Months at least, if refrigerated.

Refrigeration will slow or halt growth.

Max of 6 months to hold jar until it starts to decline.

i just put some shiitake grain spawn onto sawdust and bran. the shiitake had been in my fridge around 8 months. it is in the "leap-off" phase right now and growing like crazy, as good as my king mushroom grain spawn or better on the same substrate and the kings are less than a month old.

like Migraine says,

one problem i did have on one of my shiitake grain spawn in the fridge was, it started to fruit right in the fridge from the grain. very weird in a way.

I have had grain jars last 16 months when refrigerated..... really depends on how clean it is.

Yeah, they will last a long time in the fridge. Though every time I keep colonized jars in the fridge they start to fruit invitro after about 3 months...

Depends on the species, generation of the spawn used and the conditions inside your fridge, the more fluctuations in the internal temp the shorter the shelf life will be.

It is generally accepted that a colonized substrate will last about 6 months in the fridge.  Try keep the temperature around 2-4 degC.
