Liquid yeast test

[Eharry]

I received my liquid yeast at room temperature after shipping. Is there any way to test it to see if it's still good?

Many people on HomeBrewTalk would suggest that you need to use a starter to build up the number of cells before pitching the yeast. Making that starter would let you see if the yeast will propagate. Once propagated you can refrigerate the starter and keep it for a few days before pitching if necessary.
