Place all objects in a Hashtable or something similar and only put that
into context. Then pick the correct ones from templates. Something like
($biz here is a Hashtable):
---------------------------------
#set($beers = $biz.beers)
#set($people = $biz.people)
---------------------------------
or if you don't want all those objects to initialise up front, this
approach could be useful ($biz here is your class that knows how to pick
other useful objects):
---------------------------------
#set($beers = $biz.getObject("beers"))
#set($people = $biz.getObject("people"))
---------------------------------
where getObject() would only really get make an instance of the ones
that are being used. Those objects could even be stored (serialized)
somewhere in a database.
