Wine yeast

I have heard that wine yeast lasts longer than baking yeast when used in DIY co2. Does anyone have experience with this? What type is best suited for this application?

Champagne yeast has even more life.

The reason is alcohol tolerance. Bakers yeast has a low alcohol tolerance, whereas wine and champagne yeast can still reproduce in the presence of high amount of alcohol.

The longer the yeast is in the sugar water, the more alcohol is building up in the bottle.

Thanks for the reply. I already had an understanding of this, however. Have you used champagne yeast for co2 production? What strain did you use?

I brew hard cider with champagne yeast, it makes a lot of co2, my airlock is always bubbling at a rapid pace. I don't use DIY co2 in aquarium though.

Also, your fermentation will start quickly if you re-use the yeast several times before completely clean out your reactor vessel. The first go-around, the yeast acclimates to the alcohol. When the sugar is spent pour off all the liquid but leave behind the yeast and sludge on the bottom. Put fresh fermentable liquid on top for round two. Plus, you don't have to buy more yeast!

Great info there p. Welcome to TPT, btw. Do you use this method yourself? If so, I would be interested in hearing more about it. Specifically, what type of yeast used and where to get it. Do you start it the same way as baker's yeast?
