Purge CO2 from Kegs June 01 2015

For those of you who keg your beer, it's a good idea to purge your keg with CO2 prior to racking/transferring so that no air comes into contact with the beer.

Here's a couple ways to do this if you're racking from a fermentor to a keg:

1) Simply connect the gas disconnect to your gas-in post and allow the gas to enter the keg for 7-10 seconds. CO2 is heavier than air, so it will settle to the bottom of the keg, displacing the air as you rack your beer in to the bottom of the keg. 

Here's a variant of this step: Fill your keg with Co2 prior to racking, than use a screw driver to press the pop it valve on the liquid side to drive out all the pressure via the liquid dip tube.

2) Try connecting the gas disconnect to your liquid-in post, allowing the gas to enter the keg via the dip tube. Then rack into the bottom of the keg. A word of caution here: The gas disconnect is not designed to fit on a liquid post, so it might take some effort to remove the disconnect from the post.
