Topic: Les, Got a Preferred Technivorm Method? (12 msgs / 281 lines)
1) From: Bob Hazen
Les,
Would you mind sharing your Technivorm method?  I appreciate your insight 
into roasting and I bet you have some insight to the Technivorm as well.  Do 
you use Tom's recommended "hold back and stir" approach or just let 'er rip? 
Or?
I use a Technivorm quite often.  I usually make a little more than half a 
pot and leave the flow restrictor full on.  About a minute into the cycle, I 
use a spoon to push any floating coffee down into the soup.  It seems to 
work pretty well.  I use a coarser grind for a full pot due to the longer 
brew cycle; typically 9-10 on my MDF for a half-pot and 12 for a full pot. 
Adjusting the grind works better for me than adjusting the flow.
Interested in your thoughts....
Bob

I follow Tom's method.  I have expermented with some others, but it seems to
make the best brew.

Here's my variation on it. I make a full pot (it gets consumed pretty  
quickly).  I preheat the carafe with very hot tap water and then empty  
it out after a minute. I leave the flow restrictor in the closed ("X")  
position until about 2 c. of water has dripped into the filter basket-- 
I begin to stir when 1 c. has dripped in. When the basket is nearly  
full, I stir once more, open the restrictor halfway, and cover the  
basket with the lid.  When half the water has dripped into the basket,  
I open the restrictor all the way; when the tank is empty and the  
coffee has stopped dripping into the carafe, I close the restrictor,  
pour the first cup(s) and immediately cap the carafe and dump the  
spent grounds.

Sure am glad this subject came up.  Maybe you guys can tell me what's going on.
When I try Toms method, that is stirring the grounds at the start with the drip
cut off I have problems. Here is my method.  Please tell me what I'm doing
wrong. I grind 50g of coffee, fill the water container to the top.  Then close
the drip valve.  Start the brew, wait until the water wets most of the ground
and then stir.  After stirring I open the valve to full open. When the
container gets down to about 4 cups the filter is just about to overflow.  So I
turn off the brewer until the water level goes down then turn it back on to
finish. I thought my grinder, a Kitchen Aid Pro Line, was giving me to much
powder.  So I bought a Mazzer Mini.  Yes, a Mazzer Mini.  Guess what, I still
have the same problem.  I know I really didn't waste the money for a Mazzer,
but I'm really discouraged. I have tried grinding all the way up to big chunks
and the same thing.  The only way I've found to get around the overflow problem
is to leave the valve open, then when the water get over the grounds.  Gently
push the floating
ground under.   This way the water level only goes about half way up
the filter. So my question is, why do I get an overflow if I stir the ground
early with the valve closed? If it is to much powder, is my Mazzer defective?

John,
I would say grind a little coarser, but my god you have a Mazzer making big 
chunks, there are only 3 possibilities, grind too fine, filter too 
restricted, machine boils water too fast.  Take your pick.  I'm guessing you 
need to use a paper filter instead of old underwear.
You shouldn't have any problem with the filter clogging after the stir.  I 
have the 36 floz model use 4 heaped or 5 flush blue (2tbls) scoops and grind 
#30 on a Rocky, (what I consider a medium grind).  I let the filter basket 
fill almost full then give it one stir and put the selector on the medium 
setting.  It drains fast enough, I have been using Militia #4's.  Even if 
you have the larger machine, it should not clog with the wide open setting 
if mine doesn't clog with the medium setting.  If it's not the grind or the 
filter, what could make your machine produce hot water too fast?  You don't 
start with warm water do you?  I am out of ideas.
Good Luck,
Ross

Hi John-
Could the valve on the basket be defective--- not opening wide  
enough? I pretty much use Tom's method also on my thermal Technivorm  
without incident. The only time I get any overflow is when I walk  
away and forget to open the valve! I use one of those Melitta (sp?)  
gold-tone filters. Good luck with this. The TV is a great machine.

I would suggest trying it with no filter/no coffee. If that flows freely,
then filter/no coffee.  If that flows freely, then it's the grind.

Thanks for all the suggestions so far. Here are some answers to your questions.
I have tried with no filter or coffee, there is probably no more than 1/4 inch
of water in the bottom of the filter holder at any time.  So it is draining
fast enough.
It brews the 10 cups of water in about 5 1/2 mins which is similar to others. 
So I don't think it is to fast to brew.
Yes I do use cold water.
As for to fine of a grind, I even removed the screw stop in the Mazzer to allow
for a courser grind.  No joy.
I have tried three different #4 filters to include Melitta, no joy.
Here is the method that works, but I don't think I should have to do it this
way.  I start the brew with the valve open.  When enough water is in the
basket, I stir the grinds a couple of revolutions.  After about 2 min. I sink
the floaters into the mix and then wait for the brew to end.  Using this
method, the water, grind level doesn't go above about 1/2 full basket.
Again, thanks for the help.

John,
Sounds like you are working way too hard to make coffee in that T-vorm.  You 
should have a better experience for the price you paid.  One more thought, 
is your coffee fresh out of the roaster?  If so, maybe the bloom is too big 
and a few days of degas will give you the standard results.  Do you fold the 
overlaps (bottom and side) of your paper filter so it fits tightly in the 
basket?   Don't worry about the water and grounds getting too close to the 
top, the grinds alone fill the basket half full so once they bloom you 
expect the mix to be at least 3/4 full, accept the fact that you are 
shooting for about 1/4 to 1/8 inch from the top of the filter,  Try making 
an 8 cup 36fl oz batch using the standard technique, making a smaller batch 
may solve your problem, once you open the filter to the mid click the water 
should not go any higher in the basket unless  1) machine is pumping water 
out too fast, 2) you have some sort of obstruction in the bottom of your 
filter basket or 3) your coffee is too fresh or ground too fine.  It sounds 
like you have eliminated all the possibilities except just letting the brew 
come up close to the top without worrying.  I trust that your Mazzer can 
make a medium grind.  And for now I will trust that you have a normal T-vorm 
boiler.
Lets look again for a problem in the filter basket drain.
Time the flow of water from your filter basket no filter, from overflow 
cutout to bottom:
Medium position: 1:06
Full open: 0:36
If your results are similar, it's time to check the T-vorm.  Time 36fl oz 
out of the Technivorm, and someone can bench mark that for you or I will 
tomorrow when I make my first pot.  If you really need to make the 10 cup 
full pot you may have to use the full open setting on the filter basket.
If the problem is with the filter basket, you might have a plastic burr or 
something obstructing the opening, get a drill bit that fits tight and twist 
it with your hand to ream the hole in the bottom of the filter to remove any 
burrs.
Wishing you a painless coffee brewing experience.
Good Luck,
Ross

Thanks for the help.
Here is some of my findings.
Water flow thru empty filter basket... Medium position--1:20
                                       Full Open-- :40
Time for 10 cup brew, from time switch is turned on until T-vorm turns off- 5:43
You may have something with the bloom. But by the time the brew is over, the
bloom has mostly disapeared.
Yes I do fold the edges of the filter.
Do I really need 10 cups...
Had to laugh here...  No, I do two brews for 20 cups...(:-)
I fill my thermos and take the other 14 cups to work.  Which is usually gone by
10 am...
I suppose I could break it down to 8 cups or so, but I would have to start
brewing a 3:00 am instead of 5:00 am....(:-)
I may have to get in touch with Tom and ask if he can tell me if my Mazzer is
putting out to much dust.  Maybe mine has malajusted burrs or something.
Again, Ross thank you for your help and suggestions.

John,
Well it's slow, get a drill bit and ream that baby out.  Then at least you 
can relax and enjoy your coffee while you make the second batch.
