Bacteria in your DIY CO2? Try this:

Aspirin.

I knew the stench of bacteria the instant I smelled it. IMO, there's no point in trying to use proper aseptic technique in the kitchen to keep bacteria out of the brew 'cause it just ain't going to happen. Instead, I add an antibiotic that everyone has in their house. Aspirin. It's fine for yeast, but it slows down some bacteria and kills others. I had no clue whether it would work for whichever bacteria species take over yeast cultures, but I tried it, and it works. My yeast are cooking away, and the stench has never returned.

I use three to six 325 mg tablets per two liter bottle.

Aspirin isn't an antibiotic. It's a nonsteroidal anti-inflammatory. Not knowing much about DIY CO2 methods, I can't comment on why it would make it not smell, but it's not a specific antibiotic agent.

Agree.... And why is your DIY CO2 smelling septic?
Yeast & alcohol creates a very unpleasant environment for bacteria. Are you one of those that put gelatin in the mixture?

Trust me on this one. I've read the research papers. Aspirin is bacteriostatic to some bacteria species and bacteriocidal to others. Aspirin enhances the pathogenicity of still other species of bacteria. Or don't trust me, I can dig up references. There are thousands and thousands of chemicals out there that kill bacteria that your doctor will never prescribe to you as an antibiotic. And yes, aspirin is a NSAID. It also inhibits NF-kappaB signaling, a secondary mechanism that contributes to its anti-inflammatory effects but does many, many other things in systems from your immune system to your brain.

No, I don't use gelatin, but I do put other nutrients in for the yeast besides sugar via molasses. This indubitably makes it a more hospitable environment for bacteria, but also for yeast.

Edit: Other common antibiotics include most spices used in Indian cooking, for those curious.

try honey next time too. It's sugar and it has antibiotic properties. Did you know honey never spoils?
