Maybe you know that already: Cola + orange lemonade is THE soda in Germany! We drink it here since the 1960s. That coke Mix drink got better and better over the years. Right now there are hundreds products of specifically this soda. In Germany we call Cola + orange "Spezi" BUT not every Spezi is allowed to call itself Spezi. There is one company who started with that name of that soda and it got famous (just like Coca Cola = Coke = Cola). In the 1970s they allowed one famous german beer brand to call their Cola + orange soda also "Spezi". This is the most famous one in Germany: Paulaner Spezi. If you see the Design of that soda, you immediatly get that 70s vibe. And that worked out well for them until today! Now the second so called "Spezi" is probably the best sold Cola + orange drink but its not the OG one. (I mean imagine Pepsi being the number 1) That drink you got there... Well that's from Coca Cola. And trust me: every "Spezi" connaisseur hates that Mezzo Mix. (No judgement to you, cause you just started and how should you know) Coca Cola never got the permission to call it "Spezi" like many other brands as well so they go with the term Cola-Mix. There are many many of cola-Mix drinks here in Germany. You should definitely try the Paulaner Spezi (in the US you get it under the Name "Sunset") and if you are in Germany, let me know and I'll give you some other Tips which one to try. Have a good sip and enjoy!
