These valves can be obtained fairly inexpensively or built diy style. Just place a hop bag full of your hops in the keg when transferring from primary to secondary and leave the bag in there until you drink all the beer and are cleaning the keg.
2 modified end cap will work on any american sanke keg with the valve removed.
Fermenting in a keg. In the fermentation keg consider bending or cutting the dip tube. The fermentation keg will have all the trub at the bottom that you won t want to transfer over to your serving keg. My preference here is to simply bend it so i can adjust it later on.
In the serving keg get a floating dip tube. No matter how much you try to leave the trub behind in the fermenting keg some will make it over especially if it was moved over before final gravity was reached. Advantages of fermenting in a keg the main advantage of fermenting in a keg is that you can cut out almost any chance of oxygen contamination.
You can purge the receiving kegs prior to racking by either leaving the lid unsealed and filling with co2 for a 20 30 seconds prior to racking or by filling the keg with sanitizer and pushing all the sanitizer out with co2. Connect your co2 tank to the fermenting keg with the regulator set to the same 3 5 psi you initially filled each keg with. Attach the jumper line to each beer out post on the kegs.
Vent the pressure from the serving keg to start the flow. C02 will flow out of the serving keg as it slowly fills with beer. Fermenting under pressure in a keg can be accomplished by using a spunding valve.
A spunding valve basically allows you to set up the fermentation at a certain pressure when this pressure is exceeded the valve will release co2 into the atmosphere. These valves can be obtained fairly inexpensively or built diy style. One of the most convenient features of using a keg for fermenting is that you can use co2 to transfer beer from primary to secondary.
This process is closed and does not rely on gravity or siphoning. To do this some brewers like to cut about 3 4 of an inch 2 cm off the end of the liquid dip tube to avoid picking up yeast from the bottom of the keg. The pickup tube will suck in yeast sediment at the bottom of the secondary fermenter and transfer it to your serving keg.
To eliminate this just watch the tubing and disconnect the jumper line once the beer changes from cloudy to clear. Connect your co2 tank and a cobra tap to the receiving tank and blow out the yeasty beer. Just place a hop bag full of your hops in the keg when transferring from primary to secondary and leave the bag in there until you drink all the beer and are cleaning the keg.
If you leave enough head room in the keg to allow for krausen you could theoretically use a keg and this airlock to do primary fermentation as well. Fermenting in a corny keg or a sanke keg is a great way to save time and streamline your fermentation. Many brewers using this method will cut a couple of centimetres off the dip tube of the fermenter keg.
This prevents the yeast and sediment from being sucked up when serving or transferring. 2 modified end cap will work on any american sanke keg with the valve removed. It was designed to be used with a keg w 2 sanke ferrule.
Here is the description for the keg w 2 sanke ferrule. Keg w 2 sanke ferrule 160 in stock 15 5 gallon with 2 sanke ferrule. This is simply a standard beer keg without the valve spear.
