how does property propagation work

I have been trying to figure out property propagation but cannot find enough 
information in the w3C's documents. For example, I loaded the wine ontology 
into the Protege editor and then viewed the ontology using Protege's OWL 
plugin and ez-OWL plugin (the ez-OWL plugin displays the ontology in a 
visual format). What I found is that the ConsumableThing class has the 
following properties listed under it: hasFlavor, hasSugar, producesWine, 
hasMaker, hasBody, madeIntoWine, locatedIn, and food:madeFromFruit. I think 
I figured out the last one but where are all the other properties coming 
from? I have searched over the actual wine.owl and food.owl documents 
several times but cannot see the link. Does anyone have an idea? Thanks.
