Fast rise yeast or regular yeast for CO2?

[Jag1980]

Does it matter what type of yeast to use?
What would the difference be compared to fast rise yeast and regular yeast found in the grocery stores?

I would just use regular yeast because it's proven and easier to find in grocery stores. I don't mind having to wait a couple of hours to get my CO2 going.

I've tried the regular yeast and it take soooooooooooo long to start and I am very un patient. I can get fast rise yeast in the store so I was wondering if there is any difference.

I don't have a good answer for that, but my guess would be regular, it would be interesting to quantify the difference.

Did you hydrate the yeast before adding it into the sugar water solution?

I read somewhere that fast rise yeast doesn't really work with DIY CO2. Something about temperatures.

Before, I used regular baking yeast. Nowadays, I use champagne/wine yeast that I bought from eBay. Lasts longer (higher alcohol tolerance) and stays active in lower temps. But it still take a few hours to start up like regular yeast and it requires a pinch of baking soda as buffer.

rapid rise yeast will give you that big burst of co2 but that will be it. A big burst, I use regular yeast and never had a problem. Mine last 4wks easily, you might get faster yeast with rapid rise but get ready to be mixing every 2-3 days. That's just my thinking anyhow. go with the regular or champange yeast.

I think I'm going to have to try the champagne yeast, sugar is starting to get expensive..

Do I use the same mixture as bread yeast?
1/2 tsp yeast, 2 cups sugar, 3/4 water

I put a 1/4 tsp yeast but that's why mine lasts so long. And a pinch or two of baking soda. But other than those, same recipe.

I suggest 1 part baking soda 4-3 parts sugar 1/2 part yeast and 7 parts water... mine lasted for 1 month already....

umm we are supplying CO2 not making muffins. I'm using regular yeast, and sugar. you can use other sweeteners as well, but keep in mind artificial may kill the yeast.
