Know before you buy
Yes, this grinder is optimized for espresso. Its 54mm flat burrs and stepless adjustment system are engineered to provide the fine-tuned precision required for dialing in high-quality espresso shots.
Unlike grinders with fixed notches, a stepless system allows for infinite, microscopic adjustments to your grind size. This gives you total control over your extraction, making it much easier to fine-tune your grind to match the specific roast and age of your coffee beans.
The i-STEEL is designed with enhanced noise reduction features, making it significantly quieter than many other professional-grade home grinders. While no electric grinder is silent, it is engineered to minimize harsh grinding sounds for a more pleasant morning experience.
Yes, the unit is designed for straightforward maintenance. The professional-grade grinding chamber is accessible, allowing you to clean out residual grounds easily to ensure your next cup remains fresh and free of stale coffee oils.
The hopper holds 250 grams (8.82 ounces) of coffee beans. While it is designed to hold a full hopper, many home baristas use it for single-dosing by weighing out their beans before grinding, thanks to the efficient grinding chamber design.
The i-STEEL is built to last, featuring a robust Inox stainless steel body and a grinding chamber constructed from cast aluminum and brass. These high-quality materials provide excellent stability and longevity for consistent daily use.
