in most cases i think the plural of beer is "beers" .. just sounds better .... but i also agree that it depends on where i am drinking my beer(s) who i am with or how much "beer" or how many "beer(s)" i have had. thomas's argument seems conradictory, when a person asks for 3 "beers" it should be understood that he/she is asking for it to be in some type of container. or i could be saying that i want 3 beer(s) meaning i want a canadian, a blue and an ex.. ergo 3 different beers.
