Size of starter

He's a nice guy Jamil - gave me permission to use his work when I wrote the pitching rate calculator in BeerAlchemy.

His newest calculator is very nice bit of work.

Do I just add all the liquid since there will still be yeast in suspension? Or do I pour off and just add the slurry at the bottom?

You can do either, I tend to find pitching the whole lot when its actively fermenting the starter gets the fastest start. For lager, you should definately only pitch the slurry to avoid picking up any of the potential off flavours from the starter.

Damn, just noticed something stuck to the inside of the bottle where my starter is. I have no idea where this has come from or what it is.

I assume it is too early to tell if I have contaminated the starter? Could I potentially ruin a beer with this? Fair enough I am making a stout so this is quite difficult to ruin but still....
