I haven't seen "Wine Cellar" yet.
Brewery: Got to lift the spirits of the folks with... well... spirits or beer! The more posh might want their wine so a wine cellar is useful, I guess.
Storage Rooms: We've got to have somewhere to put the firewood, food, dead servants and all the other stuff that may or may not be useful later.
Printing room: Aristocrats need fancy stationary to write their orders, speeches, memoirs, letters and porn. Let's just hope they don't mix them up. Good for publishing books when things are quiet.
