Can I salvage this yeast-washing attempt?

I tried using a bucket and a brown-glass growler to do my washing before pouring the yeast into the mason jars. Since neither the bucket nor the growler really let me see what I was doing, I was more or less just pouring blind. It looks like I ended up with a thin layer of yeast and a whole lot of trub.

Is it possible to salvage this, or should I just toss it and wait until I get some clear glass vessels to use?

That's probably plenty of yeast to brew another decent gravity beer without even a starter. As long as you were clean in your process, save it and use it.

Edit: there's still lots of viable yeast in that "trub"

My understanding (and I may be wrong) is that I wouldn't want to pitch a bunch of trub into a new beer as it may introduce weird flavors. This came from a pale ale and I want to use it in an ESB.

I suppose I could try to decant just the yeast off into a starter, but I worry about transferring a lot of trub with it.

You can wash that yeast, very easy to do.

You are actually on step 1 now.

Just pour off most of that beer leaving the yeast and trub and then follow the rest of the video.

Correction: you were already trying to wash it. With what you have there, just pour off the beer, add boiled and cooled wash water to fill it back up, and then wait 20 minutes for the trub to settle out. Then pour the yeast into clean containers.

The containers that you pour into don't necessarily need to be clear, but that would be nice.

You could just put all that in the fridge and wait until you get some clear containers.

That makes sense. In fact, I feel pretty dumb for not thinking of it.

Thanks.

Not dumb at all. Happy washing!
