Know before you buy
The CORE burrs are designed for a balanced, versatile profile suitable for both modern espresso and filter coffee. The ULTRA burrs are engineered for maximum clarity and separation, making them ideal for those who prefer light-roast, high-acidity specialty coffees.
Adjusting the RPM allows you to manipulate the particle distribution of your grind. A lower RPM generally produces fewer fines, which can increase clarity in the cup, while a higher RPM can increase body and texture, giving you more control over your extraction.
Yes, the grinder is designed specifically for single-dosing. The internal geometry and anti-static features ensure that the weight of the beans you put in is exactly what you get out, with virtually no grounds left behind in the chamber.
It is very straightforward. The 5-micron stepped adjustment dial is highly precise and repeatable, allowing you to quickly dial back to a previous setting without losing your place.
The chamber uses a magnetic clam-shell design that allows you to open, brush out, and reseal the unit in about 30 seconds. No tools are required, making it one of the easiest high-end grinders to maintain.
The Purge button is a safety and maintenance feature designed to clear any residual grounds or potential jams in the burrs. It is particularly useful if you are switching between different bean types or roast levels.
