My grinders don’t really produce static so maybe I don’t get the appeal, but putting water in your grinder just seems like *such* a bad idea for both sanitary reasons and longevity of your burrs/grinder

It’s way too much for most grinders but the study says you need 6-7 pumps at least from those small sprays to make a change in how grind size is affected. I only do a couple as I just want to minimise static.
Doing it right you will have to adjust your grind so much it will surprise you.

It’s the wrong kind of soup.

i stopped rdt when i cleaned my burrs the first time.

Probably just going to gum up the grinder but I’d imagine someone as obsessive as this person would be is cleaning the burrs. Can’t imagine it would affect the taste or anything negatively, it’s about to have a lot more water added to the equation.

No. The heat generated by grinding the beans more than evaporates the water off. You could even get away with more water than this

I dont get why people dont use an electric atomizer. Can get it for t bucks and its so much better

Isn’t this guy also adding random things like candy to his basket for click bait? The water is the least of his problems.

One of these tutorials fucked up my df54 grinder because it turned everything into a coffee bean paste. I had to make my husband spend 1 hour taking it apart at 8 in the morning to clean it. I am honestly just happy to keep the static although I am hating the grinder at this point

Honestly if I don’t put that much water, I get so much static in my DF54, it’s terrible. Never had ANY issues with the grinder with putting that much water. I also shake the cup aggressively after spraying to try and make sure it spreads across the beans though.
shhhhh_lol
The ole’ “budget” setup

Nah I soak mine overnight and use that water to pull a double shot in the morning. Sure yea the grinder gets a little gunky, but it’s like a cast iron skillet, just seasons it. You should try it! /s

I’ve wondered if steam from the stream wand might be useful here. Never googled though…

I just switched to a new bean that’s created a lot of static. Half a spray of mist is enough to rid the static

1 spray per bean

Not saying this is the right way but i usually spray the palm of my hand and then shake the beans for about 10-15secs.
Not doing this loses yield by .2-.4grams at the other end.

I’ve never sprayed my beans in the past 8 years (7000+ espressos)

I just put the beans in my mouth and spit them directly into my grinder, works like a charm.

Is this the soup method people talk about?

No, that’s way too little water for espresso. I like my espresso at least 40ml and the beans grinded.
On a serious notion though, who the heck spray the beans with water before grinding them, when their grounds are being soaked with water afterwards? How that drastically change the taste?

It’s hard to actually make it too wet… Imagine how much powder grinds through there. It takes all the water.

If I understand correctly, you need a lot more water to make coffee

I’ve washed coffee before, it’s so hydrophobic it doesn’t know it’s been wet. I tried it 2 times with 1 day old coffee, the idea was to speed up the degassing. The cup was so wonderful. And the rinse water tasted like a hessian sack. I’m pretty sure that dusty flavour is on all coffees and might want to be rinsed away. The grinder was ok with the wet coffee.

How much really is too much? Does it course droplets from an old hairspray bottle make any noticeable difference than a $90 battery-operated atomizer?
Unless this causes the grinder to rust, I can’t imagine it matters all the much.
Yes. It may eliminate static, but it will cause sludge, resulting in a net negative impact.
I saw the video and thought the same thing, but I generally don’t recommend RDT. At best, it’s not hurting, and at worst, you get this

Them boys swimmin
Few more pumps and the coffee grinder can be converted into a vitamix smoothie blender.
This went into a weber EG-1 🤦♂️
Talk about a pre-infusion
This is why y’all’s burrs are nasty when you open your grinders.
Per the Hoff, no. https://youtu.be/nLnB99VJ0HE
