SIPHON / VACUUM POT

The siphon (or vacuum pot) is one of the most theatrical and precise ways to brew coffee, blending science and craft into a truly captivating experience. Using vapor pressure and vacuum suction, the siphon brews coffee in two chambers, allowing for full immersion and a clean separation of grounds.

What You’ll Need:

  • Siphon brewer (tabletop or stovetop)
  • Butane burner or heat source
  • Medium grind SZNS Coffee
  • Stirring paddle
  • Scale
  • Timer

Preparation:

  • Ratio: 1:15 (e.g. 25g coffee to 375g water)
  • Add water to bottom globe
  • Place top chamber loosely until water boils

Brew Process:

  1. Heat water in the bottom globe until it rises to the upper chamber.
  2. Add coffee and stir to saturate.
  3. Brew for 1–1.5 minutes.
  4. Remove the heat source.
  5. As vacuum pressure drops, brewed coffee filters back into the lower chamber.
  6. Remove the upper chamber, stir coffee, and serve.

Roaster’s Tip: For the best results, use freshly ground coffee with a medium to medium-coarse grind — too fine a grind can lead to over-extraction and bitterness. Maintain a consistent water temperature (around 200°F) and ensure the water in the lower chamber is just reaching a boil, not bubbling too aggressively.
