I'm so glad you liked it. I'll have to pop in on the happy prompt fest as well!

Cheerwine is a very sweet cherry soda with an awesome name, made in North Carolina. It's local to the South, so you don't see it everywhere.

Sam and Dean were actually drinking "retro Cheerwine" which is sold in glass bottles and sweetened with cane sugar, like the legendary pony bottles of Coke. :)
