Spoiler, its RDT
In case people do nto know what RDT is, which they really should if they have been into coffee for a little while as it makes a big difference:
RDT is Ross Droplet Technique, which is very much adding water to beans. Named after David Ross who came up with it back in 2005
True but I would believe the general level of enthusiasm for a conversation about RDT would be substantially higher in a modern espresso group vs filter coffee folk.
Also my previous comment is bit of a inner monologue as someone who posted very randomly detailed things on r/espresso back in the day and rather uncertain if/where I would post that stuff on Lemmy.
