Buy European

@Sunshine some examples from Germany are

https://en.wikipedia.org/wiki/Club/_Cola
https://en.wikipedia.org/wiki/Sinalco

Finland has (vappu)sima, but it is only produced and sold around 1st of May. Or you can make your own at home with white sugar, molasses, lemon and baking yeast.

Brit here.

Chinotto is goddamn awesome. Pls export more.

Norway has Solo

Like an orange flavored soda, apparently it predates Fanta by a few years

Litteraly translates to "Thirst extinguisher", which is also a general german term.

From Germany, i would recommend https://en.m.wikipedia.org/wiki/Club-Mate

Julmust/Påskmust from Sweden. Soda thats derived from malt and hops. Only availible around jul(christmas) and påsk(easter) and stands for half of the total soda consumption around that period.

Also Cedevita from Croatia. Vitamin enriched powder, originally in orange flavour. When mixed with water it's like a soda

Vitamalz

I like Estonian Kelluke, a local carbonated lemonade. Probably mostly meant for kids, but hey...

It's a must

Japan has Pocari Sweat inspired by a doctor drinking IV fluid.

I am Swiss and Scottish, we have Rivella and Irn Bru respectively. In the UK we also have a drink called Lucozade which was interestingly designed as a medicine but was saved from liquidation (no pun intended) by the rave scene as they needed something that would keep you hydrated, not get you too drunk and helped with comedowns.

We have Irn Bru and it's made from girders.

It also has some of the most amazing Adverts

Surprised that Club-Mate hasn't been mentioned yet, I'm not German so I didn't discover it till more recently but I quite like it, not as sugary as other drinks

Dandelion and Burdock, originating in the British Isles. Traditionally made from fermented dandelion, and burdock roots.

I think it tastes sort of similar to root beer.

Australia has bundaberg ginger beer which is good shit. Nice and spicy.

Uk. Dandelion and Burdock.

It's closest equivalent would be root beer, but it's quite distinct from that.

Sadly, almost all UK soft drinks taste like shit now because of the Sugar Tax, where they've been reformulated to use more artificial sweeteners to avoid being taxed more heavily.

Water from the tap. Healthier, cheaper, local and better for the environment(no shipping)

In Austria we have Almdudler

A Czech friend likes Kofola, a cola created in Communist Czechoslovakia, when Coca Cola wasn't available there. Nowadays, Coca Cola is available, but Kofola still reigns supreme — when I visited her, I discovered that the majority of pubs that I visited had Kofola as their "house cola" on the tap. Coca Cola was often available, but in comparatively expensive bottles, because it was not the default

Years ago I had some imported drink called Jul Must. Haven't seen it since. Came from somewhere Scandinavian. Weird flavor, probably an acquired taste, and I WANT MORE!

Poland has oranżada, soft drink of orange taste. Its also available in a powder form. Also this photo from Wikipedia goes hard:

Trocadero, a soda with orange and apple flavour from Sweden. They released a zero sugar version which is now called Trocazero.

Rivella, a Swiss soda produced from milk whey.

And nothing special about the Migros Ice Tea, it is an Ice tea, but it is the best tasting one in the world and a casus belli for war in Switzerland (yeah, the only reason we have to fight).

Birch beer. It's like root beer but a bit of a different taste.

We have Orangina here in France, it's an orange soda with pulp and very horny ads for some reason

[Slavs trampling each other in order to be the first one to yell "kvass"]

I love chinotto so much. They used to sell the San Pellegrino one here in the UK, but it got discontinued.

It's great. Like a Campari and soda without the booze.

San pellegrino makes chinnoto as well, had it at a really good thin crust pizza place called Emilio Finnati's

Sadly they don't often have it in stock anymore, but I've found a bunch of it from various makers now that i know it exists.

Is not for everyone for sure but it's absolutely worth trying just to see if you are one of the people that find it really great.

I think anyone who likes or isnt bothered by the bitterness marmalade would be likely to enjoy this

Beer is everywhere. It's one of the most "local" products pretty much everywhere in the world.

I adore chinotto its absolutely delicious

(Not european) South Africa: granadilla twist/lemon twist - both just a passion fruit/lemon flavoured soda but they're delicious

UK: Irn Bru, a Scottish drink with a secret recipe that tastes like flavour (honourable mention for Iron Brew, a South African drink that is also delicious but does not taste remotely like Irn Bru)

The Austrians have Almdudler, the Suisse have Rivella and the French have Orangina. I am chugging that stuff whenever I can get my hands on it.

Then there's Japan, with too many to list. Calpis is one of my favourites.

Kofola from the Czech Republic: https://en.wikipedia.org/wiki/Kofola
