That's when you chew the beans. I don't know how humanity invented something that requires so much effort for so little result.

I do appreciate a fresh ground cup of jo, but when you accept a 2nd cup from your friend and then watch 3 minutes of grinding you start to feel bad.
grinding 23 g of beans (standard 1 serving) on medium for a fresh pour over takes <1 minute. I know because I've timed it and I do it every day.

I'll be honest though, lately I've been creatively lazy and attach my power drill to the top and let it do the cranking. I got this idea from a high end coffee shop that I saw do the same.

Ceramic burrs. Bestseller list has a bunch of these no name $20 or less manual grinders with similar features. Do any of these actually perform decently?
I have a cheap hand crank ceramic burr grinder from Amazon. Been using it for a year. Works great. <$20

I have a similar one which costed $17. Very reliable, doesn't break and you just have to spend 5 minutes of your life to grind the beans down. A time to grind, turn, turn, turn .....
I've started attaching my power drill to the top and let the electricity crank for me. I actually got this arguably-ridiculous idea from a high end coffee shop.

I use a similar one for pepper grinding. Get something with stainless steel burrs for coffee.

I hear the Hoff loves this for his espresso grinds! Not for pour over or drip though, too fine. /s
Thanks for this. I want a grinder but use pour over makers and was considering this. I'd like to get a manual grinder that does coarse grinds well.

The low reviews mention it working well at first but rapidly deteriorating and not grinding well. I guess for $10 bucks you could do a lot of grinding during the return period and see how it holds up.

I did that about 12 years back for a couple years before I purchase a decent electric grinder. It works very well!

Our community has rated this post as helpful. If you agree, why not thank

A hand grinder is probably something I never would have bought (I got one through Amazon Vine) but for all those who think it's ridiculous consider this:
1. It's cheap, and it affords you exacting control over how fine you want your grind.
2. It's quiet. When I'm the first person up in the morning and I want a fresh ground double espresso, plugging in the electric grinder is a good way to piss off the rest of the house.
3. It doesn't take long to grind one cup worth. I turn on my espresso maker, pour the beans, grind it, and by the time I'm done grinding the machine is ready and the portafilter with yesterday's grinds is loose enough to flick it into the garbage (rather than banging it - another early morning crowd pleaser).

Does this replace your electric grinder? No. Does it still have a place in some kitchens? Absolutely.

Yeah, if you do pour overs, it's better to spend a little more on a stainless steel burr that reliably produces less fines

Good electric conical grinders are pricey. A manual grinder produces great results for usually less. I just wanted a good grind and none of the noise, so it works for me. Going to try it with my power drill though.

Hey never know. It could be a diamond in the rough. I could only find unboxing and AI generated videos that "reviewed" this thing though.
Not ready to risk $9.89?
