Best Before / Use By Date

Best Before/Use By/Expiration Date

Our yeast products specify a Use By date. This is the date at which we recommend the yeast is used by, as it represents a point at which the yeast is still viable but starting to decline in quality. We strongly encourage brewers to use the yeast prior to the Use By date. For homebrew pouches nearing the Use By date, we recommend making a yeast starter for best results. 

We are continuing to assess shelf life of our yeast products and make adjustments to the Use By windows based on the data.
