Posted Wed May 30, 2012, 1:27pm Subject: Dialing in (Mazzer Mini-E) (First Post)
Hello,
I am starting work tomorrow in a small coffee shop in my local area. I have a fair idea on dialing, thanks to the courses I undertook at 3FE. I had a quick question regarding the dialing in procedure on the Mazzer. I hear the dosing timer is inconsistent so for dialing in, would I be better of adjusting the grind manually, rather than using the dose timer at the bottom of the grinder.
i.e. I'm aiming for 18 grams for a double shot. Double shot is coming out at 16grams, adjust the grinder to make the grind more course. Time the extraction, weigh the yield, and adjust the grind accordingly. Or would it be easier adjusting the dose with the timer, to get the weight I want i.e. 18grams, reviewing the shot and adjusting the grind size accordingly.

The dose and the grind are 2 completely separate things and they both need to be adjusted at the same time.
At first you will have a bit of a guessing game as to how much to adjust the grind and how much time to adjust but you will quickly learn to get closer and closer.
good luck and congratulations on the new job. you will have it figured out in no time.

I think it would be easier to get dialed in by first getting the desired weight by increasing the grind time on the timer, THEN adjusting the grind a little more coarse to compensate for the higher dose. Assuming you are happy with the flow rate and yield of liquid espresso coming through the espresso machine using 16 grams of coffee, that flow rate should be your constant (i.e. you want to adjust weight and grind to maintain that same flow rate).
I had a regular Mini (not the Mini-E), but being familiar with the Mazzer collar adjustment mechanism, if you are upping the dose by 2 grams, you will want to move the collar mechanism only about 2-3 notches (NOT whole numbers, but the little notches between 2 numbers). I have found with my Mini that a very small movement of the collar can make a big difference on your espresso flow rate.
