Salting: ~2 weeks

Seasoning: ~2 weeks

Drying: 3 days

Maturing: recommended 3-12 months (or more!)


Wide mouth Glass jar, crock or other food-safe vessel.

Toothpick or skewer

Ziplock bag

Pickle weights approximately 2-3x weight of ume (see options in recipe)

Drying mats or dehydrator



Ripe ume fruit (measure the weight with a scale to calculate your salt) Sea salt (8-10% of the total weight of ume)

Splash of alcohol (vodka, gin, etc)

Fresh, red shiso leaves (needed by ~week 3)


Rinse ume fruits and pat dry. Place the ume in a ziplock or silicone bag and pour the alcohol over to disinfect. (This reduces the chance of mold). Using a toothpick or skewer, remove the small stems/nodes on the fruit.

Sprinkle a light layer of salt at the bottom of your chosen vessel. Place a layer of ume and cover with another layer of salt. Repeat this process to make layers of ume and salt until all is used up!

Place a heavy weight on top of the last layer. The weight should be 2-3x the weight of the plums. You can use a combination of pickle weights, pie weights, ziplock bag full of lots of salt, canned goods and/or a heavy jar full of water! Get creative!

Store out of direct sunlight for ~2 weeks. Check everyday the first week to make sure it’s drawing out liquid (aka umesu vinegar). Add more weight if necessary. It needs to draw out enough liquid to completely cover the ume by the first week or you risk mold.


After ~2 weeks, prepare fresh red shiso leaves by sprinkling a little sea salt on them and massaging them gently to wilt. Squeeze out the moisture created. Pour a tablespoon of umesu (pickling liquid) over the leaves to season and draw out their color. Add to the jar of umeboshi below the weights, and leave to ferment for another 2 weeks.


Check the weather for 3 consecutive hot, sunny days to sun-dry the umeboshi, or use an electric dehydrator for ~1 day.

To sun-dry, remove the umeboshi from the jar and place onto a drying tray, bamboo/straw mat or another similar type of mat that allows airflow, to dry. Make sure to leave space in between the fruits. Squeeze the liquid out of the shiso leaves and spread the leaves out on the tray to dry too. Bring in the tray at night, returning the plums to the umesu brine and then repeat for 3 days total.

After sun-drying, transfer the ume back into clean jars (or your original vessel) and distribute some of their brine (umesu aka plum vinegar) for long-term storage. They no longer not need to be completely submerged, in fact some recipes keep the umesu separate from the umeboshi from this point forward. However, we recommend keeping them in a little brine for flavor. Store at room temperature. Bottle any excess umesu and use in dressings and marinades!


We recommend aging umeboshi for another few months at room temperature. For a refined umeboshi, age for 1 to 3 years. Umeboshi does not need to be refrigerated long term.
