Coffee brewing may look like a scientific experiment. This is the case. But don't worry, the siphon is an extremely simple device invented at the beginning of the 19th century. Technica combines beautiful workmanship, minimalist design and amazing functionality! The syphon works using the basic laws of physics. Fill the lower chamber with water which, when heated, flows to the upper chamber with ground beans. After a few minutes, disconnect the heat source and your coffee will flow through the filter into the lower chamber. It's ready! Capacity: 240 ml The set includes an alcohol burner.
