The Perfect Water Temperature For Coffee Brewing
At different times in the past and many cultures, coffee was almost boiled with water to form a thick, dark, and bitter drink. With the journey to conquer the world of coffee, we have found better ways to brew. With useful scientific knowledge, a traditional belief has been established that coffee must be brewed in hot water. And never in the history of coffee has taste been better than these decades; However, in the third wave, art in the opposite direction of science recognized cold-brewed coffee (cold brew) as a way to drink coffee without temperature.
Why must brew coffee with hot water?Today, the popularity of Cold brew has made every basic concept of making coffee in hot water suspicious. Temperature, perhaps the most common form of energy used in making coffee. And there are two reasons for this;
- First, the hotter an object, the more energy it has. Therefore, the hotter it is, the more the molecules (or atoms of matter) vibrate (i.e., the higher the kinetic energy);
- Secondly, temperature follows the rule of energy conversion, going from high energy molecules to less energy molecules.
