I've tried to rinse the trub/yeast cake in order to reuse S-04 yeast for a brew I am planning. However, I'm not sure whether I really caught any. I am trying to upload a picture of the jar I have. Been sitting in the fridge for 10 days. As you can see, there's a thick coarse greyish layer, and a basically clear, colored layer above (looks like a cloudy layer in between but that's just an image artifact. Does it look like it holds yeast, and if so, which part? Isn't it supposed to look more like the yeast cake, very fine and light grey? Of course I could just toss it into the wort, but I thought I'd ask the community first.
