Our relishes have been made to the highest food safety standards and, as a food product category, low Ph products such as relishes, are very low risk. We put a ‘best before’ date of 12 months after manufacture if kept in a cool (less than 16 degrees C), dark place unopened on our relishes which is very, very safe. When they are opened, they need to be popped into the fridge at 5 degrees Celsius where they can be safely kept for a month in a clean jar.
