The present invention provides a beverage machine that heats up water in the upper water chamber(s). The water has direct contact with an electric heating system and the heated water flows by gravity and being distributed by a pour over system into an underlying filter basket. The hot water chamber comprises a sensor for water temperature. Once the water reaches an optimal temperature, a motor and gear system would drive a valve open and allow the heated water to flow into the underlying filter basket. The present invention allows certain amount of water to be heated up in individual batch, thereby making it easy to manage water temperature in every batch.
