Mill the field's rice
Rice from the named field is milled and logged.
Field to bottle
From a valley paddy to a sealed bottle.
Sake is labelled by region and brewery with no record of the rice field or the ageing conditions, and aged sake claims are hard to check.
Each cask carries its rice field, brewing date and ageing room, signed by the brewer and checked by the buyer.
Brew the cask
The cask is brewed and the day is recorded.
Rest in the room
The ageing room and temperature are logged.
Bottle with a code
The cask is bottled with its record code.
