what characteristic of coffee?

Please provide me with more context! "Characteristic of coffee" is very broad.

To give you a helpful answer, tell me what you're interested in:

* Are you looking for a specific characteristic? (e.g., flavor, caffeine content, origin, processing method)

* What are you using this information for? (e.g., writing an essay, choosing a coffee, starting a conversation)

The more specific you are, the better I can understand your needs and give you a relevant response.
