How long can I store Imperial Yeast Pitch Right pouches prior to use?

We recommend using the freshest possible yeast and we back our yeast for 4 months from the manufacture date on the front of the pouch. If you find yourself with a pouch past its expiration date, we recommend making a starter. This increase is the result of a recent extensive study conducted with multiple strains over the course of several months. We found that the impact on viability was negligible for all our strains at four months from the printed manufacture date. This applied retroactively to all yeast in the marketplace. Expect to see the same reliable, healthy and happy fermentations that you have come to expect from Imperial Yeast.
