Reusing harvested trub/yeast

[hoppyscotty]

Made an IPA with Berdant yeast about 4 months ago and harvested the trub and put in a sterilised mason jar. Thinking about using it this weekend but not quite sure what to do to prepare it. I’ve watched ten different YouTube videos and got ten different answers.
I’m assuming I decant off the liquid from the top and can make a starter with the trub?

thanks

If you got ten different answers from You Tube you'll probably get ten more here and end up just as confused.

I would smell it before doing anything. I've had yeasts go off even when kept in the fridge in sanitised containers. If it smells OK then I would pour off the liquid and make a starter with the remainder.

Personally I wouldn't be using it, the jar its been kept in looks pretty manky and not even filled to the top.
Is it really worth taking the risk?

I wouldn't take the risk when new yeast is a few quid an guaranteed to be sound.

I re-use yeast a lot, but say no to this one, mate.
