Vacuum pot
The preparation of coffee in a vacuum pot is complicated, but it is an interesting process. Vacuum pot has two chambers. Fill the lower chamber with water, which is heated to boiling. The upper chamber contains the coffee grounds and these are placed on top to form a seal. The steam starts to accumulate in the lower chamber and pushes the water through the tube and filter into the upper chamber. Then the infusion is left to infuse.
Once the vacuum vessel is removed from the heat, the steam cools and condenses back to water, which creates the vacuum (and the name!). This vacuum draws the coffee from the upper chamber back through the filter and into the lower chamber, leaving the sediment trapped in the upper part. The coffee can then be poured from the bottom.
