Let us begin our journey into the world of sake.

What is Sake?

Sake, often referred to as “Japan’s national beverage,” is an alcoholic drink made from rice, water, koji (a type of mold), and sometimes yeast. Thanks to its unique brewing process, sake possesses a distinctive taste and aroma that sets it apart from any other alcoholic beverage in the world. The alcohol content of sake typically ranges from 15% to 20%, and there are numerous varieties. Its characteristics are shaped by the rice variety used, the quality of the water, the type of koji, and the differences in the brewing process.

The appeal of sake lies in its diversity. From seishu (clear sake) to junmai-shu and daiginjo-shu, the varieties are extensive, each with its own unique flavor and characteristics. Moreover, the taste changes with temperature, making it enjoyable both chilled and warmed (atsukan), allowing for a variety of ways to savor it depending on your mood or the meal.

Beyond its brewing techniques and flavors, sake is deeply rooted in Japanese food culture and traditions. It is an indispensable part of Japanese life, enjoyed as a celebratory toast at festivals and special occasions, or shared at meals with family and friends.

History of Sake

The history of sake dates back more than 1,300 years. Brewing techniques introduced from China during the Nara period adapted to Japan’s soil and climate, undergoing unique developments. In its early days, sake was a precious beverage consumed exclusively by the imperial court and aristocracy during special ceremonies and rituals. During the Heian period, sake brewing became more refined, and various methods were experimented with.

From the Kamakura to Muromachi periods, monks and temples became the center of sake brewing, and techniques advanced significantly. During this era, sake brewing was closely linked to Buddhism, and many temples produced sake. It was also during this time that the foundational brewing technique known as “moto” was established, laying the groundwork for modern sake production methods.

During the Edo period, sake became widely available to common people. Consumption increased in urban areas, and sake brewing developed as a commercial industry. Advances in brewing techniques during this era led to the creation of various types of sake. In particular, more delicate and flavorful varieties such as junmai-shu and ginjo-shu were born, contributing to significant improvements in sake quality.

From the Meiji period onward, the introduction of sake taxation by the government and innovations in brewing technology further advanced sake production. Scientific research and technological progress stabilized quality and enabled the production of sake with diverse flavors.

Even today, sake continues to be cherished worldwide as a culture that values both tradition and innovation. It is highly regarded on the international stage, and the popularity of sake outside Japan continues to grow. Throughout its long history, sake has become a symbol of Japanese culture and tradition, and it continues to evolve to this day.

Types of Sake

Sake encompasses a wide variety of classifications, and understanding them is essential for a deeper appreciation of this beverage. The main classifications are determined by the ingredients used and the brewing process. Here, we introduce the major types of sake and their characteristics.

Junmai-shu (Pure Rice Sake)

Junmai-shu is sake made exclusively from rice and rice koji, without the addition of brewed alcohol. It allows you to enjoy the true flavor of rice, with a rich aroma and deep, complex taste.

Ginjo-shu (Premium Sake)

Ginjo-shu is made from rice that has been milled to 50% or less of its original size. A small amount of brewed alcohol may be added, resulting in a fruity and delicate aroma and flavor.

Daiginjo-shu (Super Premium Sake)

Daiginjo-shu is made with rice milled to 50% or less and is fermented at low temperatures over an extended period, resulting in an exceptionally fragrant aroma and a complex, refined flavor. Its production requires extremely advanced techniques.

Honjozo-shu (Standard Brewed Sake)

Honjozo-shu is made from rice milled to 70% or less with added brewed alcohol. It has a well-balanced flavor and is generally among the more reasonably priced sake varieties.

Tokubetsu Honjozo-shu (Special Brewed Sake)

Tokubetsu Honjozo is a sake that places even greater emphasis on quality than regular Honjozo, through higher rice polishing ratios or the use of special yeast strains. It features a distinctive fruity aroma and flavor.

Junmai Ginjo-shu (Pure Rice Premium Sake)

Junmai Ginjo-shu is a Junmai sake that employs Ginjo brewing methods. Without added brewed alcohol and with a low rice polishing ratio, it achieves an elegant aroma and delicate flavor.

Junmai Daiginjo-shu (Pure Rice Super Premium Sake)

Junmai Daiginjo-shu is the highest grade of sake among the Junmai Ginjo category, with an even lower rice polishing ratio and extended low-temperature fermentation. It possesses an exquisitely refined aroma and flavor.

In addition to these, there are many other types such as nama-zake (unpasteurized sake), nigori-zake (cloudy sake), and koshu (aged sake), which vary by preservation method and drinking style. Since the taste of sake differs greatly depending on the type, exploring various varieties to find your personal favorite is one of the great pleasures of sake.

How Sake is Made

The sake-making process involves complex and delicate steps that give rise to its distinctive flavors. Below, we introduce the basic steps of sake production.

Rice Selection and Polishing

The rice used for sake is specifically selected from varieties known as “shuzo kotekimai” (sake-brewing rice). Polishing refers to the process of removing the outer layers of the rice grain, and the degree of polishing determines the type of sake produced. The lower the polishing ratio, the less protein remains on the outer layer, allowing for a purer starch content.

Washing, Soaking, and Steaming

The polished rice is washed, soaked in water for an appropriate duration, and then steamed. This steamed rice forms the basis for koji-making (adding koji mold) and moromi-making (adding yeast for the main mash).

Koji Making

Koji mold is sprinkled onto a portion of the steamed rice, which is then maintained at a consistent temperature and humidity while the mold propagates. The koji mold plays a crucial role through its saccharification function, converting the starch in rice into sugar.

Brewing (Shikomi)

Koji, steamed rice, water, and yeast are combined to create the moromi (main mash). This moromi is fermented over a period of several days to several weeks. Temperature control during the fermentation process is extremely important, as it greatly affects the flavor of the sake.

Pressing (Shibori)

Once fermentation is complete, the moromi is placed in cloth bags and pressed to extract the liquid. This extracted liquid is sake. The pressing method also creates differences in the flavor of the sake.

Pasteurization (Hi-ire)

After pressing, sake is typically heated once (hi-ire) to stabilize its quality and enable long-term storage.

Aging (Jukusei)

After pasteurization, sake is aged for a certain period before bottling. Through this aging process, sake develops a smoother and deeper flavor.

In addition to these basic steps, the unique techniques and philosophies of individual brewers contribute to the creation of a vast array of sake flavors. The fusion of traditional techniques and modern science continues to expand the infinite possibilities of sake.
