insert the upper part on the bottom bulb, make sure it's securely and evenly in place and put the entire assembly above your heat source.
Syphon coffee was invented in the 1840s. It’s been refined many times, but a few principles stayed: Syphon produces a delicate taste and tea-like consistency.
How to brew:
After soaking the filter in a warm water for 5 minuter, put it into syphon's upper glass.
Fill the bottom bulb with 450 grams of hot water.
Soon, the water in the bulb will begin boiling and rise up into the upper glass. Once the water has moved fully add your coffee, and gently submerge.
After one minute remove your siphon from its heat source and wait to draw downward into the bulb.
