Hi all. As I am moving from brewing other peoples tried and true recipes to experimenting with my own recipes, I find myself wondering if you can over pitch yeast. I know that you can under-pitch, and that can cause problems- particularly with lagers, but what about adding too much yeast? I ask because I have been making my test batches in 2 gal batches, that way if they are bad I only have 12-16 beers instead of 40 (16oz bottles) So, within reason, can you pitch too much yeast? If you do, what are the negative effects on the beer?
Thanks in advance
