Soooooo, I may be overthinkimg it, or perhaps I'm not as sharp as I think I am, but what are you guys using to measure and pitch the yeast slurry in? Are you just using the flask that the starter gets made in, or perhaps I'm using some sort of big syringe? I'm stumped.

If I'm growing up from a vial, I trust to my calculations based on starter size, etc. If you are looking to pitch a slurry from a previous beer that has been rinsed, you can use any sort of glassware that has gradations on it... graduated cylinder, smaller flasks, etc..

I use a 500 ml beaker.
