Details

Designed to be even more compact and travel-friendly than its big brother, the Feldgrind, the Aergrind still features the same 38 mm coated steel conical burrs and stepless adjustment. Now, however, those burrs sit inside dual bearing mounts in a unibody milled aluminum casing. As before, grind adjustment is stepless and built into the upper portion of the burr shaft. Holding the lid in place, you can change your setting by rotating the handle, with a cutout indicating the number on the lid's dial for reference. In total we find the ideal grind range is covered by the first 5 revolutions of adjustment, with each revolution translating to about 0.7 mm of vertical travel between the burrs. Espresso, drip, and even french press grinds are accessible, however the smaller volume of the hopper and grinds catch make the Aergrind better suited to smaller doses and single cup brews.

The Aergrind is purposefully designed to fit inside the plunger of an Aeropress coffee maker, making for a compact travel coffee setup. The hopper holds about 30 grams of beans, and the grinds catch holds about 25-40 grams at a drip grind (3-4 revolutions). For cleaning, we recommend wiping down parts with a soft, damp cloth and drying thoroughly, and cleaning the burrs using a pipe cleaner or similarly soft-bristled brush.

Immediately happy with this grinder!

Upon first turn, it is the smoothest turning manual grinder I have ever owned. It is worth the price paid, all other grinders I have owned have been in the $60 range and this Knock grinder is leaps above. Also really impressed that it can grind a turkish fine grind and the coarse grind settings church out really even particle size. Watch the video reviews on PRIMA to determine which grinder is best for you. I chose this one because it fits inside my Aeropress and my Cycling career has me travelling most of the year. The grinder was heavier than I expected.

Great, easy to use, and high quality grinder

The Aergrind produces a high quality grind in a small package, far quicker than I originally imagined. As long as you're not brewing more than 3-4 cups of coffee at a time for multiple people, this is a perfect grinder and terrific for travel. I'm more likely to use this than my Baratza Encore for the foreseeable future.

Great Hand Grinder

I went from a Hario Skerton since I was looking for a grinder that could do espresso and the difference is unbelievable. Very consistent grind and very sturdy design. Only negative is that since it's a travel design, the crank isn't that long and requires a decent amount of work to grind but much easier than the Skerton.

Great for Aeropress!

The grinder is perfect for use with the Aeropress. I have been using it about five times per week for the last two months. It is fairly easy to use and it is not that hard to grind. It takes about 30-40 seconds. As advertised, it fits perfectly inside the Aeropress when traveling. I was skeptical that a burr grinder would make that much of a difference in the taste. I have to say, the coffee is significantly better. I tried two different single origin coffees using a blade grinder and the Aergrind and the burr grinder made a much richer cup. I would not recommend it for people looking to make multiple cups of coffee as the grinder only holds between 25-30 gms.

Amazing Hand Grinder

I love this grinder! So glad I decided to invest a bit more and get an excellent quality grinder. (Originally was considering a Hario.) The handle does not have "knock" stamped on it like in the product photo. I prefer it without the stamp. Visually, it‰Ûªs very sleek. The build quality is excellent. It's very sturdy and feels like it is going to last forever. Uniform grinds even at coarse settings and fast. I'm a woman with medium-sized hands and I don't find the Aergrind difficult to use at all. It fits well in my hand and the amount of effort needed to crank the handle is easily managed. If I attempt to grind more than 22-25g of coffee, it's too much for the bottom compartment. Easily remedied by emptying the bottom part way through. I use it mostly for pour over or French press. Love the analog experience of hand grinding coffee for my cuppa each morning. The smell of the fresh ground beans wafting up as it‰Ûªs ground. There is a really satisfying way feel to the way it grinds.

Knock Aergrind

If you are looking for an exceptional burr grinder under $120, look no further. I love having a grinder that does not retain a significant amount of coffee grounds (much less than 1 gram). In contrast, my Capresso Infinity grinder required me to remove its bean hopper and central burr to remove any retained coffee grounds, which sometimes amounted to 3 grams. I mostly make pour over coffee, and the Aergrind's stepless grind adjustment gives my coffee much more clarity than my Capresso grinder. Be aware the Aergrind will generate a lot of static when grinding its first pound of coffee beans. After the first pound, the static issue goes away. Overall, it is a great choice for a manual grinder.

Getting good grinds thus far

I have a baratza virtuoso as my usual everyday grinder, however the person i live with does not work on tuesday and thursday so i needed something quiet to grind coffee on those mornings. Thats where the Aergrind comes in. I was skeptical of a handgrinder at first, but it really doesn't take much effort! 20 grams of coffee takes about 40 seconds to grind. much quieter than the virtuoso as well. I haven't put a whole lot of beans through it yet, so i am sure it will improve, but so far so good!

Scottish handiwork

i have only had my aergrind for a week or two; so far it has been amazing. Transitioning from a Baratza Encore, I am very pleased with the grind particle consistency; i am using his grinder for medium to large drip brews (V60 and Chemex primarily). Even 0.75L (~26.5oz.) brews are clear and timely, with no noticeable increase in choking the filter from my Encore. Stepless adjustment is great too.

Complete game changer for espresso

With the introduction of the Aergrind by knock, the entry level espresso world becomes a lot more accessible for everybody. There are no good espresso grinders out there under $120, and unless you want to take a gamble with questionable build quality by Breville, no grinders that grind the full range from espresso to French press under $300. The Aergrind is amazing for espresso and the stepless and fine adjustments let you really dial for your machine, something that can't really be done with the Baratza Encore in the same price range. I use around 1:4 to 1:9 on my old and cheap Coffee Gaggia and can pull shots between 20 and 30 seconds while my old Hario mini mill never got fine enough to break 15 seconds. Even if you're not using this for espresso, the grind consistency improvement over Hario hand grinders is huge, bringing out so much more clarity in every cup of pour over and Aeropress. The Aergrind has something for everybody who has been using a grinder under $50 and is looking to move up.

A very nice grinder

I purchased this grinder as a present for my coffee minded significant other. It's a huge upgrade over using an electric blade grinder in terms of grind quality, and a very cost efficient option over other burr grinder options. The size makes it ideal for a single-coffee drinker household. Performing the grind is pretty quick and painless. It comes well packaged and Prima shipped it quickly with plenty of time to spare before the holidays. The only downside is that the Knock came with no instructions at all; we had to spend some time to watch video tutorials / read guides on the Feldgrind and try to apply it to this model to get started.

Wonderful for making one drink

I was considering getting one of the bigger hand grinders (Lido, Knock, etc), but ended up buying the Aergrind this because I never grind more than 18g at a time for espresso. This option was also more affordable! This is a very compact, solidly built grinder. I have not noticed any wobble while turning the burrs, and grounds seem to be very consistent. Grinding my usual 16g of espresso takes less than two minutes of reasonably fast grinding - much less work than my old Hario Skerton. My only complaint is that removing the bottom compartment to retrieve grounds can be difficult sometimes. Overall not a huge issue, just adds a few seconds to the work sometimes. Overall, wonderful grinder for those who only make one drink at a time. For serving multiple drinks I'd go for one of the bigger options, but for my purposes this grinder is perfect.

Impulse and Regret

My Porlex mini had become a regular travel companion. Snuggled into my Aeropress, we'd head around the world together with some bags of beans and a couple changes of clothes. Hotels would become clandestine coffee labs as I learned and re-learned how to boil water with various different devices not meant for the job. And then I started hearing about this Aergrind and was consumed with an irrational lust. $100+ for a travel grinder? But the one I have was less than half the price works great. I mean it works well. Well, it works. The Aergrind kept tempting me, taunting me, but it was always out of reach and I didn't mind. But then Prima got some in. And Prima was having a holiday sale. And before I knew it there was a confirmation email at the top of my inbox and a growing sense of buyers remorse in my stomach? Did I make a mistake? When the Aergrind came the remorse immediately became regret. Regret that I had ever felt remorse. Regret that I had put up with an inferior product. Regret that I had ever doubted. Find an Aergrind. Hold it in your hands. It feels amazing. The quality of the craftsmanship on this thing resonates into your fist. It's a smooth grind, you can feel the power of those easily adjustable burs. Welcome to the family, little Aergrind. Let's travel the world together and jitter into adventure.

Very good value

Purchased to gift, but had to test before letting go. At a drip setting, med/dark roast, was very smooth grind, little effort needed, and quick. Took two loads in the grinder to fill the basket, but was still fast. With a bit of practice, should be even faster. There was a bit of static so the ground coffee was piled on the sides of the bucket, but a tap on the base and all the coffee came out easily. Very tempted to get another for myself, but SO suggests that three grinders may be enough for now :)

best travel grinder

just back from three weeks on the road with this grinder and I have to say that it is excellent and a major improvement over the hario I used in the past: better grind consistency and much easier and faster to grind. Highly recommended! I only used one grind for the aeropress so can't comment on its ability to change grind settings.

Best bang for buck

I bought this because I was in search of a quality grinder to meet my needs varying from Aeropress to 8 cup Chemex. I have a Baratza Sette 270 which I bought for my 30th birthday last year based on the manufacturer claiming that it could grind coarse enough for a Chemex. I have beer really disappointed with it, and have a very hard time not getting a bitter, and muddy cup. I am sure it‰Ûªs great for espresso, but I don‰Ûªt do espresso at home. I read the reviews about this little guy, and figured I‰Ûªd give it a chance because of the price point. This thing is amazing. I look forward to using it every morning. It takes about a minute of grinding at a reasonable pace for my 22g dose for my V60. The consistency is far superior to a Baratza Maestro plus that I retired a few years back. It cranks very smoothly. The first hang grinder that I ever purchased was a Hario Skerton. The burr wobble was terrible, and the burrs didn‰Ûªt have an agressive cut so it took like 5 minutes to grind a normal dose. The next hand grinder that I owned was the HandGround hand grinder. I had backed it on Kickstarter. It did grind much quicker, and is superior to the Skerton. I didn‰Ûªt like the ergonomics, and the consistency isn‰Ûªt as good as the Aergrind. The only negative about the Aergrind is the small capacity, but considering that it is specifically designed to fit inside of an Aeropress for travel Knock couldn‰Ûªt really do more. 22g is about max capacity for this grinder. Overall, I am very please with my purchase.

Excellent manual grinder

Tested the grind for aeropress, chemex and espresso and I'm extremely pleased with the results. The grind is very consistent with not many fines. The speed for grinding is pretty fast and not fatiguing. As many people agree, I wish the dial cap was made of metal. Otherwise, very solid and quality craftsmanship.

A Wonderful Manual Grinder at a Reasonable Price!

The quality of the build is exceptional - the shaft rotates easily and appears to be perfectly aligned without any apparent wobble. The parts are finely milled, fit together nicely, and are well designed. The burr spacing is easy to adjust and the handle attaches without much effort and remains in place during the grinding process. The operation of the grinder requires less effort and is considerably more refined than that of the Skerton (non Pro model). The consistency of the grind was comparable to a Baratza Virtuoso. I have not used a Lido, but I am very impressed with the Aergrind. I generally defer purchasing new products until the initial production problems are solved. The product is well packaged in bubble wrap within a cardboard tube. Usually, I can identify flaws or dislikes that I would suggest be corrected in future versions. The only flaw that I have identified is the lack of instructions. However, there are Youtube videos that explain how to adjust the burrs. Finally, there are extra O rings that are included with the grinder.

Significantly better than my previous Javapress grinder. Great for travelling with my Aeropress. I wish the hopper just a bit more capacity and that the Aeropress funnel fit neatly inside the hopper during bean transfer. Otherwise, excellent build and grind quality.

Hard to find instructions.

Just got this grinder for my travel aeropress kit. Overall, I really like the grinder. I have only been using it about a week though. I can fit about 27g of beans in it but they fit right to the very top of the chamber. Sometimes the lid doesn't go all the way down but a few spins and it closes up. It is solid and well built. The only plastic part is the lid but it doesn't really have any tension on it to cause breakage so I think it will last. It can grind very, very fine. Main issue I had is the lack of instructions. I had to dig around the net to figure out how to use it. The company that makes them doesn't even seem to have anything on it. Also, the info I found around the net on grind settings for pour overs to be way too fine. It was so fine the water could barely pass through it. Your best bet is to spend 30m grinding beans at different settings and comparing them. It helped me figure out fine-medium and now I'm dialing it to what I want vs the recommendations I found. Only other thing that would be nice is if the 1 on the dial was white so it was easier to tell when you made a setting rotation. But that is easily remedied with a silver sharpie. I am really happy with the purchase and prima shipped if really fast even when it was on backorder at my time of purchase.

Knock Aergrind

The Knock Aergrind is a fantastic product. After doing preliminary market research on hand grinders, I was excited to snag one from Prima for a great price (and blazing fast shipping). First off, the grinder feels great in one's hand, albeit a bit small. Grind adjustment is very simple and seems quite stable. Very portable and ergonomic -- no complaints here. The construction and housing of the burr set is solid. Operation is very smooth and it grinds much faster than my old Hario mini mill. Particle consistency is a big upgrade from the Hario as well. I use the grinder for drip coffee, and I have had great results thus far. The only "knocks" on the grinder are: -small capacity: ~25g of coffee, depending on bean size -at a filter grind setting, it produces a fair amount of fines -- enough to choke the filter towards the end of extraction -flimsy plastic cap; after a week of use, the cap has loosened and can fall off if not held in place by the handle -grinder arrived not fully calibrated; the zero point of my unit started at the number 2. A small detail, but hopefully Knock can iron this one out in future production/QC Would recommend for anyone looking to upgrade their grinder without it costing an arm and a leg. There's something satisfying about manually grinding your bean. Great value, shoutout to Prima for their great customer service.

Works great but the lower half seperated

This is an excellent grinder but I fumbled one day and dropped the lower half on my countertop. The silver disc engraved with the Knock logo seperated from the remainder of the lower half. I understand that I dropped it but I can also see the remnants of the adhesive used and it did not appear to be consistently applied.

Average

Grind is good except for coarser french press grinds -- quite uneven. Lid is loose and grinder won't zero-out and calibrate as it was designed to do. Additionally, Knock provides no support. I would not purchase anything from Knock again. Peter Kilpatrick does not respond to the form on his site, email, Facebook or Instagram. Unfortunately, Prima will not provide his phone number, even though I purchased the grinder through them.

Knocking Knock

Knock makes decent -- not perfect* -- grinders but rips off customers. Still waiting for a refund for a grinder I ordered in December and he never sent. Called Prima to complain and they would not provide contact info. Lots of complaints online about Knock. There are better grinders out there and Prima should find credible suppliers. *Top lid becomes loose with minimal use

Be wary, be very, very wary.

I understand that the Felgrind has received quite an amount of praise for it quality of grind among its owners. I also understand the assumption that the Aergrind would be more or less a smaller slightly less feature rich version of the Felgrind. However it is not. I ordered this with the first batch Prima got on Nov, 24 and as such, am beyond a return. But to speak plainly to you, with all due caution, I absolutely loathe this grinder. It looks, great, it feels solid and it "feels" like a great grinder. However, the grind you get is all over the place. I primarily do pour over (V60, Kalita) with an occasional Aeropress. Even at these relatively fine settings the grind I get is inconsistent to the point of being on par with, or much worse than a Skerton Pro. My Aergrind arrived with it's "zero" mark being 2:1. Not a huge deal per se but you cannot adjust this to get it to actually be "zero", and if you search around you will see people have received them with their "zero" ranging from 1 (good) to as high as 7? And this, is where the signs of quality control concerns begin to arise. The cap for mine (with the number marking used to measure adjustment) does not sit flush with the top of the grinder, and if you touch it at any point it will teeter-totter on the top of the grinder. In using the grinder, the settings I have adjusted to will change (loosen) during the course of the grind. This is while doing small batches mind you, so say I am set at 2:12:1, when I have ground 16g it may be at 3:1:2. You can see why that might become an issue. After all, you bought a "good" grinder namely for improved consistency correct? All in all, if I were able to return it, I would have with no regrets. And I labored over writing such a scathing review, but, I feel like this product is more beta than complete and if I could do it again, I would skip this and get either a less expensive grinder so that the quality of the grind is offset by the price of the grinder, or just bite the bullet and buy a Lido. TLDR; I'm stuck with it, to warranty it is to ship it OCONUS, wait for a looong time and possibly end up in the same situation again. Too late to return it (Holiday travels ruined the time frame). It has quality control issues. It grinds inconsistent even at relatively fine grinds (don't even dream about a usable French Press). The grind will change in the course of grinding as little as 15g, and will be massively different in 4 to 5 days of grinding.

Obvious Improvement

I spent years with a Hario Skerton. I was reasonably happy with the coffee I was making and put effort into the rest of my brew process to try to find improvements. But, I finally decided to try putting my.skerton grounds through a sieve and the inconsistency I was getting was way worse than I expected. Brewing with the boulders and fines removed made such a huge difference that I took the plunge and bought the Aergrind. The improvement in my coffee is immediately obvious. This is truly a “throw money at the problem” kind of situation. If you are on this website then you probably already have self selected and are the type of person that cares enough about your coffee to consider this grinder spending this much on a hand grinder. Congrats. That was the hard part. Once you spend the money it is all easy from there. The grind process is smoother and the results are just better. The only downside is the capacity. The grinder holds about 75% of the beans that I wish it did so every brew I have to fill it twice. If I were buying again I would give up a little portability and get the bigger one.

Oh! I can get a new rubber band to hold the handle!

This is a followup to my review from a couple days ago. To recap, I regret stretching the rubber band that affixes the handle to the grinder in order to fit it onto my Aeropress. It turns out I prefer to have it affixed to the grinder. And since I can't un-stretch it (I tried the boil it trick. It didn't work), I thought I was out of luck. But Peter sells replacement bands on his website, It's pricey due to the cost of shipping from the UK. But I'll take that as penance for my lack of foresight. And now I'll have the best of both worlds.

Perfect for travel, and excellent for everyday use

I purchased this for travel to use with my Aeropress. I now often use it for everything except espresso. The only reason I don't use it with my espresso machine is because I'm lazy that it takes too long to dial in a manual grinder, and because I have a Rocky for that purpose. I compared the grind quality to the rocky at espresso and Aeropress grinds, and found them to be equally consistent. And the Aergrind did not have Rocky's characteristic clumping at espresso grind. I find the Aergrind is less consistent at courser french press grind (about 4-0). But no less consistent than the Bodum Bistro I normally use for that purpose. I've been using the Aergrind for almost a month now. I have not experienced any drift of setting whilst grinding as others have reported. Maybe that's due to the new aluminum cap. Whatever the reason, I've never had it happen. My only complaint, and it's more on me than on Peter, is that the rubber band used to hold the handle cannot be reused on the grinder once it's been stretched over an Aeropress. I tried it out on the Aeropress, found that I prefer having the handle affixed to the grinder (I know, then I can't slide it into the Aeropress body. But I'm not so chuffed about that.). With it afixed to the grinder, the knob of the handle acts to keep the aluminim cap from falling off. But now that I've stretched it, I can't go back. If only I could buy a replacement band, then I'd want for nothing.
