Cold brew coffee has become a staple in many coffee shops and homes due to its smooth, rich flavor and ease of preparation. Unlike hot brew methods, cold brew involves steeping coarse-ground coffee beans in cold water for an extended period, usually 12 to 24 hours. This process extracts the flavors and oils from the coffee without the bitterness that can come from hot water. Making large quantities of cold brew, such as 5 gallons, is ideal for events, cafes, or for those who consume a lot of coffee. In this article, we will delve into the details of how to make 5 gallons of cold brew, covering the necessary equipment, coffee-to-water ratio, steeping time, and tips for customization.
Understanding Cold Brew Basics
Before diving into the specifics of making 5 gallons of cold brew, it’s essential to understand the basics of the cold brew process. Cold brew coffee is made by steeping coarse-ground coffee in cold water. The cold water extracts the flavors from the coffee more slowly, which results in a less acidic and less bitter taste compared to hot-brewed coffee. The key factors in making cold brew include the type and coarseness of the coffee grind, the coffee-to-water ratio, the steeping time, and the temperature of the water.
Choosing the Right Coffee
The type of coffee bean used can significantly affect the flavor of your cold brew. Arabica beans are generally preferred over Robusta for their more complex and nuanced flavor profiles. Within Arabica, there are numerous varieties and roast levels to choose from. Lighter roasts tend to have more acidic and fruity flavors, while darker roasts are richer and more bitter. For a balanced cold brew, a medium to medium-dark roast is often recommended.
Coffee Grind and Ratio
The grind of the coffee should be coarse. A coarse grind allows for the right amount of extraction during the steeping process. If the grind is too fine, it can lead to over-extraction and a bitter taste. The standard coffee-to-water ratio for cold brew is about 1:4 to 1:6 (one part coffee to four to six parts water). For 5 gallons of cold brew, you would need approximately 1 to 1.25 pounds of coffee, depending on your desired strength.
Equipment Needed
To make 5 gallons of cold brew, you’ll need a few pieces of equipment. The most critical item is a large container that can hold at least 5 gallons of liquid. This can be a food-grade plastic bucket, a stainless steel container, or a dedicated cold brew coffee maker designed for large batches.

What is cold brew coffee and how does it differ from hot brew coffee?
Cold brew coffee is a type of coffee that is brewed without heat, using cold water to extract the flavors and oils from the coffee beans. This process typically takes several hours, resulting in a smooth and low-acidity coffee drink. In contrast, hot brew coffee is made by pouring hot water over ground coffee beans, which extracts the flavors and oils more quickly. The main difference between the two is the flavor profile, with cold brew being generally sweeter and less acidic than hot brew.
The cold brew process also allows for a more controlled extraction of the coffee’s flavors and oils, as the cold water extracts the desirable compounds more slowly and evenly. This results in a coffee drink that is less bitter and has a more balanced flavor profile. Additionally, cold brew coffee is often less acidic than hot brew coffee, making it a great option for those who are sensitive to acidity. Overall, the unique brewing process and flavor profile of cold brew coffee set it apart from hot brew coffee and make it a popular choice among coffee enthusiasts.
