代表銘柄	今代司、錦鯉
酒造概要	今代司酒造では、酒造りを見直したいという想いで、2006年からアルコール添加を一切行わない全量純米仕込みに切り替えました。 酒どころ新潟において戦後最初の取り組みでした。アルコール添加やその他副原料を使わないということは、酒造りの最後に味や香りを調整することができないということです。 それゆえ、最初から最後まで、酒造りのすべての工程が緊張感あふれる真剣勝負となることは、全量純米仕込みにするメリットでした。純米大吟醸、純米吟醸、純米酒と、純米だけを作る純米専門の酒蔵として、個性を大切にした酒造りに取り組んでいます。

■ Overview of the Functionality of “SHIMENAWA”

“SHIMENAWA” is equipped with the following basic functions to protect your valuable sake brands.
1　Authentication function
The unique ID recorded on the NFC tag attached to each product (physical asset) is securely linked with digital information —detailing "when," "where," and "who brewed" the sake— recorded in a tamper-proof manner on the blockchain to prove the sake brewer or brewing company.
2　Open Seal Detection Function
From the viewpoint of food safety, the system can prove that the sake is unopened and that “the moment you open the bottle” is shown on the map in an entertainment-like mechanism. This function also provides data on when, where, and how long the sake has been opened (consumed). Breweries can utilize this data for intelligent management.
3　Genuine product management function (linking of shipping destination information)
Sake breweries can use NFC tags to link the unique ID attached to each sake to the destination information and manage it in a database. This function can be used to deter unauthorized diversion of sake, and can also be used to identify trends in the origin of illegally diverted sake for use in distributor management.
4　Fan Marketing Function
A special screen is displayed only after the sake is purchased and opened (purchased) and registered, and it is possible to promote initiatives such as customer loyalty through a function that leads to a limited (private) website and the receipt of a non-fungible token (NFT).
5　Design and content management functions ＜New＞
From March 2025, a new function has been implemented that allows user companies to create, change, update and manage the screen design (logo, colours and display text) and content of the SHIMENAWA application in their own way. This enables a more unified expression of the company's own brand.
