vessel mill herb grinderPrecision Grinding Technology The Vessel Mill uses a clever tooth design that actually shears your material rather than just crushing it down. This gives you a much fluffier, more consistent texture which really helps with airflow and flavour. Weve found the magnetic lid is nice and secure, and the smooth threads mean you aren't struggling to open the chamber when you're ready to go. Its a very tactile, reliable bit of kit that just works every time.
