Topic: Vac pot problems (17 msgs / 349 lines)
1) From: Ken Merrell
Hello all,
I've search the archives and still can't come up with an answer.
I have a Bodum Vac pot, the problem is it takes forever to head south.
I've tried different water temps, different grinds, lightened up the 
spring.  It can take 5-10 minutes or more to complete the process.
I preheat the water with an electric kettle to boiling, pour it in the 
bodum bottom pot, apply heat from the gas stove (medium to low) until I see 
some boiling beginning again, attach the funnel.  The water makes a fast 
trip up north and I leave it on a low heat for 60 seconds, then remove it 
from the heat and then wait forever for it to fill the bottom, sometimes it 
stops altogether.
Please help me, I drinking a lot of over extracted coffee.
Thanks,
Ken

Have you tried to adjust the grind?

3) From: Ken Merrell
I think I have the problem solved.  Sorry to bother you all.
I got rid of my Melitta Burr Grinder and picked up a Solis Maestro.  My 
first 2 pots at a slightly below medium grind came out absolutely perfect!!!!
The grinder made all the difference in the world, I guess I just didn't 
believe it.
Thanks,
Ken

Hi Ken,
First thing that comes to mind is that the seal is faulty between upper 
and lower chamber.
I have a bodum vac pot also, grind very fine, and have no trouble. This 
unit depends on the bottom pot cooling, creating a vacuum that will suck 
down the liquid from above. No seal, no liquid transfer. Gravity alone 
will not work.
Hope this helps,

I just went through this. Here's what I do -- it seems to work:
1) Go through the usual process (put in boiling water, put the bottom 
part on the heat, put in the top part w/ grounds)
2) After the water goes North, give the grounds a stir to completely wet 
them -- don't touch the grounds thereafter
3) When "enough" time has passed, give a brief jolt of extra heat, then 
turn off the heat
4) Keep the pot on the still warm burner (obviously only works for a gas 
range)
Since I switched to this process, I haven't hit a stall yet (after 
struggling with stalls multiple times).

Glad to hear it.

Yes, I adjusted the grind so many times, the Melitta just couldn't handle 
the job, it was too inconsistent.  The Solis Maestro is working great!!
Thanks!!!

Glad to hear you fixed it :)
I forgot to mention that I grind fine for the Bodum, but with my Mazzer 
Mini. That works pretty well too.
Keep on cuppin :)

Ken,
     What kind of grinder do you have?   If it produces dust, it doesn't 
matter what your average grind is, the dust will plug the filter.

Agreed.  Likely your grind is too fine.

Glad to hear you solved it.. If it happens again, try using a cool, damp 
rag on the bottom pot. It will create more of a vacuum. Of course, the seal 
is important. I usually wet the rubber before I mate the pots...

I agree,   I find it frustrating that people will come to the list and =
ask questions and after they hear a chorus of agreement on the 
importance of a good grinder they say that they can't see spending a 
few hundred dollars for a grinder but go ahead and spend more on 
various roasting machines and brewing gadgets.

Us newbies are always looking for the cheap way out (at least me).  I can't 
tell you how many times I adjusted the grind on that Melitta grinder only 
to have failure.  I DID see the importance of the grind but I couldn't see 
the importance of the grinder.  Now I do!!!  Big time!!! I guess that's how 
we move from being newbies to veterans.
Thanks for your patience in understanding our frustration too and helping 
us move to the next step!!!  I can now join in the "chorus of the 
importance of a good grinder" only to be frustrated at newbies not 
believing me!!!  Its a circle!!!
Thanks again for the education this list provides!!!

RIGHT ON JIM!!
I put on my Dr.Crema hat again last week and visited a guy (not on our list) who has an Isomac Amica, (wanted to try that puppy out!), a Hottop and he was having very poor performance.  On a whim, I brought my Zaus because he didn't say what grinder he had.  I also brought some of my own roasted beans just to make sure.  He was using a Whirly Grinder!  So, I let him pull 3 shots with his grind and talk about a thin over extracted mess!  No crema, tasted like church coffee on Sunday night after it had been sitting all day!  I whipped out my Zaus and he scoffed at me!!!  He said, "I can't believe that you think a hand grinder can be better than my new electric! (My Zauss is 20 years old and it shows on the outside.)  I told him if I had known I would have brought the Mazzer!  I pulled a dazzling shot of his coffee with crema and a brew that was sweet and as smooth as silk!  He was shocked and very upset at himself for not getting a better grinder.  Spend your bucks on a Grinder
 !!  I
 couldn't believe this guy.  He had over $1,000 bucks in a roaster and machine, but spent less than $20.00 on the most important part of extraction!  It is too bad Ken bought a Maestro.  He is in for about 6 months of good espresso before his $100.00+ investment bits the burrs!  If you are doing espresso, get a good grinder with replaceable burrs both top and bottom!  As Mike McKoffee has shared, his upgrades were much more expensive than if he had just got the Rocky to start with.
