About theft of wine, Irish?

I am looking for the title of a movie a few years ago. It was aobut a group of friends (2 guys and a girl) that decide to steal a bottle of wine from a rare cask that is going to be auctioned off. The one guy is very intelligent, and poses as a wine conniseur.I believe it is an Irish movie, but I am not sure.

Pretty sure you're talking about The Angel's Share (whiskey not wine though).
