I saved some of the trub from the bottom of a primary in which I used Safale 05 to ferment a 1.045 gravity ale. I packaged the slurry in two sanitized bottles, capped them and refrigerated them.
Will I be able to re-use this yeast and how?
How long will it keep?

Re-using Yeast
New brewer (since 11/09). Brewing with extracts but thinking all-grain is in my future.

Yeast Life
That is up for debate. I have quite a few different yeast sitting in the refrig. I always make a yeast starter before pitching to make sure they are still active. With that said... I have used yeast six months old that has been sitting in a Mason jar under a inch or two of beer without an issue. Keeping everything clean is real important.
