While utilizing instant yeast, the storage preparation and shelf life will be quite comparable to active dry yeast. While your instant yeast can keep for roughly two years if kept sealed, once opened, you must take steps to prevent deterioration.

Exposure to air is your instant yeast’s enemy when it comes to remaining fresh.

Exposure may drastically reduce its longevity, so keep it in a sealed container. A glass mason jar with a tight-fitting lid is an excellent storage container for instant yeast, keeping it fresh for up to four months in the fridge and six months in the freezer.
