I used to make beer every week to satisfy my "beer-snob" tastes. I did this for four years; brewing everything from Belgian Whites to Imperial Stouts. Once I became a father, contraints on time & money forced me to settle on a "house beer", so I now have Yuengling Lager on tap in my house.
I am as much of a beer purist as the next guy, but when the only reasonably priced beers are somewhat bland "American Premium " styles, I don't see anything wrong with spicing it up a bit. Clamato does the trick nicely.
Maybe its a regional thing, but many people around here (rural Pittsburgh area) mix tomato or V8 juice with their beer. I guess it comes from years of drinking Iron City (blechhh!).
Oh well..........so much for trying to force my tastes on everyone else.

P.S. There is also "Beefamato". Not even I will try this.
