Frequently Asked Questions (FAQ)

How does the C40 MK4’s grind quality compare to electric grinders?

The C40 MK4 stands tall against electric grinders, often surpassing them in grind consistency and quality. The precision of its burrs and the manual control you have over the grind size allows for a more uniform grind, which is crucial for a balanced extraction and a superior cup of coffee.

  • Portable and not reliant on electricity, making it perfect for travel or outdoor brewing.

Can the C40 MK4 handle lighter roasts which tend to be harder?

Lighter roasts present a challenge for many grinders due to their dense and hard nature. However, the C40 MK4 is more than capable of handling them with its robust construction and sharp, high-nitrogen martensitic steel burrs. These burrs are specifically designed to tackle all types of coffee beans, ensuring that even the hardest light roasts are ground to your desired consistency without extra strain on your part.

What’s the best way to find the right grind setting for my brewing method?

Finding the right grind setting is key to brewing the perfect cup of coffee. Start by consulting the grind size chart included with your C40 MK4. From there, it’s all about trial and error. Begin with the recommended setting for your brewing method and adjust one click at a time. Pay attention to the taste of your coffee and the flow rate during brewing. If it’s too bitter, go coarser; if it’s too sour, go finer. Keep a record of your adjustments to replicate that perfect brew every time.

  • Consult the included grind size chart as a starting point.
  • Adjust in small increments to fine-tune your grind.
  • Use taste as your guide to dial in the perfect setting.

If you choose to use your grinder for spices, be prepared to thoroughly clean it afterward to maintain the pure taste of your coffee.

  • Brush out the grinder after each use to remove residual grinds.
  • Perform a thorough cleaning every few weeks, or as needed.
  • Regular maintenance ensures consistent grind quality and longevity.

In conclusion, the C40 MK4 Hand Grinder is a testament to the beauty of precision engineering and thoughtful design.
