1. |
Measure water
into the lower globe (decanter) using an average coffee cup. Count how many
"cups" are needed to fill the decanter to at least 1/2 full and no more than 7/8
full.
[Note: A "cup" in the coffee world is 5 fluid ounces] |
|
 |
2. |
Place the lower decanter on the
heat source over high heat. You can place the decanter directly on a gas burner or
an electric heating element made specifically for your vacuum pot - but if you are using
a household electric stove, use a wire trivet or heat diffuser to avoid damaging the glass.
[Obviously, this does not apply to a metal vacuum pot] |
|
 |
3. |
Position the filter in the upper
globe, locking in place if necessary. There are a huge number of different filter
designs, some with clips or spring locks, and some which require paper or cloth filters. |
|
 |
4. |
Measure ground coffee
(medium-fine grind) into the upper globe, using two level tablespoons of coffee for each
"cup" used in step 1. For future pots, adjust the amount of coffee up or
down to suit your individual taste. [Avoid grinders which produce a lot of dust, as this
may clog the filter and may produce excessive sediment in the brew] |
|
 |
5. |
When the water in the decanter
has begun to simmer, position the upper globe (funnel) in place on top of the decanter and
press down firmly to form a good seal. [If using a gasketless vacuum pot, moisten the
ground glass lip and place the upper globe in place]. |
|
 |
6. |
As the water heats, vapor
pressure will force the water up the funnel tube into the upper globe. When about
half of the water has risen to the top, turn the heat down to medium and give the coffee
in the upper globe a quick stir to ensure that the grounds are well distributed. |
|
 |
7. |
As soon as the water level in
the decanter reaches the bottom of the funnel tube, air and water vapor will rush up the
tube causing the coffee in the upper globe to "gurgle". Allow the coffee to
gurgle for at least one minute [some people let the coffee gurgle for 1-3 minutes. Longer
gurgling times will produce a stronger brew]. |
|
 |
8. |
Remove the pot from the heat.
As the water vapor in the bottom condenses, a vacuum is formed which will siphon
the brewed coffee back down into the decanter. [If the coffee fails to come down,
make sure that: (a) the coffee is not too finely ground; (b) the seal between
the top and bottom globes is secure and air-tight; and (c) you allowed the coffee to
gurgle at least one minute - brewing less than a full pot will require longer gurgle
times.] |
|
 |
9. |
When all the coffee has been
siphoned down into the decanter, remove the upper globe by grasping the decanter handle
and pressing against the upper globe with your thumb to break the seal. Carefully
remove the upper globe and set aside. |

10. |
Serve coffee. Enjoy. |
