Yama
Vacuum Brewing Pictorial
(Cona and Bodum Santos Too)
Here is a step by step pictorial to brewing
in the Yama vacuum brewer. Here I am using the 5 cup model with the
Cona glass filter rod. This is a great day-to-day, low cost vacuum brewing
setup. Undoubtedly, if you brew this way you will find your own method
to brew, but here is the way I get great results...
|
okay, here we are ready to go. on a gas stove, you do not need the wire grind between the yama bottom bowl and the burner. the top bowl sits in the stand |
it is so much easier to use hot water. preheat good spring water or filtered tap water. fill to the desired line. i feel that making full pots (ie 5 cups in the 5 cup model) is best. |
once the water is in, seat the top bowl on with a slight twist. if the seal between top and bottom is not good, no syphon or vacuum action is possible. |
make sure the filter is in place and add the coffee to the top. in this demo, i am not using the yama filter cloth-disk assembly, but instead the glass filter rod. both work well. |
okay, we are ready to brew, just turn on the heat... |
okay, the heat is put on the lowest setting, or nearly the lowest. if you want to brew starting with cold water, you will need a bit more flame, but never on high! again, i think it is far better to start with hot water, which means the syphoning to the upper bowl is immediate. |
to stir or not to stir? You simply don't want dry grounds to form "islands" that
fail to infuse with the hot water, but frankly a yama will tend to syphon
so vigorously that it will roil all the grounds into the brew. |
stirring does help to break up the crust on the top ... you simply want the grounds to mix throughly with the water. don't stir too much ... like 5 times. if you use the cona rod, don't knock it as you stir. |
the water has syphoned upward. in this demo it took under 1 minute. there
is always a bit of water that remains below, this is normal. you may
see the "boiling" action in the top funnel, but this is pressure
action, not actual boiling; vacuum brewing never boils coffee, it's just
not possible to exceed 212 f. |
steep time? keep the flame on the lowest setting. while you want a total of about 4 minutes steep time with brew methods, i get best results with leaving the yama (or bodum or cona) to steep for only about 1 minute. why? well, it has already steeped 1 minute as the water syphons up, and it will be another minute before it is all vacuumed down. |
when you are ready to start the vacuum, turn off the flame. usually, i move the brewer off the burner i heated it on, because residual heat slows the vacuum process |
we are about half way in this picture. ideally i like it to vacuum down in 1-2 minutes. |
at the end of the vacuum |
remove the top funnel, and place it in the stand. do not try to heat the coffee at this point, trying to keep it warm. that ruins it. |
enjoy the results! |
