First off let me clarify that anyone posting Miller High Life here as their serious "worst" beer is signing up for a brand new, non refundable, non returnable ass whooping from Chriso's Whoopin's Inc. You will
not speak ill of The Champagne.
Now on to real "worst" beers.
Beer 30 Light. Someone already posted this. I have to second it.
I bought a 30 of Beer 30 Light in Madison, WI. I paid $9 for it. I was up there for a week's vacation. I brought 26 of those horrific cans of hydrogen-peroxide-tasting water home with me. And proceeded to give them, still full, all away to a friend 6 months later.
But more importantly...
MINHAS LIGHT.
It's the only beer that has ever - EVER - made me miss drinking Beer 30 Light. Minhas isn't even worth describing, it just tastes like rancid ass, nothing else.
Honorable mention:
Bud Light Lime.
Don't get me wrong, I'm not just hating on fizzy lime - case in point, I
will drink the crap outta Miller Chill all day long, it's actually delicious, especially when you're on a boat - but BLL is the polar opposite. The lime flavoring tastes like infection, the bud light tastes worse than usual, the carbonation isn't quite right, and it gives me the worst gut-rot I've ever had.
I would speculate about BL Lime-o-rita but I just can't be bothered to care any more. I'm done buying Anheuser flagship-line products. I am tired of falling for each gimmick they release. These days, I only want real, good craft beer, homebrew, or drinking-class American lager e.g. PBR, MHL, Grain Belt, etc. and not much in between there.
Anything with the label Shock Top can you know what on my you know who's.
