This article says that both Ethiopia and Yemen claim to have discovered coffee. The Ethiopian claim is that it was discovered and brewed in Ethiopia and the Yemeni claim is that Ethiopians discovered but Yemenis brewed it. I like the Ethiopian story better but it either have no conclusive evidence

What’s your source. Ethiopians will tell you up and down that they discovered and brewed coffee first

I just tried Newpipe to double check, it works fine for me
