I was driving and found myself craving some caffeinated soda. Since coca and Dr pepper are now off limits I just downed an espresso and got a (European) ice tea, but I'm wondering if there are actual alternatives
Almost every country has tons of domestic soda brands, though most of them are only available locally/regionally and some of them are probably USA-owned.
In Germany there's Fritz Cola, Afri-Cola, Sinalco, Mio-Mio, Club Mate, Bionade, Paulaner Spezi and many more.
Yeah in France we have tons of "regional" colas but outside of Brittany (Breizh cola) and Corsica (Corsica cola) you're not finding them in a gas station
Gas stations are definitely difficult, many of them just don't have the shelf space for 5 different cola brands, and if you can only pick one it's hard to justify anything but coca cola from the perspective of the gas station owner ...
