I am the cooper.  I split tree trunks.  I heat wood over fire.  I measure how big I want the barrels to be. The circle needs different sizes.  I need lots of wood.  You put stuff that I don’t know what it is inside.  It takes a long time to make a barrel.  You put chemicals and then heat it.  I drill a big hole for the wine to come out if they want it.  You make a stand for the barrel because the barrel can break.  I’d better make the metal part shiny to look nice.
