I am not really a fan of liquor, but I do like the idea of having skills which are universally valuable.

If you air dropped me into a random village in Africa I doubt I could 'code for cassava' but I could almost certainly make a living if I knew how to set up a basic pot still and safely create booze.

You could sanitize and disinfect with that alcohol! You could also make extracts of any plants nearby that were useful. Whiskey and vanilla beans are sufficient to make vanilla extract!

Sub saharan africa already has a very large informal distilling network (especially of bananas), a niche largely reserved for women in many regions (not sure for what the reason is for that exactly).
