Clamato is great. I have been drinking it since the early seventies, shortly after it was introduced to our market. $.25-$.75 a quart. Now, it's $5 plus for a half gallon. Oh, well.
For those who have never tried it, it's sort of sweet, tangy, and salty all at once. Great stuff. My daughter likes it too. Between us, we can polish off a quart in about 10 minutes.
I tried the beer/Clamato mix 4-5 months ago. I drank a couple of swigs and poured the rest down the drain. Nasty,nasty,nasty.
FWIW, "tomato beer" (beer and tomato or V-8 juice) or a michelada (beer and Clamato) are rather popular around here.
