Tap a Draught Keg Inside Your Fridge





Introduction: Tap a Draught Keg Inside Your Fridge

Several years ago, 5 liter kegs hit the market.  Soon after, manufacturers developed mini fridge systems which keep the keg cold and provide a tap for convenient dispensing. Initially, the price for these appliances was prohibitive, and the system required the use of ample counter space as well as constant power to maintain the beer at a proper temperature.

The goal for this project was to have draft beer at home but without the typical trappings of a kegerator system (dedicated fridge, CO2 tanks, and electrical expense) or a dedicated appliance type of dispenser system (counter space & electrical expense).

Although the DraughtKegs are a great solution, the included dispenser requires that the keg be placed towards the front of the fridge so that you and your glass can reach the plastic spigot. This instructable provides details of how to attach a standard beer tap to your mini keg for added convenience and enhance the draft beer experience without a dedicated kegerator.

Another advantage of this setup is that the rig it is not affixed to the refrigerator and can be made into a mobile draught keg. Check my next Instructable called 'Make Your Draught Keg Mobile' to do just that:

Step 1: Supplies Needed

For the basic setup you will need the following items:
Mini Keg
Mini Keg's included dispenser
Standard refrigerator faucet (details of the tap pictured below: polished brass faucet with a 1/4" shank that measures 4 1/8" long. Includes barbed 1/4" nipple and black handle.)
About 2 feet of Micro Matic tubing 1/4 ID x 1/2 OD (internal & outer diameter)

Step 2: Remove Rubber Bumper

To make room for the thick supply line, we must first remove the rubber bumper located on the base of the mini keg's provided dispenser. The rubber piece can be separated from the base by simply pulling the two apart.

Step 3: Seperate the Included Spigot

The spigot provided with the mini keg is actually made up of two pieces. The long stem needs to be pulled apart from the small elbow piece (see pictures).

One important item to note is the small hole on the bottom of the elbow piece (circled on the second picture). It is very important that when we connect our supply hose to this elbow piece that we cover up this hole with the hose.  Otherwise, beer will flow freely from this hole and make a big mess.

Step 4: Fashion Hose to Elbow Dispenser

The elbow piece removed in step 3 must now be attached to the supply line. Make sure to push the entire elbow's barbed nipple into the hose as shown below. The hose should fit very tightly over the nipple and as described in step 3, should cover the small hole which is on the underside of the elbow.

User caution - It is critical that you have a tight connection here otherwise you will have a mess on your hands.

Step 5: Connect Hose to Keg

Per the instructions included with the mini keg, connect the dispenser base to the keg and then connect the hose inside the base. Keep the dispenser tap in the off position as pictured below until the faucet has been attached to the other end of the hose - which is the next step.

Step 6: Connect Refrigerator Faucet and Switch On!

Finally, connect the other end of the hose to the faucets 1/4" barbed nipple and assemble the rest of the taps components. Again, I caution that the connection between the hose and the barbed nipple needs to be very tight.

At this point I need to add a small disclaimer: Before flipping the mini keg dispenser to the 'On' position, make sure that the faucet tap is opened. If the faucet is not open when the keg starts dispensing back pressure can create at the top of the keg and beer will begin seep from the top and can empty your keg if not stopped. So, as indicated, open the faucet before turning on the mini keg dispenser.

For my implementation, I crafted a small stand which would hold the faucet in place while in the fridge - that's the next step...

Step 7: Building a Simple Faucet Stand

Using materials that I had on-hand, I put together a simple stand which sits in the fridge and holds the faucet. Basically, its two pieces of wood held together by corner brackets on each side with a notch cut out from the top piece. As you can see the faucet slips into the notch and the faucet's bolt is used to secure the faucet in place.

Something much more elaborate could have been put together but this works as a simple stand.

Once complete, slip the entire contraction into your fridge and enjoy a cold draft beer from your mini kegerator!

As mentioned earlier, another advantage of this setup is that the rig it is not affixed to the refrigerator and can be made into a mobile draught keg. Check my next Instructable called 'Make Your Draught Keg Mobile ' to do just that:

Could i have the keg in a mini fridge below the counter with the hose coming out of the fridge through a hole and going up to a tap on the counter. Or would there not be enough gas pressure to get the beer up to the tap.



Where did you buy the Faucet?

got a few ;) kegs of desperados followed instructions but my spigot is totally diferent. :( please help me


How easy is it to chnage a keg? I love this idea and would like to use it this summer. I plan to shove 2-4 kegs in the fridge and another in the portable cooler. But its not clear to me, as I am limited to bottle beer at the time of this writing, how easy it would be to change kegs in a party?

It would be very easy you just remove the spigot connected to the tube and everything else then connect it to the new keg.

nice job i wonder if a mini fridge could be used and drilling in the door could i seal that up and make it so i have it on the counter

Can this be done with the other mini kegs? The Heineken look like the same design but the Miller light and Coors light look a bit different.

Hello mate, I've found this CO2 tap for those other type of kegs you can reuse them and buy replacement bungs etc, have a look here: http://www.leylandhomebrew.com/item2600.htm

Simple and cheap! I really like it.

I wonder if buying these Mini Keg's is any cheaper than just buying bottle beer though. :/

Unfortunately it's not. New Castle by the bottle is always cheaper than the mini keg - at least in my area!

But New Catle in the mini keg is much much better. Their clear bottles ruin the beer.

if you really want to go the extra step. mount it right on the fridge door or rout it through the water line so instead of water coming out the freezer, beer comes out

Craig3 - I purchased my tap at a local brewery supply store in Cincinnati (listermann.com/). You can look in your area or check out eBay. Best of luck!

That's very nice. That mucky-stuff needs to be served cold... and these days it's brewed in Gatehead


a work of brilliance! when some extra funds roll around I'll be sure to add this!
