HOMEBREW ON TAP --REAL BEER

1. That you have had a beer fermenting and it has been left some extra time to clear. If you have the coldspace, you may have let the fermenter clear there.
   
2. It is important to note that if you do an SG test that you clean the tap immediately, as bacteria will build up very quickly on beer droplets that are left in the tap.
   
3. That you have a keg that has been properly cleaned with YOUNGA`S FERMENTER KEG AND LINE CLEANER or a suitable alternative.
   
4. That you have cleaned the transfer tube. This tube is usually a metre long and 12m.m. in diameter and is used to transfer beer from fermenter to keg.
   
5. That you have removed the airlock.
   
   Clean your hands, check the tap is clean, put the tube on the tap and down into the open keg with the tube deep in the keg, usually on the bottom. Open tap and fill keg. Do not overfill your keg, the weld mark is about right, no higher than 30m.m. below your lid opening.
   
   Replace the lid, connect up gas at a fair pressure this is usually around 260k.p.a. and release air out 3 secs.
   through the air relief valve. This procedure pushes out regular air that could oxidise or contaminate the beer.

GASSING YOUR KEG
In our experience an 18 litre keg takes the best part of 48hrs. to get properly cold. For this reason our recommended gassing time is 48hrs. As beer chills it readily takes in the gas at pressure, above it. The other side of this is cold beer poured into a warm glass. It foams up excessively, it is releasing gas as it warms.

Cold beer dispensed through a hot beer tap will also foam excessively. You can gas the keg hot, although we are yet to see any advantage of this procedure, as the beer will take 2 days to get cold anyway. In fact there are some real disadvantages as beer stored hot without any preservatives, can go off unless the brewing procedure was spot on. Storing your made up beer in the fridge has an advantage in that the beer mellows out or "lagers".

The best description I ever heard of lagering was that harsh alcohol was turned into smooth alcohol. We will assume the keg has been filled and purged of regular air that could stale it. Put it into the fridge and connect up the gas disconnect. Set the regulator to 260 k.p.a. pressure. The gas bottle should be left on to provide the reg. with the gas it needs to do the job.

This will take 48 hrs. and then the beer will be gassed up and cold. For kegs bigger than 18 litre you will need to gas for longer periods. A 45 litre for example will take 72 hrs. When gassing up stouts you will probably not want it as gassy and so your gassing procedure should change to something like 180k.p.a. for 48hrs for an 18 litre keg. Vary k.p.a. to suit. The beer continues to improve as it lagers. The regulator gets it`s name from the fact that it regulates gas pressure. Gassing procedures involving turning the gas bottle on and off are only for people that are unsure of their keg systems ability to hold pressure.

SETTING PRESSURE FOR DRINKING
When the gassing time is up, it is important to release the pressure back to a pressure that you can pour with. If we tried to pour at 260k.p.a. the beer would be everywhere. If we were to leave the beer at 260k.p.a. the beer would be over-gassed and come out as foam. When the set time is up, turn off the gas bottle, wind back the regulator at the same time releasing gas through the air relief valve until the gauge showing the line pressure has dropped to around 40k.p.a. You may now turn the gas bottle back on.

Connect the pluto gun or beer tap disconnect up to the keg and pour beer. If the beer is pouring too fast or too slow, reduce or increase the pressure by adjusting the regulator. Once a suitable pouring pressure has been established, the gas may be turned off. I feel this is a good procedure to follow, as any loss of pressure from the system will easily be noticed when you go to pour the next beer. If the pressure has dropped and you are sure it is not just due to the fact that the gas space has increased as beers were poured from the keg, you most likely have a problem somewhere that will need to be rectified. If you are pouring lots of beer, leave the gas bottle on and turn it off at the end of the session.

As you finish a session, always leave the beer with at least pouring pressure on it, otherwise it is like a bottle of softdrink with the lid left off, it will go flat. The speed of the pour, controlled by the pressure has a bearing on the head, the other factor is the level of gas in the beer. Pouring pressure is a balancing act between too much or too little head. You get better!!

CLEANING YOUR KEG
After you have enjoyed the contents of your keg, disconnect the gas and liquid lines. Do not remove the keg from the fridge or open the keg, unless you intend to clean it straight away. When you are ready to clean the keg, release all the pressure from it and open it up. Fill the keg with 2-3 litres of town water, shake, tip out and repeat the rinse with another 2-3 litres. This should ensure any residue is washed out of keg.

Once this has been done add 50ml. of Younga`s cleaner and 5 litres of town water, seal and shake keg. Connect gas and liquid lines. Pump the cleaner through the lines until all the beer is out of the line and your tap or pluto gun is dispensing the cleaner

Leave the cleaner in your system for 30mins. Pump the 5 litres through your tap or gun into a bucket. The cleaner is corrosive so don`t splash the fridge. It is not a good idea to keep your bottle of cleaner on the top of your fridge either, for the same reason. There will be some cleaner in your lines and this needs to be rinsed out. Disconnect your lines, release pressure and open keg. Rinse out at least twice and then fill with 5 litres of clean water. Rinse the keg lid as well. Seal up the keg.

Connect up your gas and liquid lines and pump the 5 litres of water out through your tap or gun. This has rinsed your beer line free of cleaner. Younga`s cleaner has a free rinsing agent to help rinse away the active ingredient. Do a 3 sec. purge to clear out any regular air and now your keg may be stored until you have clear beer to fill it with. It is clean and ready to use. Enjoy your system. Cheers,
Younga.
