Altadis USA has a very cool site that teaches you about the history and facts of cigars, and how to judge a good cigar, as well as how to store them. If you are new to cigars, or if you are a veteran and want to test your knowledge of cigars, this is an excellent information site.
You can also get a Certificado de los Maestros there.
