Can dead yeast cells not function as nutrition?
Taking this a step further, would there be any downside to using a cocktail of different yeast slurries or could that introduce off flavours and competition between the yeasts?
Does this look OK, I only see 1 shade off slurryIf you let it settle for a day or so you will discover three layers.
The top will be a liquid. This is the beer and it will be sat on top of two layers of yeast.
The top layer of yeast is lighter in colour and normally thinner that the one at the bottom. These are the live yeast cells.
The bottom layer will be darker in colour. They are the dead yeast cells.
If you pour off the liquid and then take a sanitised spoon you can recover just the live yeast cells. These can be saved in a clean and sanitised jar, stored in the fridge (and save a lot of space) for up to six months and used either direct or to make a yeast starter for the next brew.
Hope this helps.
Don't worry about it.
I am on my second brew doing this, how many times can you use it
