Current batch · tested before shippingWe test every production batch before it ships and publish the results — not marketing claims, measurements.
Is this right for you yet? (honest answer)
If your beans are stale or your grinder can't grind for espresso, fix those first — nothing on this site will save the shot. But if you have decent beans and a capable grinder and your shots are still inconsistent — sour one day, bitter the next — this tool removes one of the variables causing it. That order — grinder, beans, technique, then tools — is also how the included course teaches it.
The mechanism
Watch it click at exactly 15 kg.
Inside is a calibrated spring. Press until you feel the click — identical force on every single shot. Tamping pressure stops being a variable, forever.
