“coming from a dying, increasingly inconsistent Wilfa Svart electric to this manual grinder has been a revelation - the K6 grinds SO much faster than I was expecting!”
“Clicked on the QR code and got zero helpful instructions. Didn’t even link to the K6 product. Tired of buying things that don’t even have a designed user experience.”
“K6 is good once dialled in, but I find if I stray too far from my sweet spot (34 for my caffeine beans, 31 for my decaf) then the sweet spot has drifted when I return.”
“Turns out it’s loads better than the smaller models. Grind quality is a step above. And it’s been giving me consistently great coffee. I’ve got zero buyers remorse”
“Had same issue. I think seemingly small differences in angle, grind speed, etc. make a big difference to both fines production and overall size.”
“I got mine like 8 months ago and got the rust issue. They wouldn't honor the warranty because it looked like I hadn't cleaned it, but it got rusted shut within 4 months of owning it, so I never cleaned it”
“I think the build is weak; everyone had the problem of the rubber grip coming loose and detaching from the grinder body, and the K4 and K6 broke the handle knob. (Translated from Portuguese)”

“Wow! there is more clarity right from the start(?*) since there are less fines, that result in less clogging, the pour seems to be faster as a result”
“My current K6 (bought a month ago) works well between the 31-35 clicks range with about 16.5 to 18 grams of coffee.”
“Get the k6 and don’t look back. It’s great, and very easy to use. I tried the cheap small grinders from Amazon and they were awful. K6 is awesome.”
“I'm running 45-47 clicks on my k6 with the Ruta Maya medium roast from costco and have pulled great shots”
“Used k6 for less than a year daily and the handle knob came off, the rubber grip is displaced making it unusable.”
“Just got one last week and it is amazing, no o ring swap for me either, and it has elevated the aeropress experience”
“I like mine for a travel grinder but it has static issues I never heard of before buying. Like bad.”
“It got old fast for me and I wish I had gone straight to an electric and skipped the manual.”
“I found it to have better brews for that specifically. If you’re doing espresso it’s a non-starter”
“For espresso, I'm sold on the K2/K3/K4 burr design over the K6.”
“I have a k6 and love it. Very easy to adjust grind setting, grinds beans very fast. You will be very happy with it.”
“I got one until I can afford a decent electric grinder or see something pop up on marketplace”
“it feels like going from a toy to an actual tool. I love it, feels premium and the cups are sweet and balanced.”
“I have a K6 and I really struggle with consistency”
“I have the K6. I'm impressed with the build quality and results. It's efficient and easy to use for pour over”
“Maybe I wouldn't be so quick to definitely blame it on the grinder. I have the same grinder.”
“I have the K6 and cannot confirm. The external adjustment works fine and never interferes while grinding.”

“I am like -6 and I do 90. I also get 2 mins on all of Lance's brews. I find if I go even to 80 the brews are way too over extracted. 90-85 seems about right everytime. Cafec Abaca.”
“Thanks mate, I decided to go with the method you suggested and had my first brew this morning (french press) It was great but I had an issue with grinding the beans at 150 clicks.”
“I haven't cleaned mine yet because of seeing videos of how hard it's to put the pin again. I was thinking of getting grinder cleaning tablets but unsure if they work with manual.”
“Apparently the unit the famous YTer got was the type from AE that came without packaging etc, and did not include O rings at all. Mine came from AE with packaging and O rings.”
“Hi pax I seem to be getting very empty brews with my k6 I got last week, no notes on taste but there are some on the nose I've been down at 60 and up to 110 with Timemore b75”
“Almost gave up cleaning my K6 because of this clip! I used the sharp point of push pin to lodge it out. I don't disassemble the K6 anymore, just stick the brush in and out every 2-3 grinds.”
“For anyone wanting to reduce fines, RDT + slow feeding is the way to go. I've personally noticed a huge difference between rdt and no rdt when it comes to producing fines.”
“Hopefully not off topic but when I was cleaning the burs I lost the little U locking nut and had to use up the spare that came in the box. Anyone know where to buy extras?”
“It does 4 full rotations. You are miles from 0. Once you get to 0 keep turning until it physically stops. That is your true 0. I find espresso about 40 clicks above that”
“I have a new K6 and I use both the rings. There is absolutely no problem with the white ring coming out. I get a snug fit and the handle always stays in its place.”
“Dici? Se non ricordo male la mini guida compresa nel k6 indicava 95 click per v60, che per i miei gusti è comunque un po' troppo grossa. Di solito io sto sui 75”
“-5 burr lock, ~80 clicks, lance 2 pour recipe gets me 2 mins with Cafec Abaca, depends how fast you pour and how much you agitate I guess. And also the beans.”
“I found pliers to be essential. Maybe if one has longer fingernails, but I found it impossible without tweezers. (What I wouldn’t have given for a hemostat.)”
“Intersting… I got myself K6 recently, I'm brewing with Origami, and I ended up at 120, cause with 90 (or even 105) I had a pretty strong cup of coffee :eyes:”
“When grinding too fine with the k6, I noticed a loss of flavor. It would be thin and muted. Try a coarser setting. I start around 90, but don't be afraid to go coarser. Not sure if you're still needing help.”
“By controlling the heat, try to avoid the sputtering at the end. This makes less coffee by volume than I used to make, but I add hot water after, and even without the filter it makes a much more balanced brew”
“Thanks for the explanation, much appreciated! One question - after removing the black ring and installing the white one, I’ve noticed that the PC lid is rotating along with the handle. I assume this is correct?”
“Sorry to ask this again but I just received my K6 today, and like many, my zero point is actually +8 clicks. I understand what you mean by 60 clicks will always be one rotation or round regardless of zero point.”
“Guys, I think I'm having a lot of fines with my K6. I'm clogging the v60 at 90 clicks, 20g to 350ml (60, 160, 130) and it takes 5-6min. I need to know if it's about the grinder or my technique.. any tips on that?”
“I make 2 shots every morning and spend a cumulative 3 minutes trying to figure out the secret combination of smacks to release all the coffee. I’ve had the grinder for a year and a half. I think I’m getting close.”
“I managed to pry out the black one with a very blunt knife, but having installed the white o-ring, I'm now struggling to get it off. Any tips?”
“Probably more than a notch. Maybe change the setting to 30? For my kingrinder K6, I remember grinding VERY close to the lock point of the grinder for some espresso's. Like 10 clicks from when the grinder would just lock”
“I usually tap my K6 three times on my hand or a soft surface, to knock the majority into the catch cup. But I have noticed that it appears to mainly consist of fines, so discarding could be the way to go... Interesting.”
“Just got a K6 and mostly use Chemex. I think that 160 clicks recommendation might be an error? Threw out a batch I made with 120 clicks but had pretty decent results around 100 clicks. Gonna continue to dial it in but just flagging!”
