The power of a stir plate

I’ve put together a video showing the power of a yeast stir plate. The flask started with just a few milliliters of yeast and a liter of wort. Overnight it mutiplied to the giant amount you see in the video, which I estimate to be over 200 milliliters of pure yeast. It started off my fermentation within a few hours, and it was going very strong. The yeast is WLP007, Dry English Ale Yeast, and this is the fourth generation since buying the original vial.
