The present invention pertains to a brew head assembly comprising a gear-driven locking assembly and a sealing assembly, whereby the brew head assembly is capable of sustaining pressures up to four (4) bars. The locking assembly comprises a lever, drive rod having a gear or gear-tooth surface, drive rod clamp, lock plate having a gear-tooth surface or gear on its upper surface, lock plate or gear stopper, lid mount, and brew head bottom, all operatively linked to form the locking assembly. In a preferred embodiment, the lock plate is in the form of a sliding member or rotating disc. The gear or gear-tooth surface on the lock plate will mate or mesh with the corresponding gear or gear-tooth surface on the drive rod, such that movement of the lever translates into rotation of the drive rod and movement of the lock plate into a locked or unlocked position.
