Tokutei Meisho-shu (特定名称酒), or Special Designation Sake, is a formal classification of Japanese sake that meets specific standards for ingredients and rice polishing ratio.

Junmai-shu

Sake made only from rice, rice koji, and water. It offers a rich umami and depth from the rice, with a full-bodied flavor. There are no regulations regarding the rice polishing ratio for Junmai-shu.

Junmai Ginjo-shu

A Junmai-shu with a rice polishing ratio of 60% or less, brewed using the Ginjo (吟醸) method. It is characterized by a fruity, elegant aroma and a clean, refreshing finish.

Junmai Daiginjo-shu

The highest grade of Junmai-shu, with a rice polishing ratio of 50% or less, finished with an even more meticulous Ginjo brewing method. It boasts a delicate, refined aroma and a smooth taste.

Tokubetsu Junmai-shu

A Junmai-shu with a rice polishing ratio of 60% or less, or made using a special brewing method. It reflects the brewery's unique dedication and craftsmanship.

Honjozo-shu

Sake made from rice with a polishing ratio of 70% or less, with a small amount of brewer's alcohol added. It has a clean, crisp taste and is also well-suited for warming (kanzake).

Tokubetsu Honjozo-shu

A Honjozo-shu with a rice polishing ratio of 60% or less, or made using a special brewing method. It offers a more refined taste than standard Honjozo-shu.

Ginjo-shu

Sake with a rice polishing ratio of 60% or less, brewed using the Ginjo method. The addition of brewer's alcohol enhances its fruity aroma.

Daiginjo-shu

The highest grade of Ginjo-shu, with a rice polishing ratio of 50% or less. It features an elegant aroma and a clean finish, making it popular for gifts.

Types of Sake by Brewing Method

Sake is further categorized based on the presence or absence of pasteurization (hi-ire), dilution (kasui), and filtration (roka).

Classification by Pasteurization

While standard sake undergoes hi-ire (火入れ), or heat pasteurization, before shipping, sake is also classified by whether or not this process is performed.

Namazake (生酒) is sake that has not been pasteurized at all, offering a vibrant, freshly pressed flavor. Refrigeration is essential.

Nama-chozo-shu (生貯蔵酒) is sake that is not pasteurized during storage but undergoes a single pasteurization just before shipping. It balances the freshness close to Namazake with improved shelf stability.

Nama-zume-shu (生詰め酒) is sake that is pasteurized once before storage but not again before bottling. "Hiyaoroshi" and "Akiagari" are examples of this type.

Classification by Dilution

Standard sake is typically diluted with water to adjust its alcohol content before shipping. Sake is also classified by the presence or absence of this dilution.

Genshu (原酒) is undiluted sake, with a higher alcohol content of 17-20%. It offers a concentrated umami from the rice.

Kasui-shu (加水酒) is standard sake, with its alcohol content adjusted to around 15-16%.

Classification by Filtration

Standard sake is usually filtered after pressing. Sake is also classified by the presence or absence of this filtration.

Muroka-shu (無濾過酒) is sake where the filtration process is omitted, retaining a golden hue and complex flavors.

Rokashu (濾過酒) is standard sake, characterized by its clear appearance and clean taste.

Muroka Nama Genshu

Muroka Nama Genshu (無濾過生原酒) is sake that skips all three processes: filtration, pasteurization, and dilution. It is considered the closest to sake in its most natural state, offering a true essence of sake.

Types of Sake by Style

Beyond traditional classifications, some sake types are distinguished by their flavor profile or brewing style.

Nigori-shu

Nigori-shu (にごり酒) is a cloudy white sake that is only coarsely filtered through a cloth, leaving some of the moromi (醪), or fermenting mash. It offers a creamy umami and sweetness derived from the rice.

Kassei Nigori-shu

Kassei Nigori-shu (活性にごり酒) is an "active" Nigori-shu where fermentation continues in the bottle. It provides a refreshing, fizzy sensation. Be careful when opening, as it may fizz over!

Origarami

Origarami (おりがらみ) is a lightly cloudy sake, less opaque than Nigori-shu, with a small amount of lees (ori, 澱) remaining. It offers an exquisite balance of freshness and rice umami.

Sparkling Sake

Sparkling sake is effervescent sake infused with carbon dioxide, often through secondary fermentation in the bottle. It provides a refreshing sensation similar to champagne and is popular as a celebratory drink.

Koshu / Aged Sake

Koshu (古酒) or aged sake is sake that has been matured for three years or more. It develops an amber color and a rich flavor, with a unique aroma reminiscent of Shaoxing wine.

Kijoshu

Kijoshu (貴醸酒) is a rich, sweet sake brewed by replacing some of the water with sake during fermentation. It can be enjoyed as a dessert wine.

Taruzake

Taruzake (樽酒) is sake aged in cedar barrels. It takes on the aroma of cedar, offering a distinctive flavor.

Yamahai-jikomi

Yamahai-jikomi (山廃仕込み) is sake brewed using the traditional "Yamaoroshi Haishi Moto" method, which omits the labor-intensive mashing of the starter mash. It is characterized by strong umami and acidity, making it suitable for warming.

Kimoto-jikomi

Kimoto-jikomi (生酛仕込み) is sake brewed using the most traditional "Kimoto" method for creating the starter mash. It features a complex and profound flavor.

Seasonal Limited Edition Sake

There are also limited edition sakes that can be enjoyed seasonally.

Shiboritate

Shiboritate (しぼりたて) is freshly pressed sake that appears on the market during the new sake season, from winter to spring.

Shinshu

Shinshu (新酒) is the newest sake brewed in the current year. It offers a fruity and youthful flavor.

Hiyaoroshi

Hiyaoroshi (ひやおろし) is sake that has matured over the summer and is released in autumn. It has a mellow and rich autumnal flavor.

Akiagari

Similar to Hiyaoroshi, Akiagari (秋上がり) refers to sake whose flavors have fully developed in autumn, often indicating a more mature and refined brew.

Characteristics of Sake by Region

The flavor profile of sake also varies depending on its region of origin.

Niigata Prefecture is known for its tanrei karakuchi (淡麗辛口), or light and dry, clear taste. Nada in Hyogo Prefecture is famous for its robust flavor, often called otoko-zake (男酒) or "masculine sake," while Fushimi in Kyoto is known for its soft taste, referred to as onna-zake (女酒) or "feminine sake."

Yamagata and Fukushima Prefectures tend to produce elegant and fruity sakes. Akita and Iwate Prefectures are known for clean and mild sakes, while Yamaguchi and Hiroshima Prefectures often produce distinctive and aromatic sakes.

Enjoying Jizake (地酒), or local sake, and experiencing the regional characteristics is one of the many charms of Japanese sake.
