You can use expired yeast provided that some of it is still active. Yeast that’s past it’s prime will take longer to grow and raise the dough, so only use it with breads that are made without eggs are a lot of sugar (those bread recipes need a pretty powerful proof that weak yeast can’t provide).
How can you tell if yeast is good or bad?
There’s an Easy Way to Check
Proof your yeast to find out if it’s still active by adding 1 teaspoon of sugar and 2 1/4 teaspoons of yeast (one envelope) to 1/4 cup of warm water. Then, wait 10 minutes. If the mixture bubbles and develops a yeasty aroma, the yeast is still good.

The cells contain no water; hence, there’s nothing to cause them to rupture when stored at temperatures below that at which water freezes.
How do you store instant dry yeast?
Like active dry yeast, instant yeast has a shelf life of two years and performs best when it’s kept away from heat and moisture. After it’s been opened, you’ll need to seal it in an airtight container and store it in the fridge or freezer.
Can Mason jars store yeast?
You can also transfer the yeast to a glass jar with a tight-fitting lid. Don’t forget to label! Before storing, label the bag, container, or jar with the date it was opened or the use-by date (four months out if you’re storing it in the refrigerator or six months out if you’re storing it in the freezer).
Which yeast has longest shelf life?
Freeze-drying puts the yeast in a sort of hibernation so it lasts much longer. Unopened, packets of instant and active dry yeast should last 2 years. Red Star Yeast, for example, puts the “Best If Used By Date” for their dry yeast at two years from the date the yeast was packaged.
