Hi all. I'm new to this site and looking forward to all the information and advice available! What a great place.

I have a potentially very silly question. At work yesterday (I work at a very hip indie coffee shop, they're "purists") my boss and then later a coworker mentioned "dilating" the espresso  grinder. I was embarrassed to admit that I didn't know what they were talking about so I never asked them to clarify. This is the third coffee shop I've worked at and I've never heard of that... I even looked it up on google later and found NOTHING.

Can someone explain what dilating the espresso grinder means? Is it just dosing and running one shot as a test before you start pulling shots to serve? Is there some kind of actual mechanical function?

I'm going to feel really stupid if there was something I should have been doing and I haven't done it for the three weeks I've been working there! No one training me ever mentioned anything about it.

 

Thanks for any help!

Your first mistake is not asking your boss a question when you don't know. NEVER think you do or should know it all. That is stupid, not knowing is not stupid.

 

Never heard the term dilating used in grinder terms. But since dilating is enlarging or expanding seems to imply opening the grind, making the grind coarser.

You're right about not asking them. I just heard it mentioned in passing, not to me specifically and not as an instruction, so at the time I didn't think to ask. Just wanted to see if anyone on here had heard of that before I go into work the next time and have a chance to ask them.
Pretty sure they were talking about dialing in a grinder, which means changing the grind settings either courser or finer, to produce tastyer results.

I've had my eyes dilated at the eye doctor, but never heard it used in reference to a grinder. Probably an inside joke, referring to grind adjustment.  Along the same lines of my last trip to Canadia :).

 

Not official terminology, as far as I know.

Haha, okay great. It makes sense that it was some kind of lingo referring to "dialing in" or maybe I even misheard them!! Anyway, I know how to adjust the grinder, so that is a relief. :) Thanks for the input, all!
