I was the one that mentioned my wok roast didn't stall in my vac pot. I
agree with another poster, it seems perhaps some cory rods just rest
differently and are more prone to stalling than others. When I first
obtained my vac pot back around Christmas, I had a lot of problems with
stalls. Essentially, I couldn't get a drain time under 17-20 minutes and
sometimes it just didn't drain at all.
I tried various grind sizes and did this and that based on suggestions I
received from the list, but nothing seemed to help. Finally, it seems a
combination of things helped to get where I was at least having decent
drop times a good percent of the time, but gave up trying to get them
most of the time. At some point, I'll get some more cory rods off ebay
and see if that will help.
What I did do was the following:
1. I examined my Cory rod and noticed a seam that seemed a bit higher
than it should be. My hunch was that it was raising the rod too high,
and allowing more finer particles into the cracks of the glass rod and
so clogging it up. So I took a file and worked on filing the seam down
to a smoother and lower level. That seemed to help.
2. I worked on my grind more. I was and am using a Zass, and I tried
various settings at 1/4 turns from drip level to press pot grind, based
on what I had read were the usual settings for that on a Zass. Later, I
went back and did some finer settings, going 1/8 turn at a time. That
time, I finally got my total from water coming up till the last bit went
down to under 10 minutes. Ironically, though many seem to find it works
best close to drip, for me it seemed to work best just 1/8 turn away
from press pot grind. I have no idea why, I just know on mine it does.
So I would suggest when you go to experimenting with the grind, also
make sure you do some fine adjustments, as the perfect grind size for
your grinder and glass rod may be a fairly narrow window and adjusting
too much can cause you to miss it.
3. And this one probably won't apply to you since you are not using a
Zass, but the biggest "fix" was in the way I was grinding with the Zass.
I was grinding by holding it on a counter and turning. I figured out
that this method didn't offer much in the way of "shock absorber" to the
top of the bracket that held the burr shaft in place, and caused some
slight rocking, enough to produce more dust to clog the filer with. When
I went to holding the Zass between my knees and grinding that way, there
was a huge difference in how well the vac pot did. That alone was
probably the biggest factor, getting the total time under 8 minutes on a
good vac pot brew. What that does tell you is simply that the quality of
the grind plays a huge part in how well the vac pot with a glass rod
will avoid stalling. If your grinder simply isn't capable of a certain
level of consistent grind, it may be that you will have a hard time
getting a stall-less vac pot brew. Just minor movement in the burrs or
imprecise construction can create too much dust to avoid stalling.
Now, what I wish they did make was a swiss gold filter for vac pots! Now
that would be cool! Something like this 2 disk thing I have for vac pots
(but it seems to stall too) but made out of SG instead.
Oh, and I do have a plastic pour over for a thermos and a swiss gold #4
filter for it, as well as a SG one cup. I like it fine, and as some have
said, the amount of coffee and grind size might need to be different to
achieve the same results as the one cup. However, I hardly ever mess
with that, I like both as they are and only notice maybe a slight
difference between the two. However, I also like to use paper filters,
but stick with the ones Tom sells. I've been using the Filothropia (sp?)
filters which I like, they don't seem to impart paper flavor to the drip
brew. They probably do filter out more oil than the SG does. However,
Tom is out of those now, and so I have the aroma browns on the way, I'll
see how those do. I guess I like convenience a lot too, and the coffee
that comes out of it with my Presto is outstanding, no matter what brew
method I use, so I like them all and switch between this one and that
based on how I feel at the time. Everyone's taste is a big different I
suppose, and I'm a variety kind of guy!
