Carbon Dioxide (CO2) has many purposes in your brewhouse other than carbonating your beer. It can be used to purge your carboys, bottles or kegs of flavor stealing oxygen as CO2 weighs more than oxygen. Also CO2 can be used to transfer beer from one vessel to another without the worry of adding oxygen to your finished beer. In this post I show you how I have taken a few extra bits I had laying around to build a CO2 powered racking cane:

Assembly

Instructions
|
|
1.
Cut 1” off of the long, thin stem of your Carboy Cap.
2.
Cut the rounded tip off of the center Carboy Cap Stem.Your objective is to make the stem flat and
not rounded.
3.
Insert the ¼” Barbed Inlet side of your manifold into the long, thin
stem of the Carboy Cap.
4.
Attach Beverage Tubing to the curved end of your Stainless Racking
Tube.
5.
Insert Barbed Swivel Nut into the loose end of your Beverage Tubing.
6.
Insert Stainless Racking Tube into the Carboy Cap center stem.Be sure to insert the Racking Tube so that
curved top is on the top of the Carboy Cap.
7.
If transferring to a Keg attach your Liquid Disconnect to the Barbed
Swivel Nut.
If transferring to another
Carboy leave the Swivel Nut open.

1.Sanitize your racking cane assembly to
prevent any contamination.
2. Connect your MFL gas line from your regulator to flared side of your CO2 Transfer Assembly attached to your Carboy Cap. Use the Swivel Nut Gasket in between to prevent leaks.

Carboy to Carboy
transfer:
A.
Insert your CO2 Racking Cane into the empty carboy.
B. Disconnect the liquid disconnect fitting.
C. Set your
regulator to 2 PSI and allow the gas to slowly fill the carboy.
D. Crack open one
side of the carboy hood allowing the gas to escape. Do this for 5 seconds.
E. Turn off gas and
place your racking cane assembly onto the carboy containing your beverage.
F. Place the liquid
line into bottom of the carboy
G. Open the gas and
allow the CO2 to push your beer through the racking cane into your empty
carboy.

Carboy to Keg
transfer:
A. Insert your CO2 Racking Cane into
the empty carboy.
Be sure to have the
Liquid Disconnect attached.
B. Purge your keg with CO2 prior to racking your beer.
C. Set your Regulator
to 2 PSI.
D. Open the gas and
allow the CO2 to push your beer through the racking cane into your empty keg.
E.After the beer has been transferred be sure
to shut off your CO2.

NOTE: Carboys are
not meant to hold pressure so
do not over pressurize.
