A brewer's son who learned to code.

Kura Sake comes from Niigata. The son of a family that runs a small brewery started it with a programmer who made stock-keeping software for sake and shochu makers. Neither has used a blockchain before, and Canton with Daml is new study for both.

• ValleysNiigata and Nagano, Japan. We spend brewing season inside kura with toji and their assistants.
• Where it standsA prototype in testing. No real cask has been recorded on it for a buyer.
• Honest footingDistributed ledgers are new to us. We read the Canton and Daml material, test small pieces, and tell each brewery this before anything is agreed.
