OpenCola, Version 1.0. In yet another attempt to suck up to the naturally fanatical geek community, OpenCola comes with a stupid Perl poem on the can, and a recipe for homemade cola that they are pretending makes OpenCola the first consumer product released under the GPL. Not quite, of course: the recipe is not the actual recipe for the OpenCola product (to be expected given the nature of mass soda production).
Another homemade cola recipe. (I dunno, I think I'd rather try the more specific syrup formula mentioned above. Vanilla, cinnamon, lime and sugar? At least this one includes extract of cola, though the 15lbs sugar : 1gal water ratio is... well, probably realistic...
