Well shake it up baby, now, Twist and shout! The manual Macap M4 Stepless Doser Grinder will work it on out. With the Macap M4 grinder's stepless adjustment, you'll have total control over your grind from coarse French press to fine espresso. With just a twist of the knob, it will twist so fine. Made in Venice Italy with years of Italian espresso experience, the M4 grinder is a smooth operator.

Features and Functionality

  • Good Capacity - The sturdy clear plastic bean hopper with finger guard holds holds up to 1.1 pounds of fresh whole beans and features an integrated trap door that allows for easy changing of beans without emptying.
  • Consistent Grind - The stable 58mm stainless steel burr grinders are flat (rather than conical) and remove for easy cleaning. Designed to operate at a low RPM (rotations per minute) so that minimal heat builds up and is transferred to your beans.
  • Stepless Adjustment - The M4 features a worm-driven stepless adjustment. Simply twist and pull the adjustment pin to advance the beans from the hopper into the grinder. You can adjust as the grinder is working.
  • Doser - The adjustable doser gives you control of churning out between 5 and 9 grams per pull, and features a shot counter on the side of the unit.
  • Stepless Control - Revel in precise control over the consistency of your grind.
  • Large Hopper - Super large hopper holds 1.3 pounds of beans.
  • Doser Control - The precise and manual operation you get from the doser is a nice touch if you want complete control over how much is being loaded into your portafilter.
  • No Reference Marks - Because there is no end to the turns on a stepless knob, there are no markers to help you recall your grind settings from one to another.

Hi, two questions:
1) Is there any reason to consider the Rancilio MD40 Commercial Grinder over the Rancilio Rocky? This would be for home use-- grinding enough for 3-6 cups espresso per day (Via Venzia machine).
2) With moderate daily home use, can I justify a splurge on the Macap M4 or should I just be happy with the lower priced Rocky since all of them will probably break after a few years use?? Help please! Thanks for all videos. So helpful.

Best Answer: The MD40 is a beautiful machine but I don't see why it should be the choice for home use, unless you just like it more, over $500 more. True it's semi automatic but it's not hard to dose. I have two with dosers (one up at the cabin) and first bought one 4 years ago and haven't had the slightest problem with it. It gets daily use (3-8 shots/day) and produces a constant reliable grind.

Hello everyone.
I am still looking for a smaller sized espresso grinder for a coffee shop. Will Macap M4 stepless doser work to produce 200 cups a day?
Thank you,
San Francisco

great grinderReview by Dennis
I had a Rancilio Rocky for about 10 years with a Rancilio sivlia machice. And a gaggia machice for 10 years before that.I alway's got nice shots from both of those machices It was time to step it up so i bought a rocket giotto v 2 and macap m4 grinder. This combo works great. The Macap is a lot quieter than the Rocky,It also did take about a week or so to find the right setting.but once you find your setting it produces some great shots. I love the stepless doser
You can really dial in the right grind,i couldn't do that with the rocky.
So my shots are much for grinds left in the chute i just use a brush on the center post and hit the lever 2 or 3 times and all the grinds come right out.great grinder cleans up very nice. (Posted on 7/23/2013)
I am set with my Macap MC4Review by Tracy
I replaced my Rancilio Rocky with the Macap MC4. The Rocky was a nice starting point, but I was ready to take it to the next level. It did take about a week or so to find the right setting, but I rarely have to adjust it any more. The one complaint that I have (as well as other people), is the issue of the grounds sticking in the chute. It leads to a lot of waste and it makes a mess when the grounds finally fall out AFTER you already cleaned the area. Now I use a chopstick to get those last grounds out and into the portafilter where they belong.Once we find your proper settings and solve the issue of the grinds sticking in the chute, it is a great machine. I am not going to change my grinder any time soon.

Still getting used to itReview by isitnews
I use the Macap MC4 doserless grinder to make two or three espresso drinks a day. It is an upgrade from a Rancilio Rocky.

I used my Rocky for over a year. It took most of that time to learn how to get consistent shots with it. Once I got to that point I figured I was ready for an upgrade. Without any personal experience of the prosumer grinders on the market I read the reviews and comments on the web and decided that the Mazzer was the ultimate but that the Macap was thought to be as good in some respects, like the quality of the grind.

I have been using the Macap for about three weeks. I am still learning. I don't have it down pat yet but after my experience with the Rocky I expect it to take a while. I like the solidness of it. The Macap is a lot quieter than the Rocky and has a reassuring feel. The grind is very nice, of course and the fine, stepless adjustment is beautiful.

On the other hand it is hard to get used to the coffee that stays in the chute. There is a lip up in there that the coffee hangs on and the chute will hold 7-8g of grinds. I had a pretty good routine with the Rocky and was able to get into fresh grinds with a 4g waste. I don't have a good system with the new machine and I expect to toss 7g with the first shot. And with that lip/shelf up there I am never sure if I am getting all fresh. On the other hand the grind is clump free. (I suspect that is the purpose of the lip.)

This grinder is quiet and produces a nice grind. On the other hand there is more waste than I like and it would be a real pain to open it up for drip or french-press grind. I am going to continue to work with it. Maybe after a year I will have it down pat.

I would recommend this to a friend who understands that the high price is for the best results, not ease of use.
