Caryl Mclaen: Beer is bad to start with. But yes it will go flat.

Pattie Vold: You must be very young or very inexperienced, otherwise you would know that there is no such thing as a bad beer!

Rosie Travino: Yes beer can go bad--we call it skunky beer. It has a bad smell and no fizz. But, on an up note, you can still cook with it.

Margart Stimpert: It'll go flat and taste skunky. Corona will then buy the spoiled beer and sell it as "imported Mexican" beer.

Renay Billiar: Yes, it loses it's fizz and the taste will go. There is bacteria (yeast) it beer, and it goes bad.
