Choosing the Right Equipment
When it comes to kegging cold brew coffee, selecting the right equipment is essential for a successful and enjoyable brewing experience. There are a few key factors to consider – the keg, the dispensing system, and the size of your setup.
Selecting the Right Keg
The first step in kegging cold brew is to choose the right keg. It is important to use a keg specifically designed for beverages, such as a Cornelius (Corny) keg or a ball lock keg. These kegs are made from stainless steel and provide airtight seals, ensuring the freshness and quality of your cold brew.
One important consideration when selecting a keg is its size. Kegs are available in various capacities, typically ranging from 1.5 to 5 gallons. Think about how much cold brew you plan to brew and consume at a time, as this will help determine the appropriate keg size for your needs.
Choosing the Right Dispensing System
In addition to the keg, you will need a dispensing system to serve and enjoy your kegged cold brew. Two popular options are a draft system or a nitro cold brew system.
A draft system typically utilizes a CO2 tank and regulator to provide carbonation to your cold brew. It allows you to control the carbonation level and provides a crisp and effervescent texture to your beverage. On the other hand, a nitro cold brew system infuses nitrogen gas into the cold brew, creating a smooth and creamy mouthfeel, similar to that of a Guinness beer.
Consider your preferences and desired texture when choosing between a draft system and a nitro cold brew system. Both options have their own unique benefits and can enhance the overall drinking experience.

The size of your setup is another crucial aspect to consider when kegging cold brew. Assess the available space in your kitchen or brewing area and ensure that your chosen keg and dispensing system can fit comfortably.
It is also important to think about the amount of cold brew you plan on brewing. If you anticipate consuming a large quantity of cold brew regularly, a larger setup with multiple kegs may be more suitable. Alternatively, if you prefer smaller batches or have limited storage space, a smaller setup with a single keg might be the better option.
By considering the keg, dispensing system, and setup size, you can ensure that you have the right equipment for an efficient and enjoyable cold brew experience.
Preparing Your Cold Brew
Now that you have the right equipment, it’s time to dive into the process of preparing your cold brew. From grinding the coffee beans to determining the coffee-to-water ratio, each step plays a crucial role in achieving the perfect cold brew.
Grinding the Coffee Beans
To begin, select a high-quality coffee bean and grind it to the appropriate consistency. For cold brew, a coarse grind is typically recommended. This allows for a slower extraction, resulting in a smoother and less acidic cold brew.
Investing in a burr grinder is recommended as it provides a consistent grind size, ensuring optimal extraction. Avoid using a blade grinder, as it can produce uneven grounds that may lead to a subpar brew.
Determining the Coffee-to-Water Ratio
The coffee-to-water ratio is an essential aspect of cold brew preparation. It determines the strength and flavor profile of your final product. A general starting point is to use a ratio of 1:4 or 1:5, meaning one part coffee to four or five parts water.
However, feel free to adjust the ratio to suit your taste preferences. If you prefer a stronger brew, increase the amount of coffee. Conversely, if you prefer a milder brew, you can decrease the coffee-to-water ratio.
Brewing Time and Temperature
Once you’ve determined the coffee-to-water ratio, it’s time to let the magic happen. Cold brew typically requires a longer brewing time compared to other brewing methods. Allow your mixture to steep for 12 to 24 hours at room temperature.
During the steeping process, the cold water slowly extracts the flavors from the coffee grounds, resulting in a smooth and rich concentrate. After the desired steeping time, strain the mixture to separate the grounds from the liquid.
Remember, cold brew is brewed without the use of heat, so it’s important to avoid exposing your brew to high temperatures. This will ensure that you achieve the desired flavors and avoid any bitterness or over-extraction.
