You need to grind the coffee with a quality burr grinder. The grind should be reasonably fine. How fine? This is different with each Vacuum Pot. You’ll need to experiment. Start by grinding as you would for auto-drip. If the water rushes through the coffee and the coffee is thin and weak, grind finer. If the coffee clogs the brewer, grind coarser. We recommend 8 grams (0.28 oz or about one rounded tablespoon) coffee per 4 oz of water.
Fill Bottom Globe with Water and Put on the Heat Source
If you’re using an alcohol burner (or the like) you should preheat the water in an electric kettle (or something similar) to decrease boiling time. If you do this, be very careful when handling the brewer as it will become very hot quite quickly.
Assemble the Vacuum Brewer
When the water starts to near a boil (forming small bubbles) put the top globe onto the bottom globe. Fairly quickly after you have sealed the brewer, water should start making its way to the top vessel. Allow this to continue till vapor starts to escape the bottom vessel and the brewer begins to gurgle.
Stir in the Coffee
Add your coffee and stir until there are no dry grounds. This step should take approximately 10 seconds.
Wait Then Stir
Allow the coffee to brew for 30 seconds then gently re-submerge the grounds.
Remove Brewer from Heat
Remove the brewer from the heat source and turn off (or extinguish) the source. This should be about 50 seconds to a minute after you initially added the coffee. Be careful and use hot pads.
Watch the Extraction
You will see coffee begin to extract back through the filter into the bottom globe as the brewer cools. After the draw-down begins, give the coffee one gentle stir to create a whirlpool in the brewer. Once the water stops pulling back through the coffee and the filter, remove the top globe and pour the coffee into cups. Again… be careful and use hot pads.
