I’m basically excluding Coca-cola, Pepsi, and whatever you feel are major brands. You don’t have to exclude them, but I have a fondness for flavors outside the big brands.
I highly recommend:
Faygo Candy Apple - really my top recommendation. I am a Michigander, but hasn’t Faygo gone nation-wide now? If so, pick this up. 99 cents for a 2-liter and it is great.
Faygo Cotton Candy - the most recent addition from Faygo to have gone permanent. I thought it would be sickeningly sweet, but they did a great job with this one. Highly recommended.
Early 1970s Baltimore (possibly a larger region) had Drink Me Pop; two dozen (or so) different flavors. They had a pineapple soda that would knock you on yer ass. Plus, Birch Beer, Cream Soda, Root Beer, something blue I don’t remember the flavor of, all kinds of pop. You’d have the happiest rotten teeth in the whole Mid-Atlantic region. Sadly, long gone.
Mountain Dew is available with real sugar again, but I don’t think they use the red pepper* anymore.
*I can’t find a cite for red pepper use, but I swear on my mother’s eyes – in the late '60s, MD had red pepper in it. You don’t forget something like that when you’re eight.
My favourite thirst quenchers on a hot day are from Bundaberg. I know you can get at least one flavour from them in America, their Ginger Beer, but maybe the rest are around too. The flavours themselves aren’t all that exotic, but they really hit the spot. My favourite is Apple Cider, though I do swap it with some of the others for variety’s sake.
I used to love Sioux City Sarsaparilla but haven’t seen it since the late '70s. Just found it at Cracker Barrel, but at $1.95/bottle, I’m stalling on purchase.
In the Chicago area, you can definitely find bottles of it. It’s not ubiquitous, but not unusual. ETA: Well, this article does call it ubiquitous in Chicago, so maybe it’s even more popular than I thought.
Fentiman’s Curiosity Cola. It’s kind of hard to find, a bit pricey, they sell it here in the natural foods aisle, for some reason. Fentiman’s has a couple other wonderful flavors, like Rose Lemonade . Curiosity Cola tastes just like I think Coca-Cola must have tasted in the early days, very Coke-ish, not too sweet, with a medicinal tang. Love it!..Also, bottled by the Coca-Cola plant in India, is Thumz Up, also a cola type. Sold in the India imports store in beat up thick glass bottles.
It never fails to annoy me when someone makes a big deal out of insisting on ginger beer instead of ginger ale, because the beer is stronger. I’ve never found a ginger drink more intense than red-cap Blenheim.
I used to like Brainwash, but it got really hard to find.
I don’t know about soda … don’t really drink it often but I will say that Pellegrino Blood Orange (sparkling water w/juice) is pretty tasty … especially with a shot of Captain Morgan spiced rum.
