Over at Hack Pittsburgh, we are running an experiment to try and brew an open-source version of the highly caffeinated Club Mate soda drink. The first version uses Chai Mate tea mix, cane sugar, and caffeine powder, but already we have suggestions to improve the next batch.

It’s actually pretty easy to make soda, even if you don’t have fancy equipment like a soda keg and CO2 tank. If you are interested in trying it out, Becky has you covered with the DIY soda episode of the CRAFT Video. Already have a favorite recipe? Share it with us in the comments!
