What exactly the "dry" means in the "dry hop" expression ?
Does it refers to a dry flavor of hop in beer? Or because the hops were added to beer in a dried form? Could it be called or explained as "cold hop"? Or what? ...
EDIT: A THEORY/SPECULATION - Considering the hop history in the beer and when it started to be used to "dry hop". Could it be preferably used in a dried form to avoid contamination instead of its fresh flowers ? And so... "adding dried hop".
