It was a fruit flavored clear sparkling water drink very much like Clearly Canadian. I had not thought about either in years but just saw Clearly Canadian at Publix and had not seen that stuff in a long time. I am currently traveling through Appalachia and started thinking the days of drinking a nice cold Appalachian.
It was very popular in at least Southern Ohio, Kentucky, and West Virginia as this is where I was romping around. I was out west a bit Colorado and South Dakota at the time but do not remember it being out there.
Clearly Canadian was very popular at time as well but Appalachian was way better the fruit flavor was more real tasting and the bubbles weren’t as harsh.

I can’t even find a mention of it doing a google search.
