Do I have to brew cold brew coffee at room temperature or in the refrigerator?

You can keep your cold brew coffee at both temperatures, depending on your preferences. At room temperature, it achieves a more robust flavor. However, if you brew it in the refrigerator, you should be able to get the same results by simply allowing it to brew for a little longer.

However, regardless of the temperature at which you choose to brew your cold brew, make sure the cold brew machine or container you use for brewing is closed. This will keep other odors from influencing the cold brew.

What is cold brew coffee?

A cold brew is a coffee that has been cold-extracted or “brewed” with cold/room temperature water. As a result, the coffee is exposed to water for a time ranging from 12 to 18 hours, since cold water does not extract the flavors and aromas of coffee in the same way as hot water.

Some taste components and caffeine are removed at room temperature (or slightly cooler) and after prolonged contact with water, many bitter oils and unpleasant acids are left behind.

As a result, the drink is more concentrated and thoroughly extracted, but less bitter than ordinary coffee. This delicate and eye-catching coffee may be served hot or cold, dissolved in water or over ice, with milk or lemon, tonic water, and so on. Many individuals believe that cold brew is perfect for producing drinks because of its properties.

What is the recipe for cold brew coffee?

This recipe calls for 4.6 parts water to 1 part coffee. There are formulas ranging from 3:1 to 10:1, and each produces extremely diverse outcomes. The ideal is to try each one to find out which one best fits your taste. 

For this recipe, you are going to need the following ingredients:

600 ml filtered water; 130 g coarsely ground coffee; 1 paper coffee filter (previously scalded in hot water) 

Preparation method

Add the coffee and cold water to a large mixing bowl and swirl a few times until well combined. Set aside for at least 12 hours, covered. 

After brewing, move the coffee from the original container to a new container, passing it through a paper filter or a fine weave cloth. It is critical that this transfer be gradual for the filter not to overflow.  Also, be cautious not to break the paper filter, since the desirable is a residue-free drink at the end.

Now all you have to do is chill your cold brew and it is ready. The drink may be refrigerated for up to a week in an airtight container. 

Curiosities about cold brew coffee

It tastes sweeter

Cold brew coffee tastes significantly sweeter than ordinary coffee because it has 67 percent less acidity than hot brew. Cold brew may be as full-bodied and smooth as hot brew, but without the harsh aftertaste. 

It enables the appearance of a new flavor profile. The oils and acids that accompany hot coffees are softened when prepared cold. As a result, the flavor profile is greater, emphasizing the fruity, vanilla, and milk chocolate characteristics of the coffee beans.

Cold Brew Coffee has a higher caffeine content than regular coffee

Because of the lengthy steeping process, the coffee-to-water ratio in the cold brew is around 1:60, as opposed to the drip coffee ratio of 1:20. Regular coffee is also sometimes diluted with milk, cream, or water, lowering the caffeine dosage. 

A 16-ounce cup of cold brew has around 200 mg of caffeine, but a cup of hot brew contains between 160 and 180 mg, depending on the coffee beans used, the length of time the coffee is steeped, and the amount of milk, cream, or water used to dilute the brew.

Cold brew is a better option for those with sensitive stomachs

The heat utilized in the production of normal coffee might result in bitter flavor characteristics. Because no heat is used in the production of cold brew, the flavor is smoother and the coffee is less acidic. Because cold brew is more acceptable, it is better suited to individuals who have sensitive stomachs or suffer from acid reflux.
