Isn't Sam Adams a little more than a craft beer? Either way, the reason to own BUD is entirely unique and does not apply to Sam. Anheuser has advertising, legal, and political advantages that few other companies in the world enjoy. Those advantages have been around for decades and will continue for decades to come.
The reason to buy Sam Adams is this is a truly an American Icon brand built the way we do it here in the USA.. As an American this is important to many here in the USA. If I were Brazilian, I would fee the same about BUD.
