Tab
(Unless you're into metallic aftertaste.)
But it wasn't as bad as some beverages that never made it to mass market. When I lived in a Midwestern city that was a trial area for new products, one summer we got to test (brace yourselves) lime beer and cherry beer.
They were two separate drinks, but they couldn't have tasted worse if they were blended. Notice you never got to try them in your town, right? You can thank us brave souls who used them for mouthwash.
