You should probably use int() then::

      def alcohol(self):
          return 
((int(self.hydro_init)-int(self.hydro_final))*0.00036251)*10

This is because you do not call the method, but you just reference it.

To call it you need to add perenthesis::

     current_brew.alcohol()

Unlike VB you must state explicitly that you want to call a 
function/method. You can pass a funcion like any other object in Python.

You could even do::

get_alcohol = current_brew.alcohol
get_alcohol()
