Adding grapefruit flavor into a wheat beer?

[frankdontsurf]

Travelers Grapefruit Shandy...I'm not actually ready to brew this, but I wanted to know how it was made since I drink it often. Nowhere is there any specifics on how to add the grapefruit flavor in, what type of yeast is used, or the specifics of the grain bill. I start looking into it some more and it's not really a Shandy, since a Shandy is a mixed drink of beer and soda...

So what exact type/style of beer is a Travelers Grapefruit Shandy??

Or maybe I've been drinking it wrong, I just pour it in a goblet.

I would be interested also if someone has a grapefruit shandy recipe.
