Active Dry Yeast

The Activation Process:

To activate active dry yeast, it's crucial to follow the proper steps. Begin by sprinkling the yeast over water heated to 105° to 115° F and allow it to sit for approximately five minutes.

During this time, the yeast should start foaming, indicating that it is useable. If you don't see any activity, it's likely that the yeast has gone stale and should be discarded.

In keeping with the Keldons Cookery mantra; 'When in doubt, throw it out' :).

Longevity:

In the Pantry - Before opening, active dry yeast can be stored in a cool, dry place such as a pantry. The original unopened package is designed to keep the yeast dormant by protecting it from moisture and air. Make sure the storage area is away from any sources of heat or humidity.

Active dry yeast can last up to 2 years when stored unopened in a cupboard. The exact shelf life can depend on the brand and the storage conditions, but generally, yeast kept in a cool, dry place remains viable until the printed expiration date.

After Opening - Once the package is opened, the remaining yeast should be kept in an airtight container. Transfer it to a jar or a resealable plastic bag to keep air and moisture out. It’s also helpful to store it in the refrigerator after opening, the cooler temperatures help preserve its activity.

If refrigerated, active dry yeast can typically last from 4 to 6 months. It's important to keep it sealed tightly when not in use. Each time you use the yeast, minimize its exposure to air and moisture by keeping it sealed as much as possible.

In the Freezer - Active dry yeast can also be stored in the freezer to extend its shelf life. When frozen, the yeast can last for up to 1 year beyond its initial expiration date. To freeze, make sure the yeast is in an airtight container or a heavy-duty freezer bag to prevent freezer burn.

There is no need to thaw the yeast before use, you can measure out the necessary amount directly and return it to the freezer. The cold does not kill the yeast, it merely keeps it dormant.
