A while back I was into experimenting with different varieties of the 40 ounce variety.
Colt 45 - Didn't like it, not very strong as far as malts go.
Steel Reserve - This is the ultimate malt beer in my area... 8.1% alcohol by volume! Two 40 ounce bottles knocked me on my ass! Taste is tolerable
King Cobra - Decent for malt beer, tastes a lot like Bud (both made by Anheuser Busch), good "beginners beer" at 5.9%
There are more that I can't think of right now.......
