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!
