Coffee Brown "Granite" advice

We are in the process of purchasing coffee brown "granite" for our kitchen countertops. Is there anything I need to know about it, i.e., should it be sealed or no sealing, daily care, etc. I'd like to start off on the right foot. I have been trying to search for any topics on coffee brown "granite" and have not been successful. Thanks for this informative forum !! I never knew there was so much to know about "granite."
