Hmm, but we aerate our beer; we got oxygen there. dunno... I know that some micro-brewers will also venture into Root Beer & Creme Soda which i think have the most unique customizable tastes amongst the soda/pops. I think I'll leave the root out of my beverage creations. Interesting to know the process though I guess.seven77 said:But seriously, I thought yeast only made alcohol from sugars in the absense of oxygen. For example: there is yeast in bread, but you don't get drunk from eating it, ya know?
