A counter pressure bottle filler lets homebrewers fill bottles straight from a keg without losing carbonation — essential if you want bottled beer that’s just as fizzy as what’s on tap. Setups range from simple tap-mounted fillers to full CO2-driven bottling guns.

Buying tips
- Chill and pre-carbonate your keg before bottling — warm beer foams far more under counter pressure.
- Always purge bottles with CO2 before filling to displace oxygen and reduce oxidation.
- Tap-mounted fillers are fastest to learn; gun-style and iTap-style fillers give more control once you’ve practiced.
