Cold brew coffee, as the name suggests, has nothing to do with cold coffee (the one you forget near the computer keyboard). In a coffee maker or Espresso machine, “hot” coffee appears when hot water is mixed with ground coffee beans. With the help of the temperature, the water extracts the aromatic compounds from the coffee, taking on this beautiful brown / black color.


First, what cold brew coffee exactly and some pieces of information about this magical beverage.

What is cold brew coffee exactly?

It’s not a kind of coffee, but rather a method of brewing it. It involves letting roasted coffee beans stand in water at room temperature, or cold, for an extended period. No ice is required. Since no heat is used, this method allows a unique flavor profile to be extracted from the roasted coffee.

A singular taste

Cold-brewed coffees are usually less acidic and sweeter than traditional coffees, providing a smooth and refreshing beverage

says Paula

Brounstein, Research and Development Scientist at Keurig Canada. Because cold brewing prevents the oils in the beans – often acidic – from being released, we’re also better able to enjoy the subtleties between the different varieties of beans.

Cold, but you can drink it hot 

It brews cold but can be enjoyed on ice cubes as well as warmed in the microwave or a saucepan.


Moreover, some people drink it as it is, after the infusion, or dilute it in water or milk, with a hint of sugar or not.

Simple and eco-friendly

You don’t need a scientific laboratory to develop your “cold brew”. All you need is a good cup of coffee, a filter, and patience. The process (explained below) does not require electricity either, unlike regular hot brewing.

Prolonged storage

Cold-brewed coffee can be stored in the refrigerator for up to two weeks. Some people keep it even longer, but the beverage may be somewhat denatured.

Which coffee beans to choose to prepare cold brew coffee? 

Cold brew coffee, coffee beans

Cold-brewed coffee can be made with the coffee of your choice. Choose the beans with the flavor profile that suits you and choose a coarse grind. For optimal flavor, grind the beans just before brewing.


In recent years, cold-brewed coffees have become very popular with consumers. There are many recipes for cold coffee, but one that is attracting a lot of interest is cold-brewed coffee, or “cold brew”. 


Although cold-brewed coffee has been around for several centuries, the craze about it has only recently resumed. It is a more time-consuming brewing method that allows coffee lovers to get a slightly different note in their coffee, while still being refreshed.

Some cafés and roasters even market their ready-to-drink cold-brewed coffee. Watch out for their sugar content, though! A nitrogen-carbonated variant, called nitro cold brew, is served in barrels in some establishments. Visually, this drink looks very much like a Guinness beer!

Bartenders love the cold brew for the bitterness it can bring to cocktails. Some use it as is, while others use it as a syrup to add a sweet touch. Also, since cold brewed coffee can be stored for a few days, it is a convenient ingredient for a food service establishment.
