Subject: Cory brewing time
With a Cory 8-cup vacuum pot [DRU/L], what should be the approximate time
from the start of the coffee return to the bottom pot until it is complete?
This one seems awfully slow -- like 20 minutes. Is slowness a result of a
poor seal or coffee ground too fine?

After the recent death of my Krups Moka Brew I went with the Yama Vacuum
Coffee Siphon, 8 Cup. (their measure, mine is closer to 6 cups). From
the time I remove the fully brewed product from the stove top, until the
return is complete is less than two minutes and probably closer to one
minute. It is fast enough that I have not timed the process.

BUT, and a major but, I was not totally satisfied with the stock setup,
would I be in this forum if I were?, and set out to improve upon it.
My first change was the filter. I use a very old Cory glass rod,
purchased via eBay. ignoring the middle steps, I now use the Cory rod
with percolator filter on the bottom (spring, ball, and chain through
the center hole), very fine ground coffee and my results are
consistently great.

Are you sure it is a Cory? The only glass filters I've seen like that are
the Silex Lox-In filters.

In consideration of the state, or lack there of, of my memory and the
purchase having occurred more than 7 years ago, I yield to your much
more likely accuracy. However, the results are still quite acceptable.

It should be more like one minute than 20 minutes. Remember, the total
brewing time should be around 4 minutes.

It is unlikely that the coffee is simply too fine. It is even less likely
that the seal is defective - if it were, the coffee would never go down
(or up).

Most likely, you have excessive dust in your grinds. When my vac pot
stalls, it tells me that I need to clean out my grinder, because excessive
dust has collected. I use a brush, a vacuum cleaner, or canned air,
depending on my mood.

Try using the pot without any grinds, and see what happens. If the water
stalls up top, you can eliminate the grind as a problem.

If you suspect a leaky seal, paint the seal with soapy water as the hot
water rises. At that point, you might see soap bubbles coming out from
where the seal is leaking.

What kind of a filter are you using? I use a Cory rod in my Silex, and it
works very well. It is possible that your filter is clogging due to a
reason other than a grind which is simply too fine.

OK, I tried it with plain water. It came down in less than a minute after
going into the top pot. I have been using a whirly grinder for it so that I
wouldn't have to change the espresso setting on my Gaggia MDF. However,
I'll use the MDF to grind in the morning and see if that makes the
difference. Thanks.

I'm surprised, but not too surprised. IME, the consistency of the grind
is more important than anything else when it comes to clogging a filter.
I grind fine for vac-pot and french press, and seldom have problems.

Let us know how it works out. I expect that you will get good results by
using a good grinder.

With coffee ground at 12 on my MDF, the Cory brewed 6 cups for two minutes
and returned it to the bottom pot in 2:31 minutes. That is compared to a
return time of nearly 20 minutes yesterday with coffee ground in my Krups
whirly grinder. The coffee is darker and still very smooth and clear.

That sounds just about perfect.

One thing to keep in mind is that the water needs to boil in the bottom
for at least 30 seconds or so after the majority of it goes north. That
is because any residual air in the bottom needs to be driven out by the
steam. The way vacpots work is that the steam condenses into water after
the pot is taken off the heat. The water droplets take up a LOT less room
than the steam, reducing the pressure in the bottom. Any resudual air
will expand when heated, and contract when cooled, but the magnitude is
much less, resulting in less suction.

I should add that the coffee tastes fine, except that it is not as warm as
it could be after that much time.

I am just using the Cory glass rod. There were a package of 3.5" filters
included, but I have never used them -- didn't know if they were even for
this model..

What are the results if you use no coffee? I would think if it acts the
same you don't have a grind problem.
