active yeast not activating

I have tried on several occasions to activate ADY. Each time I tested the temp of the water to make sure it was not too hot.

I put some ADY into warm water and add some sugar. Then I wait maybe 10 minutes.

Now matter which brand of ADY I'm using, I can never get the yeast to activate. It just floats on the surface and does NOT foam or do anything.

These are all fresh packages. The one I tried today had an expiration date of 4/2020. Other packages I've tried have also been reasonably new (far from expired).

Since I have tried Red Star and Fleischman's brands, I can only conclude that it is ME who is doing something wrong.

Does anyone have any suggestions as to what I might be doing wrong, or maybe do it differently?

Hi Tory I've read that the Chlorine content in the tap water in some communities is high enough to stop ADY from working properly. I think the suggestion is to leave the water in an open container for 24 hrs, or to boil it and let it cool.

Good luck,

Great suggestion Todd. For the sake of troubleshooting, it might be worth buying bottled water to see if there's a difference.

What are the amounts of water and yeast you're using Tory?

Todd and Raj's suggestions are spot on. However, you posted "I put some ADY into warm water and add some sugar. Then I wait maybe 10 minutes."

This might be a stupid question but do you actually whisk the mixture for maybe 20 secs until you have a cloudy or milky-looking fluid?

You shouldn't need any sugar to activate it. It should bubble after stiring it vigorously for about 30 seconds in 3-4 ounces of water and smell well like yeast. How much water are you using and how much yeast? Recipes can vary, but you only need roughly 1 level teaspoon of ADY in that 3-4 ounces of warm water for 1lb of flour.If you are not doing a cold ferment in the fridge for 24-72 hours and making dough that day then try 2 teaspoons/lb at room temp for about 2 hours. The yeast will feed once you mix it in the flour mixture. Save any unused yeast in a sealed container in the fridge.
