Surprised nobody has mentioned coors lite? It's like drinking flat fizzy water with a slight hint of hops... and not enough alcohol to help you get over it!
ergh.
However I take Little Guys point about beers like that being better suited to certain climates e.g refreshing beers for hot climate.
That's essentially all Coors is good for LOL!!! Though I also occasionally have it if I'm driving to a local bar and want one or two since the lower percentage is advantageous. I'm almost salivating now at the feeling that comes from drinking an ice cold can or pint(never as good with bottles as it's harder to drink fast) after a blazing hot Southern Ontario day, so refreshing and even at a lower percentage can hit you a little hard if your dehydrated.
Another thing I didn't really mention is the North American beers(especially American) are often brewed with rice as either a supplement or replacement of hops/barley. Budweiser, Coors I know have high rice quantities. Asian beers often use rice as a primary ingredient as well. This is a big factor in their smoothness and a lack of "punch" in their flavour.
I usually drink Busch cans at home, it's a 4.7% beer, but it's essentially one that needs to be chiled and chugged. It's fairly good value for price as well since some imports as Taff stated are ridiculously expensive here. At a bar I'll vary things up more depending on establishment, time of year, any house specials etc.
The most absurd thing about United States beer is that you can't legally sell it to anyone under....
21 FFS!!!!!
As for worst beer I've ever had....on tap I had utterly rancid Steamwhistle at bar in St. Catharines called "The Mansion House" it's an older bar (200 years old is actually more like ancient by NA standards) and I know Steamwhistle uses odd preservatives so it may have been a combination of the brand or perhaps something wrong with the bars equipment, not having cleaned their lines or storing a beer with less preservatives poorly may have made for a shocking combo. It was virtually undrinkable, I barely finished my glass(and I had been forewarned by regulars how atrociuos it was, nor do I have a good sense of smell/taste).
I've had a couple bad micro brewery ones in my time but won't really trash them to much, often it's new startups looking for a new flavour or niche, sometimes it works sometimes it dosen't and anything that challnges the awful beer cartels here is good in my book!!!
Anything in a 40 Oz. is pretty much gross, Maximum Ice, Olde English Malt Liquor almost makes me want to gag thinking of it, I remember vomiting once on taste alone after chugging the end of a 40 of Labbat Blue...ugggghhh.
