How do you store it ? Storage question

I've made this recipe for years and YES it does get better with age (though delicious from day 1).
Storage options;
Water bath sterilize, then store sealed up to two years.
Once you open a sealed jar, store in fridge up to 1 year.
Or, store in fridge directly after making.
I've heard of storing jams and chutneys in the freezer, but I've not yet tried it.
