Sake Curator: Future AI Cafe

しぶちかshibuchika, an underground shopping street at the intersection in front of Shibuya Station in Tokyo, opened an exhibition-style coffee shop "AZLM CONNECTED CAFE" on 7/1, where you can drink specialty coffee at 99 yen including tax, and the store also displays There are about 300 various products that can be marketed, providing opportunities for those who come to the store to see, touch and apply.

The store is a cashless transaction using AmazonPay (payment methods will be added in the future), so you need to log in as a member of AZLM CONNECTED CAFE and download the Amazon Alexa-enabled APP before consumption. If you log in as a member after arriving at the coffee shop, when you need assistance, the staff in the shop can explain or operate the temi robot configured in the shop.

It's all about taking money in exchange for a coffee discount.

There is also a temi for personal diagnosis of Japanese sake. It recommends the Japanese sake displayed in the store through the interface operation, and when the recommendation result comes out, the lights in the display area of the displayed wine will flash to inform you of the location, and then go to get the recommended one. Wine to understand product information. If you want to learn more, you can chat with Zang Yuan through the in-store tablet. In addition, like other displayed products, you can scan the QR code to connect to the online store and buy your favorite Japanese sake.

As a thrifty person, how can you foolishly buy at the designated EC, of course, you have to shop around and earn membership points yourself. As for the recommendation system, don't worry about how to launch what content, just look at the smoothness of the linkage between software and hardware.

AZLM introduces NTT East Japan's ICT technology, and uses AI cameras to determine the age, gender, interest in products and other data of visitors, and feed them back to exhibitors called "JOIN members". It is suitable for those who want to open a store in the metropolitan area but hesitate to move forward because the rent is too expensive, or consider the product launch to test the water temperature.

Niigata University Nippon Sake Research Center Base Facility

Niigata University, where the course "Sake Studies" is taught, has opened the "Niigata University Center for Sake Studies" as its research base, and the opening ceremony will be held at Niigata University Igarashi Campus on July 2, 2021. The Sake Science Center was established as a research base for Sake Science. In addition to the Sake Tasting Practice Room and the Test Brewing Room, there are more than 50 kinds of specialized machines such as machines for analyzing the taste and smell of Japanese sake. Research Japanese sake.

In 2017, Niigata University signed an agreement with the Prefectural Sake Brewing Association and the prefectural government, and in 2018 established the "Sake Science Center", with the participation of teachers from interdisciplinary departments who study issues such as brewing and fermentation, economics, and health. In addition to the "Sake Studies" lectures that all undergraduates can attend, there is also an exchange with the University of Bordeaux in France.

Up to now, each faculty has conducted research in their own laboratories, but special research assistants are permanently stationed in special facilities. The existing facility will be converted into a research laboratory that can perform brewing and analysis. In the future, the aroma and taste will be analyzed for the improvement of yeast varieties, and scientific research will be conducted on the compatibility of food and Japanese sake.

Jiazhen wine

Music to the mash is nothing new. Music is used to stimulate the yeast during the fermentation process, and it is said that there is a difference between fermentation and maturation. However, in the past, speakers were often used to emit music. The general sounding principle of speakers is to drive a vibrating plate to vibrate the air to produce sound, but it is not suitable for humid places. Another way to play music is Onkyo's patented vibrator Vibtone. After attaching the vibrator to the board/barrel wall, let the vibrator drive the board/barrel wall to vibrate, and make the surrounding air emit sound through resonance. Set up where waterproof or airtightness is required.

ONKYO started joint research with Tokyo Agricultural University in July 2020, trying to understand how the composition and function of yeast change when a vibrator is used during fermentation, such as different vibration setting conditions, or the frequency of sound What effect does the difference in the range have on the proliferation of yeast, aroma components, and the amount of various organic acids produced?

In addition, in terms of cooperation with Shuzo, the vibrator was installed on the fermentation barrel of Dassai on 2020/11/18, and the music for Shuzo was the new song " Symphony " composed by Asahi Shuzo in cooperation with Japan Century Symphony Orchestra and ONKYO Dassai~grinding~migaki ". The brewed sake will only be sold at the concert of "Symphony Dassai ~ Ma migaki ~ Five Senses Taste わうコンサート" held on February 27-28, 2021. (ㄜ... President Hiroshi Sakurai will be appointed as the chairman of the Japan Century Symphony Orchestra on 7/1/2021)

Next, I collaborated with Sanfangju from Tokushima Prefecture on "Gazhen Wine プロジェクト"壱"ICHI". Magong Du of Sanfangju likes music very much, and plays the guitar himself. There are equipment for live music performances in the liquor store. Brewing sake. This time, the vibrator is to be installed on the 4500L brewing barrel made of enamel. Because the barrel is very old and there is no design drawing or anything, the detailed dimensions are re-measured to adjust the installation specifications of the vibrator, so that the resonance effect can be achieved. Uniform and stable.

However, there are many specifications of wine, which one should you choose for trial brewing? A brief investigation of the taste changes after adding vibration to the existing wines of the polished rice Buhe 40.50.60.70 found that the wine quality of the polished rice Buhe 70 pure rice wine improved the most. In the end, 70% of Yamada Nishiki, a total rice volume of 600 kilograms, is used with Tokushima yeast to make a quick-brewed wine brewer, and then it is divided into two barrels to make wine mash, half of which is added with Mozart, and the other half is not. Add vibration.

The mash on both sides had significantly different results. In the early stage of fermentation, the mash of the Jiazhen version is very lively, the dissolution, saccharification and fermentation progress of the koji are faster, the taste is stronger and the rice taste is stronger, and the days of fermentation to the tank are shorter. If you want to compare the difference in body with and without the addition, you can buy it from Makuake's crowdfunding project , which has a more detailed fermentation progress record on the page.
