One that I like is called "Sarah's Patio Red" by Chrysalis.

I'm not sure I'd serve it to a "boss"...I think it's more of like a "Girls night In" on a summer night, hanging out on the back patio, kind of drink.
It's red, but you chill it and it's a bit bubbly...reminds me a bit of Lambrusco, actually.
I orginally bought it because I thought the bottle artwork was cute, but now I like to drink it in the summer if we are having burgers outside.
