How long does miso paste last?

Inspired by the miso paste post below, I rooted (sorry) around the fridge and found a tub that's been sitting there since last winter. Can I still use it? And while we're at it, what are your favorite quickie recipes? I add various veggies and seaweed and a little tofu.

  1. properly sealed
    6 mo. to a year

    tho' some preserve much, much longer

    Andoh suggests in Washoku that shiro miso is best used within 6 months otherwise one faces degradation of nuances

    I've kept shiro miso a year in the fridge no problemo

    1. It should last for a very long time. Months are just a drop in the bucket when it comes to the lifespan of miso.

      1. I was wondering this myself. I think I've had my container for years. I used some about 6 months ago and it was fine -- no one died. And I didn't notice any nuanced loss.

        I like that -- very Zen. :-)

          It's been almost two years--has anyone died yet?

        2. I keep mine in the fridge - Maybe a year now and it's fine. Miso is already fermented but, keep in the fridge, sealed and it will last eons.

          1. It will last longer than your fridge.

            1. I am still using miso that's at least 2 years old...and it's great. It almost tastes better now than when I bought it.
              Kept in the fridge, in packaging excluding air. A little goes a long way and I evidently bought too big a package for my needs..but in the end, no regrets.

              1. Had to wake up a long dead thread but...my shiro miso changed color (darker) is it still okay to use?

                    A second to that "yes". Properly sealed & kept in the fridge, Miso is nearly invincible.

                  2. I have the AKA Red Miso Paste in a plastic tub in the refrigerator. It's nine years old and still exactly like when I bought it. I hadn't noticed the tub in the back of my fridge for about a year and opened it, expecting it to be moldy or something. Nope. Then I moved twice. Threw away everything in the fridge each move except the miso because I wanted to see how long it would last. I try it about once every year. I just tried it today. Perfectly fine. Nine years old. Where does the time go? Pretty soon I'll be sending it off to college.
