Overpitching is as wrong as underpitching (that is why it's not good to pour fresh wort on a whole slurry from previous beer - there's too much yeast in there)
I've been told about 1 cup of slurry per 5 gallon batch. Does that sound about right?
If I understand things correctly, that was Shawn Hargreaves's point of underpitching. The time it takes to produce enough yeast to fully ferment the wort. Too long in the exponential growth phase and you get undesired byproducts.I know enough microbiology to know that yeast go into an exponential growth phase at a certain point. So, it seems to me that as long as there is enough oxygen etc. that it shouldn't matter whether you start with one organism, or 1 billion. Assuming that the one survives of course.
The food the yeast need is a constant. The only difference between a lot of yeast and a little is how long it takes to consume that food.
the undesirable byproducts make sense to me. But, the FG at the end should always be the same no matter the size of the pitch......right?

that would be true if the yeast were old. But, they're babies. babies shouldn't be tired yet. They were just created.
