A Grinder PSA.I know James Hoffmann, in a few videos now, heavily suggests doing the RDT (ross droplet technique) on coffee in single dose grinders; indeed, in one video, he heavily suggests doing this 3x as much to get, as he says 'better anti static ...

@coffeegeek @coffee @espresso is this method useful for hand grinders?
-
@coffeegeek wait, coffee grinders have plasma generators in them? I know little about coffee but am a plasma physicist, so am curious…

@coffeegeek @coffee @espresso
As the owner of a cheap plastic-binned coffee grinder, I simply walk away for 15-20 minutes, and the static charge dissipates on its own. -

@coffeegeek Sorry for my ignorance. What is a plasma coil? Search results were polluted with references to a type of gun in a video game. Is it related to an ionizer?
-
@tedmaul you are correct; I blame my late night typing for the faux pas. He did the video to show it can give higher extractions, as per that science study that came out independently.
-
It can, but often, a good knock on the counter can dislodge the static build up stray grounds with manual grinders. I don't RDT manual grinders myself.
-
@ezwal yes they do - coils that fire away during the active grinding. the Turin DF64 Gen 2 is one type.
You can also buy kits to add the functionality to existing grinders

@ccunning yes, both terms are used interchangeably in grinder tech.

@coffeegeek Good to know. I do have periodic issues with my Fellow Ode 2’s ionizer not working, but I’ve never used the RDT with it before ¯\_(ツ)_/¯
Lightly brushing out the chute has resolved it thus far, but I have wondered if it’s something I should be concerned about. Especially while it’s still under warranty…

@ccunning Do you use particularly dark roast coffees? The oils from those can also gum up the ionizers / plasma coils. Brushing will resolve.

IMO, that's too long to let grinds sit. They are going stale, losing all their Co2 in that time.
Oh dear... Whatever you must think of me grinding my day's worth of coffee (36g) in the morning and then using the second half in the afternoon!
Also I don't own a plasma generator... I wet my dirty fingers and twirl them in my beans LOL

Aaaanddd that's when this becomes an obsession rather than a beverage. -

As my Dad used to say "whatever floats your boat".
But science is still science, even if you don't like the results it provides. Roasted coffee, when ground for espresso, loses up to 80% of its stored CO2 in the first two minutes. It takes about 5 minutes for pour over grind. C02 is an important flavour transporter to your cup for non-soluble fats, oils, lipids.
