Wine question

[CJ]

Hi...Don't know if I am in the right place or not...I wanted to purchase some wine for a friend who just got a big promotion. He works for a large supermarket chain and has a vast knowledge of wines and has probably tried most. He is even putting a wine cellar in his new home. He is very wine savy and I am not. What would be a good choice?, something special, I know he likes Merlots.
Thanks for your help!!!!!
