wine and caffeine?

I have read that a glass of wine is good for gallbladder. Is this true? Could it relax the bile duct helping with lodged stone? I also read that men who drink coffee have less gallbladder problems that others who don't. If this true why would it not be same for females?

This is different that other articles I have read. I can't remember the exact website I read this on but I read it twice to make sure I wasn't missing anything. Tweet
