There is no need to keep your miso soup pastes in the fridge. You can store your product in a grocery cupboard, in as cool a place as is practical. The Japanese boast that, apart from the colour, miso paste lasts a hundred years! But to be careful and comply with UK regulations, there is a best before date located on the box.

Regarding our organic cooking pastes, we recommend that once opened, you keep these in the fridge and use within 3 months. As above, miso can darken as it is exposed to air and over time.

If you see any mould growing on top of the miso, we advise that you throw it away, although we have heard about people who simply scoop off the mould and carry on and we praise the brave who do! As this is an unpasteurised miso, we recommend that you store the miso in the fridge once you have bought it from Miso Tasty!
