A 3/4” to 1” head of foam allows
             the natural carbonation to escape,
       enhancing the flavor and drinkability,
    and keeps the customer from filling
   up too fast.

  To produce a proper head or collar of foam: 

  » Place the neck of the bottle or lip of
     the can over the edge of a clean
     glass or cup. 
  » Quickly raise the bottom of the bottle
     or can to a high angle, causing the
     beer to agitate in the glass.

Don’t pour the beer by the “down-the-side”
method. It minimizes the foam, making
the beer look flat and taste gassy.

» Lower the bottom of the bottle or can
to reduce the flow until the foam rises
to the rim. For most glasses, a 1” foam
collar is ideal.

»  Open bottles or cans where they are served,
whether bar or tableside, to prevent foaming
over when walking to the customer.
