Are you sure about this, Garth.  If one replenishes the sugar, and
provided the alcohol content is not too high, yeast will revive and
continue the fermentation.  I am under the impression that the spent yeast
is the carnage after the food source runs low - the sugar, or the
pollution gets to great - the alcohol.
 
Is the heating process to rid the slurry of alcohol, or is it needed to
kill a pathogen which is a danger to the bees?
