I just wanted to experiment homebrewing some Soda for a kick. I found a few pages online that say the process is quite similar to homebrewing Beer, but somewhat easier and faster. As far as I know, I could heat some water, mix yeast with any kind "juice", let it rest for a day and get something of a Soda.
My question is, what safety measures should I take into consideration? Should I avoid using some kind of product? Are there any chemicals that could be harmful when combined with yeast? For instance, if I wanted to experiment carbonating a "Crystal Light" instead of using real Juice, could that have unforeseen consequences?
