Topic: Vintage Vac Brewers with glass filters (5 msgs / 199 lines)
1) From: Gary Raabe
Hello All;
This is my first post.
(It is wonderful to have a great knowledge base to draw upon.)
 
I need help with old Cory and Silex Vac pot brewers with glass filter rods.
I cannot get a good draw back. This seems to be caused by a grounds dam plu=
gging up the return path for the coffee.
I am thinking it is caused by inconsistent grind. I have a Kitchen Aid Pro =
Series and a Rancilio Rocky grinders. I have tried both and neither seem to=
 give me a "powderless" result. I have tried coarser settings but I still g=
et too much powder.
I know I am getting a good seal because I have to reach in and try to offse=
t the filter rod from side to side to try to release the vacuum before I ca=
n get the filter out or the top funnel off. Then of course, all the coffee =
and grinds go into the bottom pot and I have to pour it through a paper fil=
ter (yuck)
Any suggestions, tips or tricks would be appreciated.
Thanks,
Gary (Cincinnati OH)

Hi Gary,
Try the Rocky at its most open point - say "50" on the dial...  That's how I
do mine for Cory Vacpots when using my Rocky...
Personally, I have a 40's Cory grindmaster that puts out a good coarse grind
- and I never get a stall in my vacpots.  Same is true with my zass, but at
times I have had a stall due to fines...
Have you done a vacpot with the "coarsest" grind from your Rocky?
Just a couple ideas....
Brett

Gary,
     If you are getting dust with your Rocky, the burrs are dull and  
need to be replaced.

I know nothing about Rocky. It sounds like you have an excellent vacuum pot=
.
To get rid of any fines, whatever their source, grind into a flour sifter,
sift the fines through onto a paper towel and dump the coarse grounds into
the top of your vac. pot with the stem in place and ready to brew coffee.
Boil water in a tea kettle and remove the kettle from heat. Pour 1/2 inch o=
f
the hot water in the bottom half of the brewer and assemble the two halves.
Place the brewer over low diffused heat until you see the water starting up
the stem.
Pour hot water from the kettle, fill the upper half and lightly stir the
mixture a few times in 3-4 minutes. The finale is to stop the heat and watc=
h
the show.
With the exception of sifting out the fines and the long brew time, I brewe=
d
coffee for the folks that way dozens of times. They loved it. I didn't- too
hot and too weak for me. I crunched beans for a cool 100% extraction at
98.6F!

I had that same problem. I've not used a Silex, but my first vac pot was 
an old Cory stainless steel electric vac pot with a Cory glass rod. I 
had all sorts of stall problems with it. By doing several experiments, I 
found the best grind setting and way of grinding with my Zass to give 
the biggest percentage chance of not stalling. It is the corsest setting 
I use on the Zass (but not as course as the Zass can go). I would say 
50-70% of my pots didn't stall doing it that way.
One thing I ended up doing was taking some BBQ grill tongs and locking 
them around the top part of the glass rod, then move it back and forth 
while gently pulling up. Usually there is enough suction that it 
wouldn't pull out, but doing that would loosen up some of the plugging 
that happened and I rarely had much grounds in the bottom after I was 
done. One or two times the rod pulled out enough to let a good amount of 
grounds through, but that was rare.
The other option I would suggest, is just find and get a cloth filter. 
When I bought my Yama, it came with them, and I could use my Cory with 
those with no worries of stalling, even at a finer grind.
Oddly, I tried the glass rod with my Yama and it works without a hitch. 
I think, but don't know for sure, that the rod sits differently in the 
Yama, I'm thinking, so there is less contact between the bowl and the 
rod, and maybe higher up on the rod where the groves are more 
pronounced, that it works better. But I rarely have a stall in the Yama, 
unless I use the preheat the water first method, sometimes (like today) 
that brings out the BBQ tongs again. But if I heat it up in the pot on 
the stove (about 30 minutes) I've not had one stall or even that close 
to one, even though I use a finer grind than I did on the Cory.
<Snip>
It's caused by too much fines in the grind, which does result from an 
inconsistent grind. The fines go into the groves and plug it up, where 
as courser grinds are held back. And, on the Cory's at least, I think 
the bowl hits the glass rod groves lower down where they are more 
shallow, and thus more likely to plug up.
Welcome to the list. :)
