Compak i3 Pro Mini: espresso dosing with a lower profile
The Compak i3 Pro Mini brings a hopper-fed espresso workflow to counters where height matters. Its 58mm flat steel burrs and stepless adjustment let you dial in a house espresso or a dedicated second coffee, while the LCD keypad keeps single and double dose settings close at hand.
Choose the Mini for a smaller hopper and a lower overall profile. It shares the full-size i3 Pro’s 190 × 315 mm counter footprint; the difference is overhead space and bean capacity, rather than a narrower base.
Timed doses, with a scale for calibration
Program a single or double grinding time, or use continuous grinding when you want manual control. The grinder measures time, so you still weigh the grounds while setting your recipe. Changing beans, grind size or hopper level can change the number of grams delivered by the same timer setting.
A practical second-coffee station
The 400g hopper suits a smaller espresso station or a dedicated decaf position without the height of the 700g i3 Pro hopper. If your plan involves switching beans for every shot, compare the PK100 Single Dose, whose intake and workflow are designed around pre-weighed portions.

Frequently asked questions
Is the i3 Pro Mini a touchscreen grinder?
It uses an LCD display with a capacitive keypad. Its programmable single and double dose controls are different from the 2.8-inch touchscreen on the E6 and E8.
Will it fit under a 17-inch cabinet?
Its published height is about 16.54 inches, but that does not include the working clearance you need to lift the lid and refill the hopper. Measure the available space with that task in mind.
Does it weigh each espresso dose?
No. It controls grinding time. Use a scale to check the delivered dose and recalibrate the timer after dialing in or changing coffee.
What is different about the full-size i3 Pro?
The main buying differences are the 700g hopper and 515mm overall height of the full-size version. Both models use 58mm flat burrs and have the same published width and depth.
Can I use it as a decaf grinder?
A dedicated decaf hopper is a practical application. Clean and purge according to your workflow if changing between regular and decaf beans; an espresso grinder should not be assumed to eliminate all carryover.
Is it suitable for a busy café’s only grinder?
Assess the busiest run of drinks, not only the daily total. For repeated peak-service grinding, compare the larger E6, E8 and Bolt platforms and discuss your expected workflow before choosing.
