Rated 5 out of 5 by from Amazing little beast! This is an AMAZING little grinder! I got it because I travel a lot and am seriously addicted to good coffee. I wanted something to use out on the road that was also small enough to pack when hiking. This goes way beyond that and I find myself using it everyday. There are very few proper ceramic burr hand grinders. And the only one "intended" for camping use is the GSI Java Grind. It is big and heavy though and not a good choice for backpacking. This Hario Mini Slim on the other hand fits easily into my pack. Grind consistency is awesome. It is a mild workout, but is still fast and easy to use. I LOVE this grinder!

Rated 5 out of 5 by from Actually performs as advertised! This is a clean, compact, simple design that is easy to understand and to use. If anyone is worried about the minute it takes to grind the beans, he or she probably does not like coffee enough to appreciate what this little gem does. It takes longer to boil the water than to grind the beans, and this will easily grind enough for two very strong cups. I like my coffee strong, clean, and clear, and that is what the hario delivers. Kudos! The only suggestion: have an English speaking person edit the directions.

Rated 4 out of 5 by from Works well I've been using this for at least a month now, and overall it works really well -- I'd give it a 4 1/2 stars, but the site won't let me. I'm using it for a french press. For the price point, you won't find anything better. There are just a couple of small negative things, namely that using it for a large pot can make your wrist hurt a bit and you do get a noticeable amount of smaller grind. Both of those issues are not a dealbreaker overall and if I was that concerned with it, I would've bought something way more expensive. This is nice & quiet, it does a good job with the rough grind, the beans stay cool, and it uses no plug-in energy. If you want to change the size of the grind, it is very easy to do so. For me, the positives outnumber the negatives by a wide margin.

Rated 2 out of 5 by from Would be great save one major flaw I bought this at the end of last year and used it probably 4-5 times a week for grinding my own single serving of fresh coffee beans. Lasted round 6 months. On the plus side, it's very easy to dial in the desired grind settings and not have to change or adjust. Relatively easy to use and only takes around a minute or so to grind a full hopper of beans. It does give pretty consistent grind sizes. The one flaw that's a deal-breaker is that the top hex nut that the grind handle attaches to is of a softer metal. Over time, as some other users also have noted, it will wear and cause the handle to stick and eventually strip entirely rendering it useless. Sad that a premium brand like Hario would have a high friction piece on the grinder be so low quality of metal. I can't recommend this product unless your intended use would be limited, like as a backup or for travel. Not for daily use unless they've recently changed their design.

Rated 5 out of 5 by from Adjustable and reliable I bought this to produce an espresso grind. Very first shot I pulled using this grinder yielded the best shot I ever got out of the Gaggia. Enough said. I like it is made of plastic, easier to transport. The mill's handle gets stuck on the unit sometimes, but if I simply pull up on the end of the handle, it frees itself, so I can remove the lid. All in all, very pleased with this purchase.

Rated 5 out of 5 by from Beats Skerton Every Time IMO Note: I used to work as an employee at Prima Coffee but the following opinion is my own. I had used the Hario Skerton for over a year for my coffee and appreciated its quality and use, but there were several annoyances. I recently got ahold of a mini mill and after using it for a couple of months would never go back to the Skerton! They seem like small things, but when using it often, the differences are substantial for me: A lid - oh how wonderful to not have my beans peppering my kitchen while I grind. This was my single greatest annoyance. Easy click grind setting - I love not having to take apart the handle mechanism to set the grind. The spring in the burr mechanism - there appears to be a spring of sorts to keep the burrs tight as opposed to the Skerton which would promote a more uneven grind as the burr hangs loose. The skinny design - I can actually grasp the HAND grinder with my (not terribly large) hand and crank on it, even if held on its side (with the lid preventing beans from falling out). Quieter design - this may have to do with the lid, but overall, the Mini Mill is IMO substantially quieter than the Skerton. You may not care about this until you are trying to grind coffee before work while your wife and toddler sleeps in the next room. I have a Baratza Encore, and I find myself actually using the Mini Mill quite a bit because of this. Grinding up 18g is hardly difficult while the water is boiling. I have been using the Mini Mill more than I thought for this reason. Over all, I'd say the Minimill, while not the ultimate grinder, is a fantastic little buy for the cost and I would purchase it over the Skerton for sure.

Rated 4 out of 5 by from Good little first grinder This is my first burr grinder. It gets the job done well at a fraction of the cost of electric grinders. I don't mind smaller batches and longer grinding times. I'm not terribly impressed with the grind consistency above 10 clicks. Large bean chunks make their way out at these settings. This makes French press difficult unless you are willing to change your brew time to accommodate a smaller grind. I prefer a setting of 8 clicks. This produces a medium-fine grind that works well in my aeropress. Settings below 8 are fairly consistent from what I can tell, making this decent for espresso as well.

Rated 4 out of 5 by from Quality you can feel! When you pick it up ... you can feel the quality. One turn of the handle and you feel no resistance until you drop the freshly roasted beans inside... then you just hear and feel aromatic yumminess dropping into the clear cup below. It is small enough to travel well.. I pack it , some beans and my Keurig strainer cup into a gallon size zip lock and drop it into my suitcase . It has the quality of the $100 plus grinders but for much less. Since it's made for only two cups worth of coffee groundings at a time. The manual grinding is well worth it.

Rated 5 out of 5 by from Everything excellent Prima is the best! First, the website is great. Filled with info and very easy to read and negotiate. I was trying to decide between 2 grinders, so I called for more info. The guy was really helpful and friendly and made a couple of points I hadn't considered. The grinder I bought was perfect - the Hario Slim. Price was competitive, shipping rates were fair, and it was quick to arrive. I had one final question for them and I got another guy who was knowledgable, friendly, patient and funny. This is the place to buy coffee gear!

Rated 5 out of 5 by from Great for the price This little hand grinder is amazing for the price. Grind size is a little inconsistent, but that can be improved by easy mods and making sure that you put the base of the grinder on a flat surface covered by a towel (or something else like that) to decrease the vibrations and jiggling of the beans in the hopper. This stabilizes the grinder, as opposed to grinding with it in the air and only being held by your hands. I was also expecting it to be harder to grind the beans by hand, but it actually takes very little effort to turn the handle! Once I turn on my kettle, I easily finish grinding before the water is ready. One of the only drawbacks would be the relatively small capacity of the container which holds the grounds. This would only present a problem if you want to make more than a couple cups - and even then, it isn't much of a hassle to empty the container and continue grinding. All in all, I would say that this grinder is great for the home brewer who doesn't want to spend $100+ for an electric burr grinder.

Is the grind fine enough for a commercial expresso machine?

Asked by: Ellie
Possibly, but that sounds like a nightmare!
Answered by: Rfelb
Date published: 2015-05-26

Picked up one of these for the office. I'll be using it with a Clever Coffee Dripper. Any recommendations on a grind setting to start with?

Asked by: pfunk
Grind size is greatly dependent upon your dose. Smaller doses require finer grinds, and larger doses require coarser grinds in order to control the percolation of the water. The Clever, like other full immersion brewers, is flexible because brew time is not dependent upon grind size and pouring technique. The user decides when to end the brew. For that reason you can use literally any grind size. Consider that coarser grinds require more time to extract, and smaller grind sizes require shorter times. It's difficult to communicate grind size and proper brew time because there are so many factors. It's best to experiment!

do you need to replace the burrs after prolonged use?

Asked by: Nikfizz
Good question. All burrs will wear down eventually, but it does take at least few years with heavy use. Replacement burrs are not available for this grinder, so at that point, you would need to purchase a new one.

Where is it made? Thanks!

Asked by: DWhite
This is actually made in China. When I unpacked and saw the (hard to remove) label that said made in China - I thought how ironic. That said I do like it though am having trouble now as the handle is hard to remove after grinding. Still a great value.

is the plastic high grade and bpa free?

Asked by: par87
Hi, Par87. Thanks for the question. The Hario grinders are not advertised as BPA free. Also, We've very rarely heard of the plastic casing breaking under normal conditions. Hario is known for raising the bar when it comes to quality!
