Do you having a kegging system with beer faucet, and want to bottle kegged beer? The Nukatap Counter Pressure Bottle Filler is an easy way to fill bottles directly from your beer faucet while preserving carbonation in the bottle. The O ring sealed beer inlet nipple press fits into any beer faucet with 10.0 mm inner diameter spout/nozzle including Nukatap, Intertap, Perlick Forward Seal, and Ventmatic faucets.

For the gas inlet side, a male ball lock fitting is provided, so you can use any ball lock gas connector to attach the C02 purging gas. This gas should be at the same pressure as your kegerator dispensing gas, and should be connected to your kegerator C02 regulator. Not Included: you will need a spare gas line from your regulator kegging system with a female ball lock on it to connect your purging C02 gas.

The integrated counter pressure relief valve gives you control of the counter pressure and thus the filling speed. How fast the bottle can be filled without too much foaming depends on CO2 level, beer temperature and bottle temperature. Keep everything cold for the best results.

Fits all 16 ounce and 32 ounce ‘Grolsch’ style swing top bottles.

The compact Wort Whipper from KegLand is only 1.1″ thick, and 4.75″ wide. Although this unit says it can stir up to 5 liters, we have tested it and found it is only good for up to 2000ml of wort in a 3000ml Erlemeyer Flask. Still, it is an excellent value for $40.00.

This unit has variable speed, and it is best for yeast growth to set the speed as low as possible so the yeast is suspended without it looking like a tornado. A magnetic stir bar is included, although the pictured 3000ml Erlenmeyer Flask is not included.
