New Trends in the Sake Industry

In recent years, more companies have shifted from using the term “diversity” to the broader acronym “DEI”—Diversity, Equity, and Inclusion—to describe their initiatives and strategies. DEI represents a state where individuals of diverse genders, nationalities, and abilities collaborate in an equitable and inclusive environment.  In the SAKE Street feature “Women in the Sake World,” a three-part series, we spotlight women, a group historically marginalized within the sake industry, to examine what is necessary to build a more inclusive landscape—one where all individuals can work without barriers.  As gender diversity gains recognition globally, with more people acknowledging identities beyond the traditional male-female binary, many industries are actively addressing gender-related challenges to foster comfort and equity. However, the sake industry, steeped in tradition, is still on the journey toward this transformation.  In the first installment of this series, we delve into the unique challenges women face in sake brewing, drawing on insights from a survey (*) of 50 women who have worked in the field. What barriers do these women encounter as they pursue careers in sake brewing, and what steps are needed to ensure they can thrive in this industry long-term?  *The survey was conducted online from June 5th to 20th, 2024. We received 50 responses through social media, the female brewery workers' community, and other means of dissemination. The breakdown was 50% for those in charge of production and 50% for those not in charge of production.

Maibijin, known among aficionados as the "deviant sake," is unforgettable once tasted, captivating enthusiasts with its unique flavor.

Rice is one of the key factors in determining the quality of sake. The rice used in sake brewing differs from everyday eating rice, as it has been specially cultivated to enhance the flavor of sake. In this article, we will explore the characteristics of high-quality sake rice and the grading system used to assess it.

Water is a critical component in the production of sake, comprising approximately 80% of its ingredients. Many brewers underscore the unique role of water in sake-making, distinguishing it from wine, which is made without the use of water. While rice can be transported over long distances, the vast quantities of water required for brewing make it impractical to move, meaning the availability of high-quality water has historically been a key factor when selecting a brewery location.  However, discussions surrounding water’s regional characteristics are often limited to its hardness—whether it’s soft or hard water—leaving much unknown about the specific qualities of water in different regions. To address this gap, the Yamanashi Prefecture Sake Brewers Association launched a comprehensive water quality research project from 2023 to 2024. Spearheaded by a team of geologists, the project delved into the geology of Yamanashi Prefecture to explore how it influences the water used in sake production.  To what extent can the relationship between local water sources and the character of sake be scientifically traced? In this article, we explore the findings of this groundbreaking research and examine how regional water quality shapes the unique terroir of sake.

In recent years, the term "craft sake" has gained popularity in discussions about Japanese sake. However, there is no legal definition, and the term is used to describe a wide range of products. In this article, we will explore various examples to better understand what craft sake truly means.

What is Craft Sake? From the Original Meaning to How It Is Used These Days

In sake brewing, there is a saying “1 for koji, 2 for moto (yeast starter), and 3 for tsukuri (fermentation)” based on the order of importance of the process. Koji, which is considered the most important, is probably more commonly seen as a way to add flavor and aroma these days.  There are several types of koji, including yellow, black and white koji. Among these, yellow koji is the one traditionally used for sake. Yellow koji is also the raw material for miso and soy sauce, and is an essential part of Japanese food.  In this article, let's learn about the history of yellow koji and how it differs from other types.

Dassai, produced by Yamaguchi Prefecture's Asahi Shuzo, is such a well-known a brand that many non-sake fans recognise the name; its popularity began to grow around 2010, and its production is now about 70 times higher than 30 years ago. The brewery used to be recognised as a small brewery located deep in the mountains, but by spring 2015, a new 12-story building took its place.  Due to its large production volume and advanced brewing equipment, people sometimes feel that Dassai is made entirely by machine, but we suspect something different, so we visited the brewery in Yamaguchi Prefecture to check it out.

Sake with a smaller rice polishing ratio (i.e., more rice is removed), such as ginjo and daiginjo, has a clear, clean taste with less unwanted flavors. This is because the more rice is polished, the more protein, lipid, and other components are removed, which can cause an unpleasant taste. But did you know that you can reduce unwanted flavors not only by reducing the milling ratio value, but also by changing the way rice is polished? In this article, we will cover three methods of polishing rice: spherical (kyukei), original (genkei), and flattened (henpei). For each method, let's learn about the shape of the rice after milling and its characteristics in sake brewing.

Rice, which is the raw ingredient for sake, contains starch. While starch is the source of sugar, it in itself does not contain any sugar. Therefore, another ingredient, koji, is indispensable for sake brewing, allowing the production of alcohol from rice.

Most people know that sake is made from rice and water but what about the actual process? When you know how sake is made, you will be able to better enjoy it as you have an increased appreciation for the various methods to get it to taste the way it does. The exact process of brewing sake differs from brewery to brewery but I will illustrate here the general process.

How is Japanese sake made?

Within sake making, there is the step of making "shubo". As the adage "First koji, then moto, and lastly tsukuri" highlights, the second most important element of sake making is this "moto" which is just another name for shubo or yeast starter. Depending on the type of shubo, the process is slightly different, each giving the resulting sake a unique taste and aroma which we will explore.

Often heard that they don’t drink sake because it makes them fat.

Ever seen the words 'polishing ratio xx %' written on a sake bottle? The polishing ratio greatly affects the taste and aroma of sake. It also affects whether you are permitted to call the sake certain names such as 'Junmai Daiginjo' and 'Ginjo'. By understanding the polishing ratio, you will be able to better understand the sake that you choose, so let's take a look!

What is the "Polishing Ratio" often seen on Japanese Sake?

One unique characteristic of Japanese sake compared to wine or beer is that it can be enjoyed at a wider range of temperatures. Changing the temperature even slightly can alter the aroma and taste, and therefore the same sake can be joined in multiple ways depending on your mood! At the same time, if you have it at the wrong temperature it can also ruin the sake, killing the very features that make it! Here I will be sharing with you how sake changes at different temperatures as well as how to select a suitable temperature according to the type of sake.
