This is not an issue of product liability in my eyes. It was not like the buyer was unaware that alcohol has the potential to make him drunk. Whatever the law says, all of the consequences were his fault alone morally when he began to drink that first drink. Also, last time I checked, beer producers or vendors never tried to claim that they their products don't get people drunk. Companies aren't or at least shouldn't be liable when the risks of a product are known ahead of time.
