My AH can be intoxicated on cider, but if he adds in red wine (in fact any time he has red wine), he gets much much worse. Not hard to deal with, red wine just totally wipes him out, and he's not capable of anything more than extremely basic function, like walking (which isn't done properly). He can only have an extremely basic conversation, and even that can't be maintained.
I don't know why it's wine that specifically does it to him, he can have a large number of ciders and still be fairly functional, with walking/moving and talking.
