No bubbles from co2 mixture

It's been 24 hrs and I have only seen bubbles twice. I've mixed several batches that have worked well...until now. The only difference is the brand of sugar. Can that really be the problem?

I don't think so. As long it is 100% granulated sugar it should be fine. Make sure your yeast is still alive and that the water was not hot or cold, it should be a bit warm and should be tested on your wrist.

Well, the yeast is far from being expired. It's in a jar kept in the fridge. I let it return to room temperature also. I test the water to be 25c. Maybe it should be a tad warmer?
How does one know if yeast is alive?

Well I think your water was too cold, you need the water to be a minimum 90*F and no hotter than 104*F. This is how you get yeast active when you bake bread or other things that need to rise! And that is also how you proof your yeast before you add it to your bread

Put a half teaspoon yeast in about half a cup of warm water. Add 1 tablespoon sugar and stir. That will proof your yeast and prove it is viable or not. If it bubbles and smells, add it to the CO2 bottle. If it doesn't bubble, your yeast died.

Hmm, I'll dump this batch tomorrow then. Thanks...

Should the water in the bottle also be warm or can it be room temp?
Thanks!
