Saw this mentioned in an article, and it got me thinking... Is there regional pop you love? Maybe you didn't even know it was a regional thing?
Cherikee Red's gotta take the cake for most racist soda in my neck of the woods. It's good stuff though, and hails from out east a ways, but I still consider it pretty regional.
Very regional is a bottling company about 20 mins from where I live called Natrona Bottling, which still sells pop in glass pop-top bottles. The flavors are heavy, and the carbonation isn't a mechanical process like most are now. They actually bought old carbonating machines to do things old school. Pricey, but love it.
Tried and true Faygo is still big here... Not just for the Juggalo either. Love the black cherry.
I love micro-brew beers, but I've found almost every place making its own beer makes its own root beer too, and so I also love to sample the thick syrupy micro-root beers around here too. I'll even buy a growler, but that stuff can make you sick if you hit it too hard. It's a diabetic nightmare.
