Building a kegerator
Tired of cleaning out your bottles? Maybe it is time to start kegging your beer! Like anything else there are certain advantages and disadvantages to almost every process that can be done more than one way. Let’s face it, our goal as homebrewers is to have a full glass of the highest quality homebrew you have the ability to make. How it gets in your glass can be a tale of two methods.
We all know the painstaking procedures (labor of love- right?) that comes with bottling your beer. If this process could be avoided, most would say, sure- sign me up! The alternative to the process is to keg your beer. The major disadvantage that may scare some away is the initial investment. Now, cold keg beer can be had and served for less than a $100 initial investment. Here is how.
The first thing you need is a refrigerant. Within one week many quality options can be found on craigslist for $25-50. When choosing one, think of the future: is this just going to be strictly to chill one keg and space is a concern, or will this be the base of a constantly upgraded system? If you are planning on starting simple but know you will be slowly collecting parts to add for future upgrades, then your choices can range from a small dorm fridge, to an upright refrigerator, to a chest freezer.
The next thing you will need is a keg of beer and a tap. A used and refurbished cornelius keg can be purchased on the internet from several sources for between $30-40. Without getting into many details (previous blog), keg your beer, and put it in the fridge. Now to dispense. A picnic tap can be purchased for approximately $9, and will hook up directly to the outpost of your keg. To pressurize and serve, a portable CO2 canister ($20) can be connected to the in post and voila! You are ready to serve cold beer. If you snag the bargains the parts add up to about $95.
The next upgrade would be to add a gas source. CO2 tanks can be purchased for about $80 for a 5lb tank to $150 for a 20lb tank. A 5lb tank should last approximately 10 kegs and will cost an average of $15 to fill /exchange. All that needs to be done is hook a line up to the gas regulator, (approx $60) and connect a quick disconnect to the other end. The QD will then be hooked up to the in post of your keg (ball lock or pin lock). Now you can carbonate, condition and serve under constant CO2 pressure.
That is the inexpensive version. Now lets say you want to upgrade this party to serve out of a faucet. Simple. All you need to do is select a placement for your faucet’s shank to be located, (usually the door of the fridge- but depending on model and configuration can be any accessible location from inside, as long as coolant lines are not present). When selecting faucet location, think of the future and what upgrades to additional faucets you may add on later, so a symmetrical look can always be maintained.
Now all you need to do is install the shank. You will of course need a shank, a faucet to connect to the shank, a tailpiece to connect your serving bevline to, and a quick disconnect to match your kegs out post. Start by locating your faucet shank placement on the fridge (again making sure no coolant lines are there- never any on a door). Next drill a 1/8″ pilot hole all the way through, making sure the drill bit entry is completely level both up and down and side to side, this will insure the exit hole is an exact match to the entry. Now widen the entry hole with either a 7/8″ hole saw, or the preferred 7/8″ stepped drill bit. Now widen the exit hole the same way and remove any insulation that is between the two. Assemble your faucet to your shank, (if you have a vanity collar for the shank do not forget to slide this on), and push through the hole from the front side. Secure the shank in place with the shank supplied back nut, and attach the tailpiece. Connect the bevline (usually 3/16″) to the tailpiece, and the other end to the outpost of your corny keg. All gas and bevline connections should be secured with hose clamps, (oetiker or ear styles are preferable, worm styles will work- just avoid overtightening). Screw the tap handle on the faucet and crank the gas up to 10psi and pour your beer! [IMG]http://i218.photobucket.com/albums/cc314/thirsty_02/FRP.jpg[/IMG]
Want multiple lines? Easy enough. Repeat the above procedure for each faucet, the only thing you need to add is more gas lines. This can be done by connecting your main gas line to a distributor manifold. These can be purchased with multiple splits with their own shutoff and check valves, and each of those lines can be split as well. The distributor can be mounted to the fridge interior wall. Now just connect a gas line to each gas barb that you need to attach a keg to. Easy as that!
A few upgrades that you may want to consider:
-Drip collection trays- mount below the faucet(s)
-Custom platform for fridge interior to keep multiple kegs on single level
-Temp controller (Johnson or Ranco type) for exact kegerator temp (necessary on freezer type)
-CO2 bulkhead- allows CO2 line pass through keeping tank on outside, allowing more interior fridge space (maybe another keg?)
-Gas and liquid in line QD’s to toggle between a corny keg and sanke keg attachment, this will allow you to also pour a commercial keg off the same system
-Moose antlers (again optional)
So if bottling is getting too tenuous and you do not want to wait 2 months to drink your new favorite brew, serving from a keg can be done for less overhead than many think is possible. If you are even thinking if it is worth it or not- just my humble opinion, go for it! You will not be disappointed.
Prost!
