Talk to them. When they respond you'll see the "Present" option. It's only there for the first thing they say to you, so if you enter past their first comment you'll have to back out and talk to them again.

Once you hit the assigned button a menu screen pops up. Items they can accept will be there. Mercedes accepts several gifts, but she likes Cloudwine best, and like many other NPCs she has different dialog when you give her favorite item.
