Incredible power. Unrivaled finesse.

Welcome to the grinder era. In 2013, we witnessed mind-blowing competitions, brain-busting blog battles, and game-changing new gear. And the EK43 got it all started. Mahlkonig's famous grinder has been in the shadows for years, but it's recently sprung into the spotlight and shown its worth. What about this machine makes for such a bright future?

Consistency. The EK43 boasts unmatched particle distribution – that is, consistency in grind size. This means fewer fines, improved cup clarity, and the opportunity for higher extraction yields without bitterness.

Versatility. Sporting stepless adjustment over a wide range, the EK43 is suitable for all methods of coffee preparation. Switching between recipes is easy with the numbered dial and you can even grind for large batches or customers' purchases with the handy bag clamp.

Power. With 98mm burrs and a motor that harnesses the power of almost two horses, the EK43 is unparalleled in performance. Your coffee will go from beans to bits at a rate of 21-25 grams-per-second, or 2.8-3.4 pounds-per-minute.

Rated 5 out of 5 by from EK43 My name is Ryan, and I manage the customer accounts here at Prima. I recently added the EK43 to my own brewing arsenal, and I couldn't be more satisfied. The rumors are true - this grinder will take your brewing to a new level. The difference in uniformity of grind is so drastic, you'l find that your trusted brewing parameters will need to be re-examined. It will change the way you brew coffee.  One thing I love about the EK43 is how little coffee it retains after grinding. A couple knocks on the bag clamp, and you'l find that only .5g-1g is left behind. Especially for a commercial machine, this is impressive.

Rated 5 out of 5 by from Fast, quiet and consistent! We purchased this grinder for our tasting room and training center and it's immensely helped improve cup clarity and flavor. It's grind particle size is extremely consistent and it doesn't hurt that it's a surprisingly quiet grinder as well, you don't have to pause conversation while the grinder is running. Would highly recommend!

Rated 5 out of 5 by from One amazing Grinder. It is true it is all true, well all the good stuff at least. You really can do almost anything with this grinder and achieve amazing results, form toddy to espresso all on one set of burrs. The consistency is unrivaled, and Ive tried them all. This is a can't miss grinder.

Hi, Would you consider shipping to Australia - our local supplier is pricey & has very limited info compared to your site. Any idea of shipping costs to Adelaide, South Australia? Thanks for your time, Ben

Asked by: Benjamin
Hey, Ben. Unfortunately, Prima is not currently set up for international shipments. It is a service we hope to offer in the future though.
