Topic: Krups Moka Brewer (17 msgs / 306 lines)
1) From: Brian Kamnetz
I've never made a full pot with the Krups Moka Brewer. How many grams of
coffee should I use, and how should I grind it?

2) From: conradarms
I use 1/3 cup of unground beans for 3 cups of water  (3 cups per the caraf)

3) From: Eddie Dove
Brian ... anywhere from 45 to 60 grams depending on your taste.  I prefer 60
grams.  Vicki sent me her document for using the KMB.  I can forward it to

I'll just go with the 60 grams. I use about 20 grams for about 14 oz of
water in the Moka Brewer, but as many folks have mentioned, the KMB doesn't
do as well with small batches as it does with full pots.
I decided that I will bring in my KMB and make a pot of coffee here. Some on
the list may recall that I brought in beans and ground them here and brewed
in the office Mr. Coffee, and it turned out thin and bitter (though the
people here really liked it). So I decided I might as well just bring in the
Big Gun!

Just be clear that no one else is allowed to touch it!  If after you have
experienced the nectar yielded by the elusive apparatus, someone else were
to break it, violence may ensue.  I would plead insanity ...

Good point, Eddie. Now that they are no longer freely available, that is
even more important. When I saw Ann's note the other day that the basket
unraveled on her KMB, I decided that, even though I have one KMB that I use
and two in reserve, I'd better check out the Tuesday Mornings and see
whether I can snag another reserve....

I might know where you might get one slightly used.
When I bought mine, a few months ago, I liked the flavour of the first 
few pots.
Since then, I get this metallic, acidic flavour hitting my tongue first, 
and it has spoiled it for me.
I thought at first I might be experiencing a temporary change in my 
sense of taste, but I still love what I get from my Aeropress using the 
same beans.
I don't understand it at all - why has no one else complained of this?

I just purchased my KMB a few days ago and so far love it.  But your mention of metallic acidic flavour is of concern to me.  I'm wondering if you have limescale buildup?  If you did have it and cleaned it, what did you use to clean it?  
Thanks, your answers will help me in the future............Dorothy

I had wondered about water quality when I read Dave's post. Even though 
the water reservoir is stainless steel, and should be non-reactive, 
something is going on that is specific to either that particular KMB 
(which, I suppose could be defective)or to the water or technique used 
to make the coffee.
I know that before I started using Brita filtered water, I would get 
quite a bit of scale in the reservoir. I didn't notice what I would call 
a metallic taste, but the coffee quality suffered if I didn't keep the 
pot really, really clean--and not just the reservoir, but the lime 
buildup in the glass carafe as well.
I know the carafe, even with filtered water, really benefits from a 
frequent application of vinegar or something like CLR. I'm always at how 
much clearer the pot is after I do my daily vinegar scrub.
I don't know if the fact that the KMB steam brews increases the lime 
build-up issue, but I do know that it seems really, really important to 
keep the pot sparkling clean.

Thanks for your comments, Dorothy and Vicki.
As to cleanliness, looking through the carafe I see no brown tinge, 
making me think it is clean. The boiler part is shiny-clean looking. I 
haven't done anything about cleaning except normal wiping and rinsing.
After your comment, I took a second look at the lid, and sure enough saw 
a layer of brown around the edge of the metal diffuser. I had never 
dissembled the lid before, but after removing the little screw, and 
finding no stale coffee material under the diffuser, I was satisfied 
just to wipe the diffuser and the rubber gasket. I'm doubtful that that 
would have caused the strength of the off-taste I've been getting.
On water quality, I use water that has been through a Brita filter. We 
don't mind the taste of the water that has been filtered that way and 
kept in the fridge.
This morning I decided extreme measures were in order before I sell this 
thing. I ground my coffee as course as the Capresso Infinity can make 
it. The metallic edge is still there. My wife tasted mine (hers had milk 
in it and didn't seem to have that problem) and detected it as well.

If I were you, I would get a citric or tataric acid lime scale remover, as recommended by Krups.  I would try the lime scale remover before I dismissed the KMB.  I'm sure you can get them at your local supermarket.  Anyway, whatever you do, let us know.

The problem may be in the channels through which the steam travels north.
You may wish to clean it as suggested and see if it makes a difference.

Definitely watch what scale remover you use.  The 'diffuser' is made of
aluminum.  It's the only part made of aluminum I believe.

I think the tube that carries the steam to the top is also aluminum.
So which scale remover is safe to use with aluminum?
(Not that I really believe this is the answer - I've made less than a 
dozen pots of coffee with this machine!)

With a dozen pots of coffee, I don't think it is the scale or build up 
either. I do though wonder if, even after using the brita, there is 
something in your water that is reacting to the pot. It also might be 
that the pot is defective in some way. Clearly, it is not a common problem.
Just for giggles, go to the store and buy a bottle of good water--like 
crystal geyser, and see if it makes a difference.
It's worth a shot.

Oh, wow, I wouldn't think 12 pots would cause much build up either.  But
it could definitely be the water.  I know I noticed a big change after
we put in our water softener and whole house filter.  Our water here is
very hard.  
Anything listed in the manual should be safe for the aluminum.  I used a
sodium carbonate based cleaner in mine and I could tell it had an effect
on the aluminum diffuser, changing it's color slightly.
