It has been a number of years since I read it, but in Charlie Papazian's Microbrewed Adventures he has a story about drinking some sorghum-based drink while in Africa. Apparently you drink it while it is still fermenting. If I recall correctly, at the end of each of his stories he has a recipe that approximates the beer he as talking about. I'll see if I can dig out the book tonight and find a recipe.
From going to Disney's Animal Kingdom Park, I was specifically looking for African beers to try and they were offering Tusker from Kenya and Windhoek Lager from Namibia. I believe they are both German-style lagers without the addition of anything unusual. They have both been brewed in Africa since the 1920's or so. I coincidentally stumbled upon them again a few days ago while looking for a Kilkenny Irish Ale clone recipe. I wasn't aware they are all owned, along with Guinness and a number of others, by Diageo.
