Recently Two Brothers collaborated with a brewery in France on a long lost recipe that goes back to like the first brewery in Chicago.(hence the name, cross streets in Chicago) It was bottled but can't find anymore and my only current link is getting some on tap at 2 brothers.
Of course, I'd like to see about working on a clone for this and was putting it out there if there's any insight on this one. All I know right now is that its a Biere de garde.
