Haven't added to this list in a long time, but thought I'd get it down on electronic paper. Current list of countries I have beer bottles (which contents I drank) from:
United States Of America
This is 45 countries and as you may notice, contains places that may not be on your current list of countries of the world, which is endlessly debatable. I figure these are "beer" countries: if they have a distinctive national style and/or advertise on their label that they are from a particular country, I figure that merits inclusion in the list of "beer" countries.
