Know before you buy
Yes, the 58.5mm diameter is specifically engineered to provide a precise fit for standard 58mm portafilter baskets, ensuring even distribution across the entire surface.
The leveler features a click-and-lock system that allows you to calibrate the depth to the millimeter. Once you find your preferred setting, it locks securely into place to ensure every shot is tamped at the exact same depth.
The Jack acts as a 2-in-1 tool that both distributes and tamps your coffee grounds. By spinning the device on your portafilter, it grooms the grounds and compresses them, effectively removing the need for a traditional manual tamper.
No, the wood-finish options are crafted from painted aluminum. They provide the aesthetic look of wood while maintaining the durability and weight of a metal tool.
Channeling often occurs due to uneven density in the coffee puck. By using the Jack to create a perfectly level and consistent bed of grounds, you eliminate the weak spots where water would otherwise bypass the coffee, resulting in a more uniform extraction.
Not at all. The locking mechanism is designed for quick adjustments, allowing you to easily unlock, recalibrate, and re-lock the depth whenever you switch to a different coffee bean or dose size.
