Yeast Quantities

[durbo]

Hi all, I've just started creating my own recipes and loving it, I seem to have a firm grasp on all the ingredients except for yeast. How do I know how much yeast to use? Is it dependent on the expected OG? What will happen if I use too much or too little yeast?

Cheers

Short answer is off flavors. Possible if you over pitch, probable if you under pitch.

Beautiful. I knew there'd be a system, just a matter of finding it. Cheers heaps
