How to Make Syphon Coffee

What you need

• syphon coffee maker with bottom chamber
• syphon coffee maker upper chamber
• metallic filter holder
• paper filter
• burner or heat source
• coffee grinder
• scale
• timer
• cup

Method

1. Remove the upper chamber from the syphon, then pull the chain hook and carefully reach inside to unscrew and remove the metallic filter holder

   Handle glass chambers gently throughout assembly and disassembly

2. Place a paper filter into the filter holder, screw the holder back together, lower it into the upper chamber, and hook the chain to the bottom of the tube so the filter covers the entire tube opening

   Full coverage of the tube opening is essential — any gap allows coffee grounds to pass into the bottom chamber

3. Pre-wet the paper filter with hot water to remove any paper taste, then discard the rinse water

4. Pour 300 ml of water into the bottom chamber, place the burner underneath, and light the burner to begin heating

5. While the water heats, weigh 20 g of medium-roasted Colombian coffee beans and grind them to a medium-coarse size — slightly coarser than a V60 or Chemex grind

   The ground particles should appear visibly coarser than pour-over but not as coarse as French press

   Expert tipFruity coffee beans are recommended to highlight the clean, aromatic character the syphon produces

6. Once all the water has risen into the upper chamber, reduce the heat to stop rapid boiling and bubbling, then wait for the water to calm and settle

   Adding coffee to violently bubbling water disrupts even extraction; patience here improves the cup

7. 0:00

   Add the coffee grounds to the upper chamber and stir gently until all grounds are fully immersed in the water, then start a 1-minute timer

8. 1:00

   At 1 minute, remove the heat source from the bottom chamber, then stir the coffee in a circular motion to create a spinning vortex; stop stirring once the coffee begins dripping down and let the vacuum draw it fully into the bottom chamber

   As the lower chamber cools, it contracts and creates a vacuum that pulls the brewed coffee through the filter, leaving grounds behind in the upper chamber

9. Once all coffee has been vacuumed into the bottom chamber, remove and set aside the upper chamber, pour the coffee into a cup, and allow it to cool before drinking

   The coffee exits at near-boiling temperature; waiting for it to cool is recommended for the best tasting experience

Why this works

The syphon exploits thermodynamics in two distinct phases. Heat forces water up through the filter into the upper chamber, where immersion contact extracts flavor from the grounds evenly. Removing the heat causes the lower chamber to cool and contract, generating a partial vacuum that draws the brewed coffee back down through the filter under controlled pressure. This two-stage movement — upward immersion, downward filtration — agitates the bed thoroughly and then clarifies the liquid cleanly, producing a bright, sediment-free cup that retains noticeable body.

Where beginners go wrong

1. 1

   Coffee grounds appear in the finished cup

   Confirm the paper filter is properly seated in the filter holder and that it covers the full tube opening before brewing; any gap lets grounds bypass the filter

2. 2

   Water is still vigorously bubbling when it is time to add coffee

   Reduce the heat after the water has fully risen and wait until the turbulence subsides completely before adding grounds

3. 3

   Cup has a papery or cardboard taste

   Always pre-wet the paper filter and discard the rinse water before adding brew water to the bottom chamber

4. 4

   Coffee tastes flat or harsh when sipped immediately

   The brew exits at boiling temperature; allow the cup to cool to a comfortable drinking temperature before evaluating flavor

What you should taste

A well-brewed syphon delivers a clean, full-bodied cup with enhanced aroma and no sediment
