Why does one use the yeast nutrient for beer? Wouldn't the grain provide sufficient nutrition?

[Gil Breau]

Reduce time to flocculation?

Beats me, that'd be my only guess.

They're used as a "more complete dietary supplement"... stuff like vitamins, minerals, biotin, etc. Not sure if they make a huge difference, but a large supply is very cheap, so I throw in 1/2 tsp as some have recommended.

I don't think it has anything to do with flocculation. Just think of it as a yeast multi-vitamin.
