Will the acidity of cold extracted coffee be reduced?

Generally speaking, yes, cold extracted coffee is less acidic than hot brewed coffee.

This is the result of coffee powder being exposed to lower temperatures. Like most chemicals, compounds in coffee dissolve more easily at high temperatures, while some compounds do not dissolve at all. As a result, some of the more acidic compounds do not enter the drink at all.

While this is good for people with sensitive stomachs, it also means that cold coffee may not be as healthy as hot coffee. These same chemicals (such as chlorogenic acid) are key to the health benefits of coffee.

Not everyone has the time or desire to prepare cold coffee from scratch, which has led companies like Kohana to create pre-brewed cold coffee that can be blended immediately. These ready-made cold brewing drinks are perfect for travel, or camping, as a single 32-ounce container for cold brewing concentration and up to 15 x 6 ounces of service.

How to make cold extracted coffee

A simple way to make cold-extracted coffee is to soak the coarse powder in a kettle with cold filtered water.

When making coffee, the weight is more accurate than the volume. In the French kettle, 15 grams of water is needed for every gram of coffee. This is a little less than a regular cup of coffee, but the longer you are in contact with the coffee grounds, the more solids will be extracted as a whole.

Stir for two minutes, make sure all the grinding powder is in contact with water, and then put it in the refrigerator overnight.

When you come in the morning, use the kettle to slowly and steadily filter out the ground coffee, then pour yourself a cup of cold coffee.

As coffee making becomes a craft and trade, you can try to filter your cold coffee powder in many ways to suit your taste. Instead of pressing the kettle to filter, try soaking the coffee powder in a tea bag. The tea bag will help your brew remove more sour taste, let the taste show and steal the limelight.

Some enthusiasts use double filtration when grinding; first use two bags with paper filters, and then use a nut bag to get a cup of sweet cold coffee.
