Hi,

I’m not happy with the strength of my expressos in my Jura Impressa E75. I use every option there is in my machine to get it better but with no success. I use the finest grinding, expresso extra (when brewing) and the extra aroma-option.
I suspect the grinding to be the fault.
I’ve done a little test to examine the grinding. I’ve put a white paper into the trester and brewed a cup of expresso. I put a new white paper in the trester and used ordinary brewing coffee which I inserted into the hatch. Then I examined and compared the coffee-rests. I also waited for the remains to dry to make an even better examination. From my point of view the grinding of my beans isn’t any finer than ordinary brewing coffee-powder (no espresso coffee). When I manually brewed espresso in the old days, in my non-automatic brewer,the espresso-coffee was a much finer grinding than ordinary coffee. How is the grinding expected to be in the Impressa? ???
There is a problem that I don’t know what I should compare against..  :'(  and no other automatic coffee-machine to have a test espresso from….

I’m thinking of getting my espresso-beans professionally grinded in the coffee-shop and try those in the hatch to se the result and taste. Is this a good step to try out?
Should the grinding be that fine in the Impressa as it is done normally for espresso-coffee that are used in a manually handled equipment?  ???

I’ve read some other inlays about the grinding and you gave someone a tip of turning the black ring on top of the grinderunit to the left. Could I try this out to?
I’m anyway into that I maybe needs to change the grindingstones. If so I’m into changing the whole unit (not only the stones) to be sure to get the optimal grinding. I’ve read some inlays with people having problems with there new grindingstones. If I buy a new unit I would be sure to get the grinding-unit perfectly syncronized. Is this correct thinking?  ::)

Would be happy if you guys could light up my dilemma a bit. 

I’m also throwing in an extra bonus question  ;D
I’m wondering how it is supposed to clean the PAC after every use? The PAC i s working very well but is very sensitive against rests. Right now I de-mount my PAC every day and puts it in a high glass of hot water over night. Is this OK or could I damage anything in the PAC when it is luying in the water for many hours often?

Regards from a snowing Sweden

Because you are saying that your coffee powder looks like ordinary coffee powder, I am sure that everything is ok with the installation of your grinding stones. Keep in mind that the degree of ginding is coarse to avoid that the filter in the brewing unit gets clogged.

If you like to experiment a little bit (I know you like to ::) ) you could try to adjust the grinding unit to produce a finer coffee powder. As you have mentioned, move the ring one or two notches counter clockwise. But be careful, you should avoid that the grinding stones touch eachother. Produce one better two cups of coffee and then take a look at your „Trester“. It should ne now much finer. If the coffee dripping into your cup, then you have choosen a to fine grinding level…

I am interested in hearing your results,

Ralf.

Off Topic…..is it true that in sweden the radio stations broadcast in 6.1 Multichannel DTS-Sound?

Right now I’m hearing a soundtrack of sweden radio where they make some advertising for the new swedish brodcasting system for DTS an Dolby Digital.

Nico:   I don’t think swedish radio broadcast in the multichannel-mode but I know there are a lot of concerts etc. to download in different multichannel-modes.
          But I’m not an expert in this. Maybe you know more….   :-\
         
I’ve tried some adjustings to my grinder.
But I have one big question first:
Is it the black ring on my picture that I should rotate (of course I would remove the little adjuster first)?
The little adjuster makes the black ring to go clockwise when adjusting to the finest grinding. To follow your advise, and get a finer grinding, should I then adjust the outer black ring clockwise a few clicks?
If I do so you could see on the picture that there would be no „tags“ on the outer black ring to fit the small level-of-grinding-adjustor. But I could live with the no possibility to adjust as long as I get decent coffee. My espressos are thin and you could easily taste the water so there has to be something that has to be adjusted.
Am I on the right track?

Hi Christer,

[quote]Is it the black ring on my picture that I should rotate (of course I would remove the little adjuster first)?[/quote]

Yes. Remove the adjuster first. You must lift up the black ring. For that you should remove the three screws to be able to take the grinding unit a little bit out of the the machine. You don’t have to remove the cabeling that is connected to the grinding unit, just take the unit a little bit out of the machine.
Don’t forget to mark the position of the black ring in reference to the rest of the grinding unit!
Take a look ad the side of the black ring. The black ring is linked with the the rest of the grinding unit with two or three connections. Just lift the black ring over that holders.
Now you can see a white ring with a lot of holes in it.
Turn the black ring counter clockwise, but not more than one or two holes. Put it back on the grinding unit, fix it. Install the unit an test it.

Ralf.

Hi Ralf,

Now I’m on the right track….. I think ::)

I’ve adjusted my grinder 5 klicks 😮
Now it is a much better coffee. I’m going to try and adjust it another click more to se if there is still room for more improvements…. ::)
My grinder must have been taken apart before I bought it and not properly put together or? 5 clicks must be more than it should be :-\
But now I have the problem with the „Fill beans“-error message after every cup I draw but on the other hand the coffee taste more like it should.

A lot of people are struggeling with the color marks on the grinding unit. That markers are only valid for the grinding stones currently installed in the grinding unit. Once you replace the stones, that markers are now longer valid! Every grinding stone set hat it’s own perfect position. Could be 18 clicks, but it could also be 22 clicks!

Regards,
Ralf.
