What other manufacturer knows more about sating the throngs of coffee addicts lined up outside your cafe in the bleary morning hours? Rancilio moves beyond high-end commercial espresso makers with their professional line of grinders so that you can control everything about the shots of liquid energy your barista's craft for your customers.

The smallest of the MD line, the MD 40 is a Semi-Automatic grinder constructed of die-cut aluminum wrapped in polished steel and topped with a super-large, blue tinted and UV protected bean hopper designed to hold over a pound of roasted espresso beans. Appointed with tempered steel grinding plates that shred through beans, the MD 40 can produce over 7 pounds of fresh espresso in the span of an hour. Rounding out its features, the integrated doser makes it easy for the busy barista to tap out just the right amount of grounds into the waiting portafilter or press. Simply put, this grinder is a must-have for any cafe looking for quality, consistency and productivity from their grinder.

Features and Functionality

  • Commercial Capacity: The powerful motor and grinder unit of this machine can turn beans into espresso in two seconds flat. Designed to deliver over 7 pounds of ground coffee in an hour, there isn't a coffee shop or cafe around able to provide demand that exceeds the Rancilio's ability to deliver.
  • Steel Burr Grinder: The heavy duty 55mm burr grinding plates are made of tempered steel and operate at a super low RPM (rotations per minute) to prevent unnecessary heat build-up and transfer to your coffee beans. The grinder's motor is housed in thermal protection to prevent overheating.
  • Coffee Dosing System: The MD 40's dosing system adjusts from 5 to 10 grams per dose.
  • Semi-Automatic: You'll manually adjust the machine to fill the dosing chamber, which gives you a tad more control over output.
  • Great Bean Hopper: The Rancilio hopper keeps 1 pound of coffee beans well sealed so they remain fresh and ready to grind. The blue tint prevents UV rays from damaging the beans in the hopper.
  • Built-In Tamper - MD 40 has a built in (and removable) tamper that's adjustable between the 53mm and 56mm portafilter sizes
  • Doser - Easy portioned coffee with a twist of a lever? The built-in doser on this machine does just that
  • Price - If you're not setting up your cafe or office to handle this quantity of coffee, you might want to consider a machine that matches your usage better
  • Semi-Automatic - The MD 40 is Semi-Automatic, so you'll have to manually turn the machine on or off to fill the dosing chamber

I have a Rancilio Rocky Coffee , which grinds for Turkish coffee as well, my question is what's more in MD 40?
Greg G on Feb 13, 2015
Best Answer: The Rocky will be great for a home machine, but you would use the MD 40 in a small cafe or office situation, where it will be grinding for a longer period of time or more frequently. The MD 40 also has slightly larger burrs (55mm) so it will grind just a little faster, and only comes in the doser version, with a tamper built into the side of the doser, allowing you to tamp upwards slightly right at the machine. This is intended for a heavier use situation that just at home.

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.
