Bevo Tech dry hopper or “hop doser” solves the problem of introducing oxygen during dry-hopping by allowing you to purge the air out of your hops before dropping them into your fermenter. The “doser” includes a 4″ butterfly valve that attaches your fermenter’s 4″ dry-hopping port.

• 4″ TC Connection on the top opening of the Fermenters
• 2 x Carbon Stones for the CO2 inlet & outlet
• 1 x Pressure Gauge
