Built to last
Food-safe first. Barista-grade always.
Every part that touches your coffee is SS304 stainless steel, the food-grade standard of professional kitchens. It stands up to steam, water and daily rinsing without rusting, and it adds nothing to your shot but heat stability.
Each tool is weighted just right: a solid, balanced heft in the hand that makes every dose, tamp and pull feel like the real barista ritual.
Why bottomless?
A spouted portafilter hides the extraction. An open basket shows it to you, so every shot teaches you something.
02
Learn from every pull
Spraying or uneven flow points you back to dose, grind, distribution or tamp, so you know what to change.
03
Fix it next time
The WDT tool, tamper and puck screen in the box are the fixes for the most common problems.
