Cry Havoc wash I did yesterday. These are 1 quart jars. I will test attenuation on my next batch since there was no OG reading for this brew. Is the brown stuff dead yeast or trub?

The results of my first attempt at washing yeast. Harvested some wyeast 1056 from a batch of honey porter. The illustrated guide was very helpful. Keeping my fingers crossed for no infections and looking forward to using this in future brews!

Can't argue with fresh yeast.

very true, fresh yeast always yields the best result. but what's the percentage difference or perceivable difference between them is the question. I've used washed yeast that's 3+ months old and the difference is so negligible that it's not even funny. just brewed with 6 month old yeast right now and It's taken off like a monster and smells n tastes like a million bucks.

A lot of it has to do with the type of yeast too. From that Brew Strong episode they mentioned the Hefe yeast will start to give off flavors if it is not used within a couple of weeks. They did say other yeasts can last for several months after being washed/rinsed with no ill affects.

The part I don't get about this idea is age of the yeast after what? Harvest? So if you make a fresh starter it should reset the clock? White Labs and Wyeast make the yeast basically the same way we do.
