When following the recommended storage instructions by keeping them unopened at a temperature below 20°C, 12-24 months can be guaranteed.
If you keep them unopened in the fridge or freezer at a temperature below 5°C a much longer life could be obtained.
However once opened their shelf life will be reduced. We recommend that you then store them in a sealed container in the fridge to preserve the nuts and stop them absorbing moisture from the atmosphere.
