Compak understands that sometimes power and amazing functionality simply are not enough. If you're going to shell out for a pricey piece of coffee hardware, it should look good too. That's why the company created the K3 Touch Advanced Doserless Grinder. The K3 is ideal for home or light commercial use and features a large coffee bean hopper that's designed to prevent jamming, an easy-to-clean ground chute and settings for single, double or constant grind quantities. As for looking good, you'll notice the K3's clean lines and attractive design are leaps and bounds above most other mid-range grinders on the market.
Features & Functionality of the Compak K3 Touch Advanced Doserless Grinder
Stepless Grind: Stepless grind adjustment makes it easier than ever to make tweaks to the fineness of your grind without complicated adjustments with tools.
Multiple Dosing Systems: The K3 features single, double or continuous dosing systems with a twist of the easy-access aluminium handle.
All About Beans: The grinder is designed to operate using minimal RPMs, which means that the 58mm flat burrs stay as cool as possible and do not transfer excess heat to your roast. The hopper holds up to half-a-pound of beans — more than enough for home or light commercial use.
Keep It Clean: The design of the K3 makes cleaning the bean hopper, ground chute, and grinder a snap.
Form Matters - The K3 has an impressive and attractive design.
Stepless - With a quick rotation of the hopper lever, you can easily advance beans.
Save Jams - Many other similar grinders are more prone to jams between the hopper and grinder. That is not the case with the K3.
Smaller Hopper - While the half-pound hopper is great for home use, it might be too small for cafe use.
Fixed Position Tamper - The fixed position tamper eliminates a bit of space under the ground chute.

Best Answer:Absolutely! This coffee grinder has been designed using the latest computer and engineering technology.The result is a high quality product offering exceptional grinding and dispensing capabilities. You will definitely be able to dial in your grind to just the right setting with this grinder!
I have heard that this grinder has undergone some design changes fairly recently along with a slight name change (now called the Compak K3 Touch Advanced on the Compak website.) Is the model version being sold here the newest/most current version available?

Best Answer:Yes, I double checked with our supplier and we are currently offering the Compak K3 Advanced. Thanks for the heads about the new listing and we will update the site to reflect Advanced right away!
Best Answer:I have the Model 58X400 Polished Advanced. It has the Timer knob on the front. It has a switch to select Timer or Manual on the lower Left side of the base and an On/Off switch on the lower Right side of the base. A single push of the discharge shoot with the Timer mode selected will nominally deliver a single shot of grinds. A quick double push will deliver a double shot. In Manual mode the grinder will operate as long as the On/Off switch is in the ON position. While researching grinders I read a lot of comments about the poor location of the switch on older models, and that the newer models have the timer knob on the front. I can't answer specifically about the 58SB400 vs. the 58SB200. I have had my 58X400 for just over a year now and I rate it as one the best purchases I have ever made! That's not just coffee grinders or home appliances I'm talking about, dollar for dollar the 58X400 is just EXCELLENT! Good luck with your search for a great grinder. Bob
I don't know that one is better than the other, but I believe the one with the front knob is a newer model. I own two of these... one without the timer and one with the timer. I think it would be considered personal preference rather than one being better than another. I use my grinder at home and I only make one coffee at a time. I suppose if you are multi tasking and would like to walk away from your grinder while it grinds, then the front timer knob would be very useful. My common sense opinion is that having the front knob feature easily accessible and in plain sight is much more efficient and useful and gives you more options as to how to use it. I really like both of my models and that's why I bought another one for my second home. It just happened to have the front timer/knob. It's a great grinder!
My understanding is that the old version of the grinder had the timer adjust knob on the bottom (very inconvenient). You can see it in the video. The new (current) version has the knob on the front. I've only used the version with the knob on the front, but I've used the knob so many times that I know I would be unhappy if it was on the bottom.
The timer knob in the front is the newest model. The timer knob for how much would be ground was underneath the machine in past models. Much more convenient on the newer models but I really don't find it that useful as I go by look.
Mine has a knob in front and I assume the other model has the knob on the side or another location. It sets the time that the grinder runs and fills your potafillter. I actually weigh each dose and don't use the timer.
I have the timer on my K3. Once it is dialed in with the proper grind, it gives me a consistent espresso. It took a little to get used to but now that I have experimented with the timer I really like the option.
I just got my K-3. I'd like to adjust by number but it's completely unclear where the adjustment point is. i.e. I see the grind numbers but I don't know how to set to to, say, 38. Where do I put the number 38? There's no indicator on the machine as to where a number should line up with. Any idea?
Best Answer:Essentially, there is no number scale for this machine. If you hop on youtube and watch dosing guides from Gale, you will see how to dial in your grinder. My advice is take it all the way down to where the burrs touch, bring it back off, and then just go coarser as you proceed. Also, remember.. Each bean is different and will require adjusting as well. Again, there is no way to say "I set mine to 38," -- it is just based off dots, and that is no guide at all. Welcome to the world of stepless.
Hi Jordan, I go by the dots below the post. Among the dots is a coffee bean and I adjust so the post sticking out the side is one dot to the right (slightly finer) for pour over and another dot+ for espresso. I totally ignore the numbers. Also, there is a noticeable difference in grind with even a slight adjustment. Tony
Then why did you buy a stepless grinder? If you want to put numbers on the grinder, then you'll have to do it by hand. What you want to do is dial it into the general espresso range and then number it around that area. I don't really see the point in numbering, though.
The numbers are just guide points. They aren't supposed to be lined up to anything or set in a specific spot. The grinder is set to "38" whenever the little pointy part of the adjustment collar is lined up with the number.
Unfortunately my wife prefers decaf and I am not sure if I have to buy two machines because of that. Would it work just to exchange hoppers say two times a day? Would this work?

Best Answer:The hopper is easy enough to remove, but the beans will drop down into the area around the burrs each time you open the flap at the bottom of the hopper. This flap is what would allow you to close the hopper and replace it with another with the beans inside. You would have to grind whatever fell down into the burrs during a switchover. This could waste the equivalent of an entire shot each time you change.
I actually don't store beans in the hopper. I keep them in airtight containers. I've found that if I weigh out my beans prior to grinding, I get about the same amount out that I put it. It seems that I only lose a max of a gram. Closing the flap on the hopper helps keep the small amount of beans from getting thrown around too much by the burrs. (This process is how I know that you'll have about 20g of beans between the flap on the hopper and the burrs.) Just need the space to keep a scale next to the grinder. Hope this helps!
Yes, I belief so, at least for the same grind density. I home roast and only use caffeinated. I actually bought a second hopper (easy to find), for a different reason -- I wanted the shorter, smaller hopper because I home roast in small batches. I needed the shorter one also because I keep the Compak under my kitchen cabinets and the stock hopper is quite tall.
One thing you should factor in is that whey out switch hoppers, there may be a few beans in the burr area, but I just put a small cup under th spout and grind them down if I'm switching roasts.
You didn't ask, but I'll tell you this grinder is terrific. I had a Rancilio Rocky doses less before this and it pales in comparison. The Compac is excellent.
If you're going to be grinding two different types of beans during the day, and only have one grinder, then you should just grind only the dose you need each time. Don't fill up the hopper with beans - just put in the exact amount you need to grind each time.
A reviewer mentioned a design flaw with the hopper cracking where it meets the machine. He mentioned having to order 4 total in 2 years. Have you noticed this flaw? What if any prevention is there? Has this been remedied in current designs by Compak. If not is it covered under the warranty?
A shopper on Oct 7, 2013
Best Answer:I have been using mine every day for about two years and have had no problem. I did, however apply a one inch wide piece of 3m painters tape along the bottom edge of the hopper to snug up the fit so that it doesn't rattle at all and fits very tight. I only remove it every several months for a good cleaning.
Best Answer:No, we do not offer a canister to collect coffee that is compatible with the Compak K3, and the step less adjustments of this unit mean that it would be a bit of a hassle to change back and forth from espresso to pour over. A better grinder for your needs would be the Baratza Vario or Baratza Vario W. These units handle espresso to pour over grinding very well, offer stepped grinding adjustments to easily get things dialed in, and the grounds bin holds about 5oz. As an additional feature, the Vario offers a portafilter holder for espresso as well as a grounds bin. The Vario W offers just a grounds bin but also offers a weight base to tare out and then grinds a specific weight into your container. Hope this info helps!
Ok, so our labs compak k3 hasnt been cleaned in a while.. causing the top to be stuck on there after following manuals directions to remove the top burr. What can we do to clean it or release it? I think it is gunked up a bit making it hard to remove. HELP!

Best Answer:You might want to try running Grindz through the grinder to remove some of the oil build up, but if the grinder is severely blocked, it may need to be serviced, unfortunately. Grindz can be found here:
I've had this grinder for just over 6 months and believe it to be much better than the Rocky grinder... See details here - !

K3 RocksReview by Swblee
Prior to K3, I had a Rocky grinder. I wanted a finer adjustment on the grinder. I picked K3 based on the reviews. K3's grind is noticeably more consistent and less clumpy. K3's motor is much quieter. I was happy with my Rocky. However, K3 is definitely a grade above that worth every penny. It makes my Rocket Cellini purrs. (Posted on 8/17/2015)
8 Months In ReviewReview by Daniel
I've had this grinder for 8 months now, and here is what I think so far.
At first this grinder was insanely overwhelming as I'm coming from a Breville single boiler machine with the crappy built in grinder.
For me, I don't ever use the timed dosing.
The most important piece of equipment I've purchased isn't this grinder or the Rocket machine. It's the $20 scale that allows me to weigh my dose, and my extraction.
Every bean grinds different, isn't the same size and especially doesn't weigh the same. So please do not base your dose on the fact that you're filling your basket.
I love the stepless design, with the Rocket machine it really requires the perfect grind.
The difference in grind becomes pretty small once you dial it in, so don't worry about having to adjust it every time you buy different coffee.
One of the downsides is when you're running low on coffee, this grinder seems to become really inconsistent since it doesn't have the weight of all the beans pushing down on them. (This is probably the same story for every grinder) Try and keep that hopper filled as much as you can!
Wish the hopper had a nice air tight cap on it, but it's all good considering the price of the grinder. (Posted on 8/7/2015)
Performs well!Review by gjskandy
The Compak K3 Touch looks great and performs well. At half the price of the Mazzer, it does everything required to provide consistent grind and dosing (timer). I've had practically no waste. This grinder is a great value. Make sure to watch the SeattleCoffeeGear videos on the Compak K3. The manual that comes with the grinder is pitiful. (Posted on 5/15/2014)
Wonderful Wonderful!Review by PEP SLC
I have had a Rocky grinder now for 3 years and have moved that grinder to my office and replaced it with the Compak K3. Well worth the extra money over the Rocky if you have the space - it is a bit bigger. I ordered the polished aluminum version and was a bit hesitate - but am very pleased it looks FANTASTIC!
And beyond looks I love that it has infinite settings - and most of all the auto dosing timer is great. I followed the instructional video online and it is very easy to set up and I get a consistent grind and the exact 7.5 grams or 15 grams with either one touch or two quick touches every time! It is also much quieter than most other grinders. So far a GREAT investment! (Posted on 3/18/2014)
Great Home Espresso Grinder Review by David
I just bought this to replace my trusty Mazzer Mini, a grinder that will outlast us all, however this is quieter, prettier and more convenient with less wasted coffee, for half the price of the Mazzer with electronic dosing. I am very happy with this grinder overall, easy to set up. Manual is very bad as with all espresso equipment I have purchased. (Posted on 2/22/2014)
Great grinderReview by Elliottok
This is a wonderful grinder. Making it even better is the fact that the design has changed - the timer adjustment is now on the front of the grinder instead of underneath the grinder. Makes it a A LOT easier to adjust your timed setting. Seattle Coffee Gear should update their photo/review to show the new design. (Posted on 12/18/2013)
Great grinder poor hopperReview by Greg
I have owned this grinder for over three years. The grinder is easy to maintain, fits well under my counter and does a good job on beans. I have used the Preset doser and after a little calibration works well. The grind adjustment is sensitive and does not have to be moved much to change grind. My only complaint is with the hopper. I have just ordered a fourth new hopper since I purchased the machine. The plastic collar that fits into the grinder fractures after 8 - 12 months. I take excellent care of my equipment and feel this is a definite design flaw and not a user problem. (Posted on 12/1/2012)
