Fermenator™ G4 - Carb Stone Kit

Carb stones do present a potential contamination issue with their small pores.  That’s why we developed an optional three-piece design to allow the stone to be completely disassembled for improved sanitation.  And the stem is long enough to fully reach into the main fermenter body, so the bubbles don’t just quickly combine and lose their effectiveness.  This stone can also be used for oxygenating the wort before fermentation!
