Subject: The Compak K3 Grinder User's Thread
 

Hi,
I'm new to "real" espresso. My first serious gear is on the way (Alexia/Compak K3) and would like some help with the initial setup of the grinder.

I know that the K3 has a very broad (aka little usefull) scale markings but it would be helpful if you could help me to get started with an initial startup position and how big (mm-wise) adjustments should I make to dial it in.

Something like this would help a lot: "Start at the midpoint between dot 4 and 5 and work your way counterclockwise by 2 mm at a time" for example, but any pointers suggestions will be appreciated.

Thank you

It will come from the factory calibrated to the espresso range, so the "start between dot 4 and 5" part should be taken care of.

Unfortunately, the fine adjustments it will require are based on too many variables for anyone to presume what actions you will need to take.
Without further information it's not even possible to tell you which direction to turn the adjustment collar.
I can tell you this:
clockwise -> course
counter-clockwise -> fine

That's a nice set-up you've got comming, enjoy!

 
enjoy the journey

Here is a photo of my Compak K3 touch in the espresso range which will obviously vary a bit from day to day and with different coffees.  

Also, notice my homemade calibration scale whcih is very easy to make and it works a heck of alot better then the sad scale on what is otherwise a really good grinder.

a Home made scale seems helpful indeed.

Follow-up question:
what would you say is the minimum amount of adjustment that you would notice a change in taste? 1mm? 2mm? etc
In other words what is the minimum resulution of the grind adjustment?

Again, thanks for your help.

Each mark on my scale is made at 2 mm intervals.

If I change from a regular to a decafe for the wife's cappuccinos it may go from 22-23 all the way up to a finer grind at 25-26.  Usually I don't need to move more then 2-3 mm to fine tune a volume or time for a shot. As reference to where I am you can see the centerline of the grinder at about 11 on my scale.

I can't answer the question about french press and the COmpak K3 as I have never attempted to grind for anything but espresso.

I have a Virtuoso grinder that I use for french press and it works fantastically well for that purpose.

Sorry

Compak has shown great ability in the past to answering professional wants and demands for modifications and changes on their pro line of grinders, putting the K10 and K6 through evolutionary changes to meet those demands (often, the pros equate them and Mazzer as a day and night difference in terms of cooperative discussions).

We're getting three Compak grinders for Detailed Review for the new CG site - and it seems that this complaint about the K3 is common, so I'll be sure to bring it up with them.

Best case scenario - they put a new collar on with better detailed markings, and make it retrofittable and available for sale for existing K3s.

That would be a great service to the Compak customer base if you could do that. My scale (otherwise known as ultra low temperature freezer laboratory tape) will be in need of replacement from general wear and tear in the future.  A permanent fix would be nice if only for the aesthetics.

Thanks

Geoffrey
