In the limit, you can get coffee routines like this: [0]

"...our very expensive grinder." To save you the effort: that's about $4300 of coffee grinder, in that video. (Weber EG-1, Black. White is $400 "cheaper.")

That routine is robberr baron extravagant.

Been doing it for a year or so. I grind for espresso and can see a clear difference in how clumpy my grinds are and how much is left retained in the grinder.

Lance Hendrick has a nice deep dive on this paper as well https://www.youtube.com/watch?v=GuqVUsMPs-U&

Yes, this has been known for quite some time by coffee experts (and is presumably why it was tested in the first place, to see if the dogma held true).

Why would static charge affect the final flavor?

In the event that static caused some ground beans to stick to the wall of the grinder (or brewing vessel), continued use of the grinder or brewer would quickly reach a steady state where the throughput is ultimately the same, because the "binding sites" of the grinder or vessel are essentially saturated.

Can an expert help me understand this better?

Finer, more chaffy particles stick to the wall more, affecting grind size distribution and with it extraction profiles.

Assuming that retained grounds in the grinder operate like a FIFO it's just that they go stale quickly so ruin each next day's coffee. That's what Hoffman implies anyway.

Until my Nespresso can do this, there's no point :)

However as a Nespresso owner I'm already taking a lot of waste for granted obviously.

I guess you could do it too if you had a reusable pod…

But Nespresso feels like it caters to “I want it now”…

Do people still drink coffee? I thought that was a Boomer thing that lasted a few more years in Seattle but pretty much over and done.

I thought people realized that harvesting coffee was mainly through forced child labor

Is this sarcasm or are you that out of touch with the entire world? I need to know so I can decide whether to vote your comment down or up (in that order) please.

For real….
