Choosing the Right Fridge

1.1 Size and Capacity

When it comes to choosing the right fridge for your DIY kegerator project, size does matter. You’ll need to consider how many kegs you want to dispense at once and how much space you have available. Remember, you’ll need to make room not only for the kegs but also for the CO2 tank, tubing, and any additional accessories you may want to add. So, before you rush out to buy the biggest fridge you can find, make sure you measure your space and plan accordingly.

1.2 Temperature Control

Beer tastes best when it’s served at the right temperature, so you’ll want a fridge that allows you to control the temperature. Look for a fridge with a digital thermostat that allows you to set and maintain the desired temperature. This way, you can always keep your beer at the perfect serving temperature, whether you prefer a crisp lager or a rich stout.

1.3 Door Configuration

Believe it or not, the door configuration of your fridge can make a difference when it comes to kegerator conversion. Ideally, you’ll want a fridge with a top-mounted freezer or no freezer at all. The reason? Well, the top-mounted freezer allows for more usable space inside the fridge, making it easier to fit your kegs and other kegerator components. Plus, without a freezer, you won’t have to worry about defrosting or dealing with icy beer lines. So, when you’re scouting for the perfect fridge, keep an eye out for the right door configuration.

Preparing the Fridge for Conversion

2.1 Cleaning and Sanitizing

Before you start turning your grandma’s old fridge into a beer dispenser, it’s crucial to give it a good cleaning and sanitizing. You don’t want any remnants of last Thanksgiving’s turkey ruining the taste of your perfectly crafted homebrew. Start by emptying the fridge and removing any shelves or drawers. Give them a good scrub with warm, soapy water, and don’t forget to sanitize them using a food-safe sanitizer. As for the interior of the fridge, wipe it down with a mixture of water and vinegar to eliminate any lingering odors and bacteria.

2.2 Removing Shelves and Drawers

To make room for your kegs, you’ll need to remove any unnecessary shelves and drawers from the fridge. Remember, you want to maximize the interior space to accommodate the height of your kegs and the draft system components. So grab your toolbox and unscrew those shelves and drawers, but keep them safely stored away in case you ever decide to convert your kegerator back into a regular fridge.

2.3 Sealing and Insulating

Now that your fridge is spick and span, it’s time to seal and insulate it. This step is essential to maintain the temperature inside the kegerator and prevent any unwanted air leaks. You can use weatherstripping or silicone caulk to seal any gaps or openings in the fridge. Pay special attention to the door seal, as a tight seal is crucial for temperature control. To insulate the walls of the fridge, you can use foam board insulation or even old beer koozies. Get creative and make sure your kegerator is as airtight as possible.

Installing the Draft System

3.1 Tap Tower Installation

The tap tower will be the showstopper of your kegerator, so you want to make sure it’s installed properly. Start by measuring and marking the location where you want the tap tower to go. Use a hole saw or a jigsaw to create a hole in the top of the fridge. Gently feed the beer line and CO2 tubing through the hole, making sure they are long enough to connect to the kegs. Finally, secure the tap tower in place using the included mounting hardware, and you’ll be one step closer to pouring your own pints of golden goodness.

3.2 Faucet and Shank Assembly

Now that you have your tap tower installed, it’s time to assemble the faucet and shank. Start by attaching the faucet to the shank using the appropriate hardware. Then, carefully insert the shank through the pre-drilled hole in the fridge door or wall, making sure the faucet is facing outward. On the inside of the fridge, attach a beer nut and a tailpiece to the shank, securing them tightly. This will ensure a proper seal and prevent any leaks when you start dispensing that liquid gold.

3.3 Beer Line and CO2 Tubing

With the tap tower and faucet assembly in place, it’s time to connect the beer line and CO2 tubing. Start by cutting the beer line to the desired length, keeping in mind the distance between the kegs and the tap tower. Attach one end of the beer line to the tailpiece on the shank, using a hose clamp to secure it tightly. On the other end of the beer line, attach a quick-disconnect fitting, which will connect to the coupler on the keg. Repeat this process for each beer line you’re using. As for the CO2 tubing, connect it from the CO2 tank to the regulator, and then from the regulator to the quick-disconnect fitting on the keg coupler. Make sure all the connections are secure and leak-free, and you’ll be ready to start pouring your favorite brews.

CO2 Setup and Regulation

4.1 CO2 Tank Selection

When it comes to selecting the right CO2 tank for your kegerator, you have a few options. The most common sizes are 5-pound and 10-pound tanks, but you can also find smaller or larger ones depending on your needs. Consider the size of your kegerator and how often you plan on using it when choosing the tank size. Remember, a larger tank will require less frequent refills, but it will also take up more space in your fridge. Don’t forget to also check the hydrostatic test date on the tank to ensure it’s safe and up to date.

4.2 Regulator Installation

To control the flow and pressure of CO2 into your kegs, you’ll need a gas regulator. Start by attaching the regulator to the CO2 tank, making sure it’s tightly secured. Then, connect one end of the CO2 tubing to the output port on the regulator, and the other end to the quick-disconnect fitting on the keg coupler. The regulator should have a pressure adjustment knob that allows you to fine-tune the pressure according to the type of beer you’re dispensing. Experiment with different pressures until you find the sweet spot that gives you the perfect pour.

4.3 Pressure Adjustment

Finding the right pressure for your beer is crucial to achieving the perfect pour. Different beer styles require different pressures, so it’s important to do a bit of research and experimentation. Generally, a pressure of around 10-12 psi is a good starting point for most beers. However, if you’re pouring a beer with higher carbonation, like a wheat beer, you may need to increase the pressure. On the other hand, if you’re pouring a beer with lower carbonation, like a stout, you may need to decrease the pressure. Keep tweaking the pressure until you achieve that ideal head of foam that makes your taste buds dance with joy.

Kegging and Connecting the Beer

5.1 Selecting and Preparing Kegs

Now that your kegerator is all setup and ready to go, it’s time to choose the perfect kegs for your brews. You can either purchase new kegs or repurpose old ones. Just make sure they are in good condition and free of any residual flavors or contaminants. Before using the kegs, you’ll need to clean and sanitize them thoroughly. Use a keg cleaning solution, followed by a sanitizer, to ensure that your beer stays fresh and tasty.

5.2 Connecting the Coupler

To tap into the wonderful world of beer, you’ll need to connect the coupler to the keg. Start by lifting the coupler handle and aligning the coupler with the keg’s valve. Gently press down on the coupler, making sure it’s securely in place. Once the coupler is attached, twist it clockwise to lock it into position. This will puncture the keg’s seal and allow the beer to flow. Give it a little tug to make sure it’s properly connected, and you’re ready to start pouring that liquid gold.

5.3 Beer Line Balancing

To achieve the perfect pour, you’ll need to balance the length and diameter of your beer line. A balanced beer line ensures that the beer flows smoothly from the keg to your glass, without excessive foam or a slow pour. Factors such as temperature, carbonation level, and line length can affect the balance. If you’re experiencing excessive foam, try increasing the line length or decreasing the pressure. If the pour is too slow, you may need to decrease the line length or increase the pressure. It may take some trial and error to find the right balance, but once you do, you’ll be pouring pints like a pro.
