To start our journey in the not-so-mysterious land of cold brew coffee, first let us understand the real meaning of this peculiar type of coffee.
What is Cold Brew Coffee
Mostly confused and used interchangeably with iced coffee, be informed, although being cold, it is far from being similar to iced coffee. Cold brew coffee is brewed over longer durations (5 to 24 hours) and there is no heat involved in the methods of preparing one. It is made by brewing coffee grounds (slightly coarser than normal) with cold water or room temperature water for a longer duration of time, be it with any method (Cold drip and immersion method).
Its variant Nitro coffee, which is turning lots of heads, is a cold brew coffee that is infused with nitrogen gas. It is served from a tap on the beer keg. This makes it creamier and sweeter in flavor. However, one thing is of prime importance that nitro coffee is never mixed with milk, cream, or sugar; simply because there is no need for these ingredients. It is already creamy and sweet in texture and taste.
The best thing about cold brew is the time it takes to prepare in comparison with other coffee types. A longer amount of natural brewing and no involvement of heat reduces the number of acids from the final extract and makes it a healthier drink. This is one of the most important reasons it is gaining traction among coffee drinkers all over the world.
The growth in the numbers of cold brew drinkers can be understood by the fact that the global Cold brew coffee market size was valued at USD 339.7 million in 2018 and is expected to grow at a CAGR of 25.1% from 2019 to 2025, according to a report by Grand View Research, Inc.

Understanding all the above trends, one might ask what all the reasons behind the booming shift towards this particular type of coffee are? Let us look at the detailed answer to this brewing question.
How to Make a Cold Brew Coffee
The easier process of making cold brew coffee is Immersion which is talked about everywhere. The most important benefit of this method is the smaller number of required things that go into making it, reducing hassles so that even a novice can prepare and enjoy it truly.
Solubility is one of the most important factors while preparing a cold brew. Temperature is key to the extraction of flavor from the beans. Hot water makes it easier to extract flavor quickly, however in cold brew, as the name suggests cold water or room temperature water is used. Therefore, a large amount of time is needed. This actually becomes a blessing in disguise for the coffee.
Also, oxidation can lead to the absorption of different flavors by the coffee, therefore, cold brew coffee is best made in a jar with a lid. In light of all this information, let us look at the two most widely used techniques to prepare cold brew coffee.
1. Cold Brew Coffee by Immersion Technique
This is the easiest type of brewing method for cold brew coffee. In this method, right amount of ratio between coffee grounds and water is of utmost importance.
Generally, a 4:1 ratio between water and coffee is preferred. However, in some recipes, it is stretched out to the 10:1 ratio as well. Adding water to dilute the mixture when coffee is found to be strong is the right remedy afterward.
Apart from this coffee grounds are also needed to be coarsely grinded. As, the finer coffee grounds (used in espresso) results in cloudy coffee.
- 1 cup of coarsely ground coffee
- 4 cups of water
- 2 containers (with or without lid) and;
- Some coffee filters or some cheesecloth’s
- Place the Coffee Grounds – Place coffee grounds in the glass or plastic container and pour water in it following the given ratio of 4:1.
- Fill the container with water – Fill the container completely and cover the container with the lid or a cloth tightly, so that chances of oxidation can be largely reduced.
- Wait – Let the coffee steep for 12 hours or more.
- Pour the coffee – Pour the concentrate into another container by simply pouring it through a sieve covered with a cheesecloth. This will filter out coffee grounds.
- Enjoy – Ice along with other flavors can be added to the coffee before enjoying it.
To cut the amount of time needed to brew in this manner, the French press mentioned above is used by several coffee masters. Apart from this, several cold coffee brewers like Todd Simpson’s Toddy T2N Cold Brew System are already present in the market. These brewers make it easier to prepare coffee in less time, without compromising on taste.
2. Cold Brew Coffee by Cold Drip Method
This method needs an elaborate set of cold-brew coffee maker which adds water to the grounds slowly. The device is divided into 3 levels:
- On the topmost level ice and water is placed
- Middle levels hold the coarsely grounded coffee
- The third and the bottom layer is used to collect the brewed coffee
Water drips from the topmost layer onto the coffee grounds in the middle layer, gradually getting collected in the bottom chamber. This whole method requires approximately 5-10 hours, however, the taste of coffee from the cold drip system is slightly different from the immersion method.
There are several devices in the market that make use of this method. These are unique because they use their perforated rainmaker system to evenly distribute water over the coffee. This allows for optimal flavor extraction. If you are interested in this system, have a check on our guide about the best cold brew coffee makers to pick among the top sellers.
