Yes but I think to what theyre referring to is that caguama, is also a slang term used in Mexico and other Latin countries I believe, for a 32 oz beer. Just like we call 24 ozrs tallboys, mufflers, etc. Back on subject, theyre definitely diff beers, Ive had both, and not a fan of Corona Extra, never have been. Corona Familiar is nuttier, maltier, and isnt bad at all IMHO. Also our beloved BA site lists Corona E asn American Adjunct Lager, and Familiar as a Vienna Lager.
