Here, the science of brewing becomes an art, as the most essential
ingredients are added to the boiling mix, before fermentation.  Unlike
before, there is plenty of space to work, for fear of a mistake.  It is
likely the sole responsibility of the manager here to decide exactly what
ingredients - and in what quantity - should be added.  The smell captivates
the senses, it is easy to see why the monastery is able to barter so
effectively.  
     A copper vat sits in the middle of the room, full of a dark liquid.
