Topic: Bodum vac pot solution (58 lines)
1) From: Stan Armstrong
A few days ago some of you were discussing vacuum pot brewing, =
specifically
a Bodum. I tried to respond at the time, but my posts were being =
rejected as
oversized, despite the fact that some of them were quite short. I think
(hope) that problem has been solved now, so here goes.
I, too, have an electric Bodum vac brewer, the Mini Santos. I have been
using it for two years with two modifications that give me complete =
control.
First, I have disabled the auto-shutoff switch. This is easy. Just pop =
off
the bottom and route the power to bypass the switch (no wires to cut;
nothing to solder). Second, I run through a Variac with a voltage meter
attached. Granted, this is pricey, but I had the Variac w. meter on =
hand.
Finally, you need a good digital thermometer, the probe of which will =
double
nicely as a stirring rod.
Here is my current brewing procedure:
1. Grind quite fine in a Zass grinder driven by a 3/8" electric drill. =
(The
grind is almost as fine as I can make it by hand-tightening the control
ring.)
2. Heat the water to 185° F with the Variac at 130+ volts.
3. Reduce the Variac to 90 volts.
4. Insert the top with coffee into the base.
5. When the temp reaches 199° F, reduce the voltage to 45 volts.
6. Brew with stirring for an additional minute.
7. Turn off the Variac.
With a full pot (5 cups+) these settings keep the brew temp constant. =
Other
brew sizes require a slightly different voltage to keep the temp =
constant.
If you don’t want to stir while brewing, you may also want a slightly
different voltage.
Now if only my memory for tastes were well enough educated, I could
experiment with all sorts of brewing time/temp variations.
Regards,
Stan
