Nagano Sake: Exploring Shinshu's Acclaimed Local Brew Culture

The Characteristics of Nagano Sake—What Flavor Does the Highland Climate Create?

If you had to describe Nagano sake in one word, it would be "clean and easy to drink."

The reason lies in Shinshu's abundant natural environment. Surrounded by mountains over 3,000 meters high including the Northern Alps (Hida Mountains), Central Alps (Kiso Mountains), and Southern Alps (Akaishi Mountains), Nagano Prefecture has snowmelt that slowly seeps into the earth and eventually emerges as clean spring water. This clear water becomes an essential ingredient that creates Nagano sake's flavor!

Additionally, the highland climate with low humidity and refreshing summers and harsh, long winters is an ideal condition for sake brewing. Large temperature swings between day and night help sake rice grow deliciously, and the winter cold is perfect for "cold brewing," which slows fermentation while suppressing harmful bacteria. These three elements—climate, water, and rice—together create the characteristics of Nagano sake.

Flavor Changes by Region! The Character of Nagano Local Sake

One of the great attractions of Nagano sake is how the flavor varies greatly by region.

For example, in the northern Shinshu region bordering Niigata Prefecture, there tend to be more crisp, dry-type sake. In the eastern Shinshu region around Ueda and Saku, there are many refreshing-tasting sake, including the nationally popular "Shinshukameryo." The central Shinshu region around Matsumoto has many sake using snowmelt from the Northern Alps, featuring fruity sake with apple-like aromas like "Daishinshu." In the southern Shinshu region, centered on Suwa, there are many sake with mellow sweetness and good drinkability, with "Masumi" as the representative.

It's fascinating how sake from the same prefecture has such different character! If you try comparing them, the world of sake expands like traveling through it.

The Secret Behind the Flavor Created by Nagano's Water and Rice

Another characteristic is that Nagano sake uses many original sake rice varieties born in the prefecture.

There are no fewer than six varieties of sake rice from Nagano, including "Miyamanishiki," "Hitogokochi," "Kinmonnishiki," and "Yamaeinishiki!" Among them, "Miyamanishiki" is known for producing clean and crisp sake and is widely loved throughout the country. When "Hitogokochi" is combined with spring water from the Northern Alps, it produces a refreshing, fresh aroma.

Regarding water, most sake breweries in Nagano Prefecture use spring water. Most are medium-hard to soft water, and brewing with soft water produces soft, easy-to-drink sake. The difference in brewing water becomes the source of each brewery's "character."

The History and Sake Brewing Tradition of Shinshu Sake

The history of Shinshu sake dates back to the Edo period.

Nagano Prefecture, located at transportation crossroads where multiple highways like the Nakasendo and Hokkoku Kaido passed through, saw sake breweries flourish centered around inn towns. Ueda, Saku, Kiso, Matsumoto, Suwa…unique sake brewing cultures took root in each area and were nurtured alongside the lives of local people—this is "Shinshu's local sake culture."

Currently, Nagano Prefecture has about 80 sake breweries, boasting the second-highest number of breweries in the nation (Nagano Prefecture Sake Brewers Association). Many breweries have long histories, and some have continued sake brewing for over 350 years, such as Okazaki Sake Brewery (brand: Shinshukameryo), founded in 1665. This long tradition combined with technological innovation suited to modern times creates today's Nagano sake.

Original Yeast Supporting Nagano's Sake Brewing

When discussing Nagano's sake brewing tradition, the brewery's unique "yeast" is indispensable.

A microorganism called "yeast" greatly influences Japanese sake's aroma and flavor. Nagano Prefecture's Industrial Technology Research Institute has been developing original yeast varieties. The "Nagano Yeast C (also called Alpine Yeast)" and "Nagano Yeast D" that emerged around 1968 are characterized by fruity aromas reminiscent of Delicious apples. In 2019, a new "Nagano Yeast R" was born, offering rich aroma and acidic flavor.

And there's actually one more impressive thing. The "Kyokai No. 7 Yeast," widely used around the world, was originally discovered at a Nagano sake brewery. Nagano's sake brewing tradition has supported Japan's sake culture nationwide!

Quality Brought by Commitment to Nagano's Rice and Water

What has supported the history of Shinshu sake is an unwavering commitment to raw materials.

Sake rice variety improvement began in the early Showa period. Spurred by rice shortages during wartime, Nagano Prefecture began focusing on developing unique sake rice. Then, in 2020, the latest sake rice "Yamaeinishiki" was born, and this challenge continues even today.

Furthermore, Nagano Prefecture has implemented systems to protect its commitment to quality. The "Nagano Prefecture Geographical Indication (GI) Sake System" that started in 2002 evolved into "GI Nagano" in 2021. Only sake that uses exclusively Nagano-produced rice and water, completes all manufacturing steps within the prefecture, and passes rigorous assessments of taste, aroma, and balance can bear the "GI Nagano" designation. It's a system similar to wine's appellation d'origine contrôlée, and simultaneous designation for both sake and wine was a first nationwide achievement!

Nagano's Local Sake Culture and Selection Guide for Beginners

Nagano's local sake culture has several points worth celebrating nationwide.

Sake using Nagano Yeast C or D is characterized by sweet aromas reminiscent of apples, and many who previously disliked sake find themselves thinking, "I might actually like this!" Indeed, Nagano has many sake loved by younger generations and women.

Additionally, Nagano sake excels as a "food-pairing sake." Shinshu's food culture is rich in fermented foods like miso and pickles, with sweet-savory dishes common to the region. The local sake nurtured with food pairings in mind often has flavors that enhance the deliciousness of dishes. Pairing with Shinshu soba is a classic way to enjoy Nagano when traveling!
