Chrissi:
" an ornate crystal bottle with a large opal set into the stopper,
full of what Harry was quite sure was blood." OoP page 99, UK edition

I highly doubt it was blood. I suppose it could be have been red wine,
red liqueure or something like that. Is it an alcoholic drink instead?

Dan:
What makes you think it wasn't? I think it's very likely, actually. Blood is a very potent substance, not only biologically (as people have the nasty tendancy to die without it) but magically. Blood is life. With someone's blood, you have control over that person's life force (and all associations with it). Naturally, vampires run about the countryside drinking it. Magically sympathetic items don't get more hardcore than this.
