What characterizes decaf coffee?

Decaf coffee is characterized by the fact that most of its caffeine has been removed during the decaffeination process. This process involves soaking the coffee beans in a solvent, water, or carbon dioxide to extract caffeine while preserving the flavor compounds. The aim is to ensure that the coffee retains its typical taste profile while significantly reducing its caffeine content, typically to about 97% or more of the original caffeine.

Other choices do not accurately describe decaf coffee. For instance, brewing temperature does not determine whether a coffee is decaffeinated; any brewing method can be applied to both caffeinated and decaffeinated beans. Additionally, while flavor syrups may be used to enhance the taste of various coffee drinks, they are not inherent to decaf coffee itself. Lastly, decaf coffee can be made using various brewing methods, including cold brew, but this is not a defining characteristic of decaf coffee. The essence of decaf is fundamentally linked to its low caffeine content.
