Hey everyone, here’s a statement from CafeSing regarding the similarities of the Potu grinder others have pointed out: “Hi guys, we want to clarify two points: 1. The flat burr hand grinder was a collaborative development between us and POTU. 2. POTU will transition to electric grinders and no longer offer flat burr hand grinders.”

Just want to note how good your production values are. Makes concentrating on the information easier when the music is subtle, the pacing calm and the editing smooth. Thank you.

This is definitely an interesting product. If I were someone who used a hand grinder for all my grinding (pour-over & espresso), I could see this being worth it, easily. I’m always amazed how much progression we’ve seen in the coffee world in the past 6 or 7 years, and I’m glad this channel has been around to keep me up to date on so much of it.

The ghost burr option makes this very enticing and i feel like that price isn’t bad at all considering that the pietro is way more.

Great video man!!! Like you I don’t use a hand grinder very often but the Orca has been my favorite!

This is such a cool hand grinder. Ty for making this video Spro

Hand grinders are great.....when travelling 😉 Finally bought a super compact Timemore Nano, and I am happy with it. But at home I love electric ⚡

seems cool, I like it comes with the pair of flats by default too. nice!

The grinder reminded me of a Grindmaster I used at a previous job for cupping. It had similar burrs for the filter, had a cool even grind!

I had a Premula hand grinder. I liked it pretty well . This that you have here is well engineered and Im going to go out on lim and say its probable that the Cafesingh is the best coffee grinder in the world to date. Thats just my gut reaction. I hope I can buy one. I think It would make me very happy.Thanks for excellant review.!😅

Thanks for your review. Very informative for us that hand grind. I have learned the importance of particle size and consistency through your videos but couldnt afford a quality electric grinder so these are the next best. 1Zpresso was new when I was looking so I got one of their mid priced ones and have been happy with it. It has a quality machined body with conical burrs that has exterior adjustments. Use it for both espresso and moka pot

Have yourself a great weekend. Thank you my friend.

Thank you so much for the review. This has been a very interesting product indeed. In your experience, how many clicks are usable for espresso? Are there enough clicks for dialing in?

Looks great and thanks for expanding your hand grinding content! I am obsessed with manual grinders and brewers. The external dial is absolutely delightful but nearly ruined by the fine threads on the catch cup. Arguably it is the piece you will be interacting with nearly the most and having to thread and unthread them constantly is annoying. Chunky quarter turn threads, magnets, or other novel joining methods are very popular and achieve better results. To be lacking these types of premium features is softened by the unique burr sets it comes with, but I would like to see a generation or two ahead of this design.

Those those that hand grind, a tip is to sit in a chair and hold the grinder between your knees. It makes grinding dramatically easier. I keep thinking about building a clamp on my kitchen counter, but I think my wife would veto it :-) It would be interesting to see if the flat burr would work as well using my method (since the grinder is totally vertical).

Hi Spro, great video. I'm considering aDF64v, and trying SSP burrs, maybe Cast Sweets. What IS sweetness in the cup, i finally want to taste. But these ghost burrs might have sweetness too. What do you suggest? One reviewer seemed to have the Sing' handle slip off a bit while grinding. Can the ghost burrs do well for v60? how slow is it to grind 30 gms at v60 ground size? (for a Clever). Thank you kindly Spro. You painstakingly create such calming videos about caffeinated beverages!

Love me some good perfromance 😉 So as not to be that guy who only comments on a spelling error: I've been watching your videos for years, you are one of the few coffee creators that it does not matter what you cover, I'm here for it. Thank you!

Thank you.

I got a cheaper possibly cousin of this grinder that's just a ghost burr (non branded but I've also seen one that's identical but with POTU on it). I find it gives me a lot of fines, they don't seem to affect the taste though besides potentially clogging up the pour-over filters and extending the brew time. One characteristic of it I noticed is that it lacks acidity or brightness, it's different and can be nice, but I'm finding its kinda hollow feels like it's missing something without any brightness or acidity. Interesting your ghost burr grinder doesn't give the same effect. I also got a Timemore C2 and 1zPresso Zp6 which I like a lot more, both nicer to use too.

Does it have in between steps? When is the bottom “fine / rough” adjuster used? At changing burrs and calibrating them, I suppose.

Great video! I see a df64 gen 2 in the background, are you making a review?

Like the concept for sure, but it may not be the most consistent from unit to unit. It doesn't have great reviews on Amazon regarding the build quality. And on the other end of the spectrum there are folks that love it and have rated it pretty highly. I would be curious to see what they can achieve on a future V2 model.

Hi... between the bimodal and ghost burrs, which had more resistsnce in grinding for say the same grindsize?

I have the Kinu M47 and Pietro and happy w both.

How does this grinder do for light roast? I have a a JMAX which is excellent- except for light roasts- can barely turn the handle. Thanks.

Anyone know if this would be good for grinding light roast espresso which needs to be quite fine?

Now I need this vs the ZP6… hopefully you or Lancey pants will do that video soon.

does it uses the same hex nut like the one used for most other hand grinder? My trick with my 1zpresso is to connect it to a wireless drill to make the process of grinding easier.

Are the burrs always making a touching sound for you? I recently did a burr alignment test and got partial dry erase marker wipes even at the coarsest setting. Is that how it should be or should I be contacting CafeSing?

Did you find the grind setting shifting during grinding at all? The adjustment ring seems to slip with the lightest, inadvertent contact.

Just got mine. I love the ghost tooth burrs. It has its quirks but is about as close to a happy medium of exceptional grind quality, good workflow, and price as I've seen on the market so far. I get why people love the ZP6, but it doesn't work as well for some of the brewers I use (SOFI 72 among them).

How long did it take you to grind through an espresso dose on the bimodal, and a filter dose for the orea on the ghosts? Appreciate this varies based on beans

How does the Orca compare to the 1ZPresso J- MAX?

Does the ghost burr have the capability of grinding espresso-fine?

Very interesting, although I'm still wondering who really uses a handgrinder to make espresso. I use a 1zpresso kmax daily for pourovers, which has a particulary long crank handle and grinding for espresso is a pretty physical process, even by prebreaking the breans beforehand.

Interesting, BUT... I use a J-Max for espresso and it's 8.8um clicks are just great for espresso: I sometimes adjust by a single click, but I don't feel the need for stepless and I chop and change coffees from one grind to the next. But due to the conical burr angle, and simplistic vertical adjustment spec, the J-max actually adjusts it's burr gap in incredible 2.5um increments! I really struggle to believe that 18um actual burr gap adjustments (as flat burr translates vertical adjustment directly into gap adjustment) would be anywhere near fine enough to live with for espresso. 1Zpresso undersell themselves badly, with Commandante, Mazzer, Knock all taking burr taper angle into account when specifying their adjustments. The ultra affordable KINGrinder K4 slaughters all those with it's 4.6um burr gap adjustment (half that of an Aergrind and a quarter of that of a C40 with RedClix), but the 1Zpresso J-Max is presently the stepped fine adjustment espresso focussed champion of the hand grinder world at 2.5um closure per click!

Have you tried the Brazilian made Bravita hand grinder?

Thanks for the review. I have had a had grinder with a bottom that needs to be screwed on and unscrewed. The 1zpresso I have now has magnets. Much more enjoyable. At 8:45 of your video you have an espresso cup I like! Where might I find those? Thanks again.

one of the best hand grinders should have to play 😂

Interesting that aramse had a very different take on it

I wonder how it would fair compared to the 1zpresso KMax!

About how long does it take to swap the burrs? If it’s more than a minute or two, I’d say it’s more gimmick than anything. Especially if it’s somewhat frustrating to zero after a swap.

Can this be used with a cordless drill (like 1zpresso)?

Can't imagine it's better than my Pietro with brew burrs.

Perfromance

How much do these burs cost to make? I can't understand why such a thing should cost 300 usd. Or 250. Or 200. Or 150.

USALIBITU AND PREFROMNACE

Bought into the hype of ghost teeth profile so picked up an Orca. Ran plenty of excellent coffee through the thing. I tend toward the more developed end of American light, so lots of Sweet Bloom, Little Waves, Mother Tongue, Heart etc. Across the entire spectrum of brew methods, it never did anything better than a regular old K series burr, and the UX left plenty to be desired as well. Do not recommend.

☕☕☕ Love Is Important 💘❤ .... .

18 micron per click is too big. I have a 1zpresso that does 8.8 micron and still wish I could have half a step.

For easier grinding, just attach an electric screwdriver 🫡
