What is Kegging Cold Brew Coffee?

Kegging cold brew coffee involves transferring your brewed coffee into a keg and pressurizing it with carbon dioxide (CO2).
This method allows you to store and serve your cold brew coffee on tap, just like a draft beer system.
By utilizing kegs, you can enjoy freshly poured, icy-cold coffee at any time, without the need for individual bottles or containers.

Why Keg Cold Brew Coffee?

Kegging cold brew coffee offers several advantages over traditional storage methods.
Firstly, kegging allows for easy dispensing of your coffee, ensuring that every pour is perfectly chilled and smooth.
The pressurized CO2 also acts as a natural preservative, extending the shelf life of your cold brew without compromising its quality.
Additionally, kegs are reusable and eco-friendly, reducing the need for single-use bottles or cups.
Lastly, serving cold brew coffee on tap adds a touch of sophistication to your home or coffee shop, impressing your guests and customers.

How to Keg Cold Brew Coffee

Now that you understand the benefits of kegging cold brew coffee, let’s dive into the step-by-step process of kegging your own brew.

Step 1: Brew Your Cold Brew Coffee

Start by brewing a batch of cold brew coffee using your preferred method.
Remember that cold brew requires a higher coffee-to-water ratio than traditional brewing methods to achieve a concentrated flavor.
Experiment with different coffee bean varieties and grind sizes to find your perfect combination.

Step 2: Filter and Chill

Once the brewing process is complete, filter the coffee concentrate using a paper or mesh filter to remove any sediments.
Transfer the filtered brew to a clean container and place it in the refrigerator to chill.
Ideally, let it chill overnight to allow the flavors to develop fully.

Step 3: Transfer to the Keg

Carefully transfer the chilled cold brew coffee into a clean and sanitized keg.
Avoid any contact with oxygen during the transfer to maintain the freshness and quality of the coffee.
Leave some headspace in the keg to account for the pressurization process.

Step 4: Carbonate Your Cold Brew

Connect a CO2 regulator to the keg and set the pressure according to your preference.
We recommend starting with a pressure of around 25 psi and adjusting to taste over time.
Allow the CO2 to carbonate the cold brew for at least 24 hours, but longer if you prefer a more carbonated result.

Step 5: Serve and Enjoy

Attach a tap or dispenser to the keg and refrigerate it to maintain a consistent cold temperature.
When ready to serve, simply open the tap and pour a refreshing glass of your homemade kegged cold brew coffee.
Don’t forget to share the experience with your friends, family, or customers!

Disadvantages of Kegging Cold Brew Coffee

Despite its numerous benefits, kegging cold brew coffee also has a few potential drawbacks.

Cost of Equipment Setting up a kegging system requires initial investment in equipment, including kegs, regulators, taps, and CO2 cartridges.

Important Tips for Kegging Cold Brew Coffee

To maximize your kegging cold brew coffee experience, here are some important tips to keep in mind:

  • Regularly clean and sanitize your kegging equipment to prevent off-flavors or contamination.
  • Experiment with different coffee bean origins and roast levels to discover unique flavor profiles.
  • Use higher-quality water to brew your cold brew coffee, as it can significantly impact the taste.
  • Consider adding flavoring syrups or spices to your cold brew coffee before kegging for additional variety.
  • Label your kegged cold brew coffee with the brew date to ensure freshness and rotation.

Difference Between Kegging and Bottling Cold Brew Coffee

One common question that arises is the difference between kegging and bottling cold brew coffee.

Kegging Cold Brew Coffee

Kegging involves transferring the brewed coffee concentrate to a keg, pressurizing it with CO2, and serving it on tap.
It offers advantages like effortless dispensing, extended shelf life, and consistent quality.
However, it requires additional equipment, such as kegs, regulators, and taps, and takes up more space.

Bottling Cold Brew Coffee

Bottling cold brew coffee involves transferring the brewed coffee concentrate to individual bottles or containers, which are then sealed and refrigerated.
This method is simple and requires less equipment and space.
However, the absence of pressurization means that the shelf life may be shorter, and pouring may be messier without a dispenser.

FAQs (Frequently Asked Questions)

Q1: Can I add milk or cream to my cold brew coffee before kegging it?

A1: Yes, you can definitely add milk or cream to your cold brew coffee before kegging it. It’s a matter of personal preference and taste. However, keep in mind that adding dairy products may change the taste and consistency of your cold brew, so it’s recommended to do some experiments and find the right ratio that suits your taste buds. Start with small amounts and gradually increase until you reach your desired taste and flavor.

Q2: How long can I store my kegged cold brew coffee?

A2: Kegged cold brew coffee can be stored for up to two weeks if stored in a refrigerator at a temperature below 40°F (4°C). However, it’s important to note that the flavor and freshness of the coffee may start to deteriorate over time. To ensure the best taste and quality, it’s recommended to consume your cold brew within the first week of kegging.

Q3: Can I carbonate my cold brew coffee in a keg?

A3: Yes, you can carbonate your cold brew coffee in a keg. Carbonating cold brew adds a refreshing fizziness to the beverage, similar to carbonated sodas. To carbonate your cold brew, you will need a kegging system that allows for carbonation, such as a kegging CO2 system. Follow the instructions provided with your CO2 system to properly carbonate your cold brew. Keep in mind that carbonation may alter the taste and flavor of your cold brew, so it’s recommended to start with small amounts of carbonation and adjust according to your preference.

Q4: Can I keg my cold brew coffee without a kegging system?

A4: While it’s technically possible to keg cold brew coffee without a kegging system, it may not provide the best results. Kegging systems are specifically designed to maintain the freshness, carbonation (if desired), and flavor of the cold brew. Without a kegging system, you may encounter difficulties in properly sealing the keg, maintaining the desired temperature, and achieving the optimal taste. It’s recommended to invest in a kegging system or borrow one from a friend if you want to keg your cold brew with optimal results.

Q5: Can I add sweeteners or flavorings to my kegged cold brew coffee?

A5: Absolutely! Adding sweeteners or flavorings to your kegged cold brew coffee is a great way to customize it to your liking. Whether you prefer sugar, honey, syrups, or even spices like cinnamon or vanilla extracts, you can experiment with different combinations to find your perfect blend. However, it’s best to start with small amounts and gradually increase the quantity to achieve the desired taste without overpowering the natural flavors of the cold brew coffee.
