range that reduces the alcohol content by less than 1% - Nama-zake
- Nama-chozo-shu
- Ki-ippon
Brewed solely at a single production facility - Taruzake
Stored in wooden csk and has acquired KIGA (cedar aroma) - Gokujo (excellent quality), yoryo (fine quality), kokyu (premium)

Prohibited labeling terms
- Saiko (best), Dai-ichi (#1), Daihyo (representing or leading)

What is sei-hakumai
polished white rice
What are the two species of rice
Asian rice
African rice
What are the two subspecies of Asian rice
Japonica (short grain)
Indica (long grain)
Within the two subspecies of Asian rice, it can further be categorized into:
uruchi-mai (non-glutinous)
Mochi-gome (glutinous)
Two cultivation methods of rice
paddy rice
upland rice (grown on farmland)
What are the names of rice suited for sake brewing?
Shuzo koteki mai (sake-brewing rice)
Koteki mai (brewer’s rice)
Saka mai (sake rice)
Shuzo mai (sake-brewing rice)
What is ippan-mai or han-mai
Table rice
Usually Japonica, non-glutinous, paddy rice
What is mochi-gome-yondan
Using glutinous rice in the fourth stage of mashing
Rice properties suitable for brewing
- Resistance to breakage during polishing
If rice breaks, cause unevenness in size/shape resulting in adverse effect on manufacturing process - Large-grained rice
Sake rice usually over 26g senryuju (thousand-grain weight). Normal table rice between 20-30g - Has shinpaku
Has good absorbency properties
Good solubility in moromi
Promotes koji with high enzymatic activity
Allows koji-kin mycelium to penetrate into gaps of shinpaku - Low protein content
High protein content reduces absorbency and lowers dissolvability. Increases amino acidity, degrades color and aroma. Usually 7-8% of brown rice, 4-6% white rice - Soft-textured rice
takes less time to polish, good absorbency, dissolves well
Shinpaku appearance rate factor
high appearance rate is a requirement for sake brewing rice
Found more commonly in large-grain rice
Controlled by genetic factors (rice variety)
Climate and cultivation conditions such as diurnal temperature. The bigger the diurnal temp range, the higher the appearance rate
Shinpaku shapes and properties
Shapes: linear, spherical, dotted, eye-shapes
Linear suitable for high polishing
Eye-shaped & spherical prone to cracking durin gpolishing but has superior absorbency and saccharification properties
