Yes – if it’s relatively fresh grain spawn then you can store it in the fridge for at least 2 months in good condition. If you are quick, clean and careful when opening the bag, then you can re-seal it and put the bag in the fridge for next time. Be sure to wipe the bag down with alcohol before using if it has been in the fridge to make sure it’s clean before tipping the spawn out over your coffee mix.
