Making coffee can seem like a science experiment. It is. But don't worry, the siphon is a very simple device invented in the early 19th century. Technica combines beautiful craftsmanship, minimalist design and amazing functionality! The siphon works according to the basic laws of physics. Fill the lower chamber with water, which flows into the upper chamber with ground beans when heated. After a few minutes, disconnect the heat source and the coffee passes through the filter into the lower chamber. It is ready! Capacity: 360 ml. An alcohol burner is included in the set.
