Champagne and Grape Juice

I have recently started to think about purple cocktails again, maybe it's because I've been in touch with Nailcote again or maybe it's because we have a cupboard full of champagne (left over from our engagement party!)  Spookily Hayley emailed me a link today from Brides.com.  (She was just taking a quick break from her university assignment, honestly!)

Apparently adding grape juice and a few berries to champagne turns the drink a nice purple colour.

I can't comment on the taste, but I'm sure at some point in the near future I shall be trying out!  Anyone care to join me...?
