What is included with the Comandante C40 Mk4 Black?
The package includes the C40 Mk4 Nitro Blade grinder with a black powder coating, a crank with a black-lacquered oak knob, one transparent Polymer Bean Jar, one dark glass Bean Jar with lid, a small Comandante wrist band, and a merino wool felt mat. The two jars each hold about 40 g of coffee.
How should I clean the C40 Mk4?
For routine cleaning, disassemble the grinder when needed and brush coffee dust from the burr and interior; compressed air or a blower can help reach narrow areas. For a wooden-veneer model, use a damp cotton cloth on the body and dry it promptly. Comandante says not to soak the grinder.
Is the C40 Mk4 dishwasher safe?
No. Comandante says not to wash the C40 in a dishwasher because this can damage the wooden veneer and ball-bearing cartridges over time. The company also advises against soaking it. Cleaning with a brush and, for the body, a damp cloth is the lower-risk approach described in its care guidance.
How often should I clean the C40 burrs?
Comandante says cleaning frequency depends on use: about once a week for heavy use or once a month for light use is generally sufficient. It also recommends regular cleaning of the burrs and interior to keep the grinder running smoothly, while using a clean bean jar for each dose helps keep ground coffee fresh.
What grind settings are starting points for the C40 Mk4?
Comandante lists 3–8 clicks for Ibrik, 7–13 for espresso, 14–20 for a Bialetti or stovetop pot, 18–35 for pour-over filter coffee, and 25–35 for cupping or French press. These are starting points; the company recommends adjusting to the coffee, recipe, grinder, and taste.
Are C40 Mk3 jars and Red Clix parts compatible with the Mk4?
Yes. Prima Coffee states that C40 Mk3 parts are backward compatible with the Mk4, including the glass jar and Red Clix adapter. This means an owner upgrading from a Mk3 can continue using those components with the Mk4, subject to the part being the corresponding Comandante component.
What should I do if my C40 Mk4 develops a problem?
Comandante’s FAQ says that if something goes wrong, owners should contact their local dealer or Comandante directly, and that the company will take care of the issue. The page does not state a fixed coverage duration, so confirm the applicable support or warranty terms with the seller or manufacturer for your purchase.
