How to Build Your Own Keezer (Keg Freezer) for Your Craft Beer Business

As a craft beer business owner, having the perfect temperature for your beers is crucial. While pre-made kegerators can be expensive, building your own keezer can save you money and give you more control over the temperature and dispensing of your beer. In this article, I will provide step-by-step instructions on how to build your own keezer for your craft beer business.

Gather Materials and Tools

Before starting your project, gather all the necessary materials and tools. Here's a list of what you'll need:

Materials

• Freezer (9 cubic feet or larger)
• Temperature controller
• CO2 tank and regulator
• Kegs
• Faucets
• Shanks
• Tubing
• Hose clamps
• Drip tray
• Sanitizer
• Wood for collar (optional)

Tools

• Drill
• Hole saw
• Screwdriver
• Wrenches
• Tape measure
• Level
• Sandpaper

Construct the Keezer

Once you have all the necessary materials and tools, it's time to construct your keezer. Here's a step-by-step guide:

Step 1: Build the Collar

Building a collar is optional but highly recommended, as it creates a barrier between the freezer and the environment, preventing temperature fluctuations. Follow these steps to build a collar:

1. Measure the width and depth of your freezer.
2. Cut your wood to size (typically 2x4 or 2x6).
3. Sand the wood to ensure a smooth finish.
4. Attach the collar to the freezer using screws.

Step 2: Install the Temperature Controller

1. Mount the temperature controller to the collar or the side of the freezer.
2. Plug the freezer and the temperature controller into the power outlet.
3. Connect the temperature probe to the controller and place it inside the freezer.

Step 3: Add the Faucets

1. Drill holes in the collar or the freezer for the shanks.
2. Insert the shanks through the holes and secure them with nuts and washers.
3. Attach the faucets to the shanks using a wrench.
4. Connect the tubing to the back of the faucets and secure them with hose clamps.

Step 4: Attach the CO2 Tank and Regulator

1. Connect the regulator to the CO2 tank.
2. Attach the regulator to the back of the collar or the freezer.
3. Connect the tubing from the regulator to the kegs.

Prepare the Keezer for Use

Now that your keezer is constructed, it's important to prepare it for use properly.

Step 1: Clean and Sanitize

Before using your keezer, clean and sanitize all parts that will come into contact with your beer. Use a food-grade sanitizer and rinse thoroughly.

Step 2: Carbonate and Serve

1. Fill your kegs with beer and add priming sugar or force carbonate using CO2.
2. Connect the kegs to the CO2 tank and adjust the pressure to the desired level.
3. Open the faucet and enjoy your perfectly chilled beer!

Step 3: Maintenance

Maintaining your keezer is essential to ensure optimal performance. Clean the faucets and lines regularly and replace any worn or damaged parts.

Conclusion:

In conclusion, building your own keezer can be a fun and rewarding project for any craft beer enthusiast. By investing the time and effort to build a customized keezer, you can enjoy your favorite beers at the perfect temperature and even serve them on tap.

With a little time and effort, you can have your very own custom keezer to enjoy for years to come.

FAQ:

What is a keezer?

A keezer is a freezer that has been converted into a kegerator. By installing a temperature controller and a beer dispensing system, you can control the temperature of your beer and serve it on tap.

How does a keezer work?

A keezer works by regulating the temperature of the freezer to keep the beer at the desired temperature. The temperature controller turns the freezer on and off as needed to maintain the temperature you have set.

What size freezer do I need for a keezer?

The size of the freezer you need for a keezer will depend on how many kegs you want to store. Typically, a 7 cubic foot freezer can fit two to three kegs, while a 14 cubic foot freezer can fit up to eight kegs.

How many kegs can fit in a keezer?

The number of kegs that can fit in a keezer will depend on the size of the freezer and the size of the kegs. As a general rule, a 7 cubic foot freezer can fit two to three kegs, while a 14 cubic foot freezer can fit up to eight kegs.

How much does it cost to build a keezer?

The cost of building a keezer will depend on the size of the freezer, the components you choose, and whether or not you already own any tools or equipment. On average, you can expect to spend between $500 and $1000 to build a keezer.

Do I need to drill holes in my freezer to build a keezer?

Yes, you will need to drill holes in your freezer to install the components for your keezer, such as the faucets and temperature controller. However, many keezer conversion kits come with pre-made templates to make the process easier.

Can a keezer be used as a fermentation chamber?

Yes, a keezer can be used as a fermentation chamber by adjusting the temperature controller to maintain the desired fermentation temperature.

What temperature should I set my keezer to?

The ideal temperature for a keezer will depend on the type of beer you are serving. Generally, you should set the temperature between 38°F and 45°F for most beers. However, certain styles, such as lagers, may require lower temperatures.

How do I clean my keezer?

To clean your keezer, you will need to follow a few simple steps:

1. First, unplug your keezer and remove all the kegs and components from inside.

2. Next, mix a cleaning solution of hot water and a non-abrasive cleaning agent, such as PBW or OxiClean. Follow the manufacturer's instructions for the cleaning agent to ensure that you use the correct amount.

3. Use a soft cloth or sponge to apply the cleaning solution to the inside surfaces of the keezer, including the walls and floor. Be sure to clean all areas thoroughly, paying special attention to any spots or stains.

4. Allow the cleaning solution to sit for the recommended amount of time, usually around 15-20 minutes.

5. After the solution has had time to work, use a clean cloth or sponge and hot water to rinse away all traces of the cleaning solution. Be sure to rinse all areas thoroughly, including any hard-to-reach areas.

6. Once you have rinsed the keezer, use a clean towel or paper towels to dry all surfaces completely.

7. Finally, replace all the kegs and components inside the keezer and plug it back in.

It is recommended that you clean your keezer every few months, or as needed if it becomes dirty or stained. By following these simple steps, you can keep your keezer clean and in good working order for years to come.
