Fancy a 'perfect espresso'… https://www.theguardian.com/food/2023/dec/06/scientists-claim-to-have-discovered-secret-to-perfect-espresso

Every time I read a Guardian article it reminds me why I don’t read The Guardian.

Anything that quotes 'scientists' is clickbait.

RDT is at least 18years old to my knowledge. CH Hendon didn't discover it.

"Now we know what grind settings to use to make reproducible espresso, we can start to try to understand what factors give rise to sensory differences in coffee taste.” ![Giphy - Season 4 Wow GIF by The Office](https://media1.giphy.com/media/b8RfbQFaOs1rO10ren/giphy.gif?cid=bb77869fjpqxrds1embymrlnuwtdexkqawnp1rw4eyeilyl0&ep=v1_gifs_search&rid=giphy.gif&ct=g)

So, according to Joshua Méndez Harper, an assistant professor of electrical and computer engineering at Portland State University, grinding coffee has a lot in common in pyroclastic flow.

If you're a volcanologist, everything has something in common with pyroclastic flow.

The paper agues that RDT results in a smaller peak grind distribution, longer extractions and higher extraction yields. The article effectively says the same in more general terms. I'd not seen any of the other claims made in this paper used as justification for RDT before, aside from causing less static mess.

RDT = Ross Droplet Technique Come from an old post on alt.coffee in 2005 from somebody called David Ross. Ah I see I'm late.

MWJB Will do. For now, I think I’m going to take a break. I had so much coffee while testing that I couldn’t sleep!
