Umeboshi
Store finished umeboshi in a sealed jar or bag so they do not dry out. Keep the ume vinegar from pickling for cooking.
Umeshu
Umeshu is preserved in alcohol, so it has no best-before date and does not go mouldy. For ageing beyond a year, take the fruit out at about one year: see when umeshu is ready.
Ume syrup
When the sugar has dissolved, take out the fruit and keep the syrup in the fridge for about a month. For longer storage, heat it to 80°C or more in a non-aluminium pan, let it cool and refrigerate it in a clean bottle. If it ferments, see ume syrup fermenting.
