Holiday Gift

[lb]

I would like to give a nice bottle of wine to each of my bosses for the holidays. First of all, one of them is a wine connoisseur, and enjoys a French Bordeaux or White Burgandie. I was wondering if there's a specific one you can recommend that is preferred, or what to look for when selecting this. And secondly, what type of wine is good to give to the others (I'm not sure what they prefer) and is of the same value? Thanks.
