I don't know where you were in Africa but I used to live in Kenya and the local beer was excellent. My favorite was Tusker...
I was in northern Nigeria for more than a month once. The group I was with and towns we were in were not the setting to explore beer options. If beer was available there I have no idea.
We stopped in Amsterdam for a day on the way back to the US and the few who were not teetotalers enjoyed that Heineken thoroughly. It didn’t taste skunked over there like the US bottles always do.
