Absolutely right sir @jesustiano.
From the picture you can see, there is still coffee down there, and of course, the flavor of the coffee remains. Even though it's mixed, there will always be a taste of coffee in it. That's why I said only robusta is suitable. Thank you for stopping by sir.

Thank you for answering with such a good vibe an energetic greeting, big hug bro :)

You are welcome :) happy nice weekend sir
