Jeez, dude... That's EXACTLY what happens. It's called a "bloom". Here, first hit in Google - https://www.roastycoffee.com/coffee-bloom/ https://www.roastycoffee.com/coffee-bloom/
>Really? Any uniformity in grind will block machine? Could you explain physics behind such phenomenon please?
Yes, really. Give it a try. Better yet, read a book on a subject. Something like Blue Bottle's intro into coffee making.
- pandaman 7y agoI wouldn't trust coffee makers as your source of physics and chemistry data. Instant coffee "blooms" too, it's not espresso foam and it's not caused by "captured CO2". Highly uniform ballbearings do not restrict flow any more than other particles of comparable sizes. And, not mentioned by you yet, but my favorite coffee people "fact" - distilled water does not cause more corrosion than tap water.
