Bread yeast is a living organism. Over time, it loses its potency and ability to make dough rise. Yeast packaging has an expiration date and it is best to use it prior to this date. If dough is made with expired yeast, it is possible to rescue the slow rising dough by using a new package of yeast.

What is the difference between instant yeast and active dry yeast?

Newly purchased yeast (with good purchase-by date), can be stored in a cool location (pantry or cabinet), refrigerated, or frozen for up to two years. Once the yeast is opened, it’s best kept in the refrigerator to use within four months, and six months – if kept in the freezer.

How do you revive old yeast?

If your yeast is “dead” or “inactive” then you will need to get new yeast—there is no way to revive it or liven it up again once it goes bad. Dry yeast can last up to 12 months, but there is no guarantee. We recommend storing it in the refrigerator, especially after it is opened.

What do I do if my yeast isn’t foaming?

If your recipe doesn’t call for sugar, add a small amount (1/8 teaspoon will do it) to the proofing mixture to give the yeast something to feed on. If the mixture isn’t bubbly, the yeast is no longer good. Dump out your mix, and start with fresh yeast. Unfortunately, there’s no way to revive old yeast.

What happens if you use active yeast instead of instant?
