Switching out DIY CO2

Does anybody just pour the sugar water off the yeast, add new sugar water when they need to change the bottle? Will this work as well as starting a new bottle altogether? I'm wondering because I'm going to start making home-made bread and want to use as little yeast as possible with the fish tanks. Thanks!

no, the reason you'll need to change out the water is because the alcohol that the yeast creates will eventually kill all of the yeast off, so you'll need to put in new yeast. the sludge that gathers at the bottom can be reused though, so don't like scrub out the bottom, just pour out and refill. i dont think you need all that much yeast in the sugar-water to start producing CO2 anyway.

if you can make homemade bread though, that is REALLY cool.

I'm thinking of re-doing the sugar water more frequently than the 2 week interval I've seen recommended for refreshing the whole yeast mixture; and starting a new solution from scratch less frequently, like every 4-6 weeks. We'll see how my bubble production does.

A jar of bread yeast is only supposed to be good for 6 months after it's opened. Chances are that unless you're baking bread *really* often, you won't go through that quantity in that time, so a 1/4 tsp every so often to recharge your CO2 mixture probably won't hurt your baking plans.

Just thinking about it (this is a debate I've been having internally since I started my DIY and my biochemist/hobby brewer husband suggested feeding the yeast colony frequently), if you dump off the liquid (alcohol and sugar water) while the CO2 is still bubbling merrily away, clearly there are live happy yeast in there doing their thing, so with a fresh supply of food and a decrease in toxic waste, surely they will reproduce and regenerate quickly? Sourdough sponges keep for years if fed regularly, after all.

I keep my yeast in the freezer and have had it for over 6 months... still works fine!

Indeed, it does. When my yeast starts bubbling slowly, I dump most of the solution off (leave about 1/4 of it), add new sugar and water, and connect it back up. It starts faster than starting from new yeast too.

I'm considering getting some super yeast that can ferment up to 20% ABV. The only problem is that they seem to also be super fast - 20% in 5 days. Perhaps Champagne yeast is a better option.

Ditto.

That is what I do. Tara Nyberg recommends doing this as well.

Thanks, that's what I'll start to do then!
