Why didn't the colonial powers teach these people how to brew beer?

So I am now in Gabon, ex french colony, on the west side of Africa. Been a hectic few weeks of travel but it has beed fun all the same.

One issue however is the distinct lack of any brewing skill when it comes to beer. Now I expecteded it to be some form of fizzy pop....however did they brew it in a muddy river. It is worse than Peruvian beer and that is saying something.

The french can brew some beer so why on earth could they not pass this bloody knowledge on? Its a disgrace.

TBH I am more disgusted that the Brits could do no better in Nigeria!!
