Cold brewing is a coffee brewing process where coffee is extracted into cold water over a long period of time (often over 12 hours). The water in the process is often either room temperature or cold. After extraction, the coffee is strained with either a french press or with the help of a strainer and filter paper or cloth.
Normal and cold brew coffee have some differences in flavour and chemical composition because while making cold brew, the coffee does not come into contact with boiling water. Cold brew typically contains less caffeine and acids than traditional coffee and is less bitter than its counterparts. As it is often mixed with milk or water, cold brew is sometimes extracted a bit stronger than regular coffee.
Cold brew allows the different flavours and nuances in coffee to shine, so especially interesting choices for cold brew are light roasts, that have various fresh flavours. Another thing to try is to prepare natural processed coffee with cold brew. The sweetness of the coffee berry is present in natural processed coffees, so it makes your drink sweeter as well.
