Cold brew coffee is better than hot brewed coffee? This has been proven through chemistry.

When coffee powder is mixed with water, chemical reactions take place. The soluble substances in the coffee are removed, creating a delicate, delicious extraction solution.

The solutes of instant coffee are best at 195 degrees F to 205 degrees F (about 90 degrees C to 96 degrees C), so coffee mixed with hot water will have a fuller “body”, flavor richer than cold brew coffee. Hot water also makes it faster to pull the soluble substances in coffee out of the coffee grounds but also makes them more volatile. This means it can evaporate into the air more easily, reach your nose and you’ll be able to recognize the aroma of the coffee.
