I know Afri Kola (not much, only have had it a couple of times in Germany) and Fritz Kola (moree common in other countries, delicious, also other flavours, orange and apple are very very good).
Orangina was always a treat on holidays in France.
Just try different caffeinated sodas.
Like ChariTea, Club-Mate, MioMio etc…
Club Mate is exquisite
Kofola (from Czechia)
Kofola is god tier, originally Czechoslovak but sold in Central/Eastern Europe. It’s more herbal so it’s a matter of taste like with everything but many people seem to enjoy that.
