I'm in the middle of washing my yeast and I was wondering if anyone could just give me a little information on what is in each of the layers in the picture. I was assuming that the bottom layer consists mostly of the trub and such, the middle and top layers would be mostly yeast. Am I correct for the most part?

Boy, it's hard to tell in that picture. How long as it been sitting? Usually, I pour off of the "heavy" stuff as soon as it starts to settle, and then do it again with fresh water. Your yeast layer (don't really see one in that picture) should be a thin layer of white creamy yeast.

I'll see if I can find a picture of very distinct layers to show you what I mean.

I can't find a good picture of the three distinct layers. But once you get rid of the heavy solids, and rewash, you should have something like this: (taken from homebrewer99's gallery)

What yeast was it?

I asked because layer 3 looks like the yeast clumps I had in two jugs. One had American Blend, the other was Edinburgh Ale.

Depends on the yeast....that looks like a really flocculant yeast such as WLP002/Wyeast 1968 to me, in which case the yeast is on the bottom.

I was looking around and I found a picture on this thread that looks a lot like mine. The picture on that thread shows wlp002 which is a very flocculant strain similar to wlp029, The bottom layer in the picture and in my jar look very similar so I'm assuming that as Buzzcraft said my yeast will be on the bottom

http://www.homebrewtalk.com/f163/yea...trains-152080/

If i break up each layer from the picture I posted I would say that layer 3 is the yeast, layer 2 is trub and dead yeast and layer 1 is beer. Does this seem correct?

Here's the what it looks like after I decanted off the top layers, added more water and let it sit for an hour.

Layer 3 is larger clumped trub
Layer 2 is small clumped trub
Layer 1 is suspended yeast. This is waht you want to pour off and keep. It contains the yeast you want to keep.

If you look closely you can see the yeast settling out between layers 2 and 1

Sorry to disagree but, I recently brewed one batch and split it into 4 jugs using different yeast. Two of the jugs have a layer like layer 3 and two did not. I would think that all four would have had that layer IF it was just trub.

BTW, all four had a layer like #2.

Not necessarily. If the two with layer three were the last two poured they would have more trub than the first two poured.


Yeast washing is definitely an art -- you need to learn when the timing is right to decant off the trub to keep maximum yeast. In that picture you can see a thin white layer at the top of level two just below the liquid in level one. That's yeast. He actually should have decanted that liquid a few minutes prior to taking that picture for maximum yeast. However, it's better to get no trub and lose a little yeast than keep some trub with the yeast.
