Abstract: The present invention provides a pour-over coffee replication system, comprising: an electronic scale, a thermometer, a mobile device, a cloud server and a coffee machine. During the process of making pour-over coffee, the electronic scale is used to obtain the weight time sequence of the coffee beans (powder) as well as the hot water, the thermometer is used to obtain the temperature time sequence of the output hot water. The mobile device integrates the data and converts all the data into a digital coffee making prescription, and uploads it to the cloud server for storage, so that one or more than one user can access from anywhere or at any time. After the coffee machine is connected to the cloud server, the digital coffee making prescription can be easily obtained, and the coffee machine can automatically replicate the process of making pour-over coffee and produce coffee having the same flavor and taste as pour-over coffee.
