Hey Guys,

I just signed up and have been reading for hours and hours and hours, I'm damn near crosseyed! I have a ridiculous amount of reading left to do. I find the more I read, the more questions I have and the more I need to read. Which is good, I'm really enjoying learning about it. I have 2 questions that I have searched for but been unable to find answers to and was hoping somebody could help me out.
-I'm finding a lot of recipes create a large mash. I was planning on using 6.5gal carboys for fermenters. This seems very common along with buckets and other various vessels around the same size. So the question is, is it ok to split up a mash into multiple fermenters and then combine the wash when ready to distill? ? From what I have read and deduced, I would say yes but I want to make sure I'm not getting confused?
-Is there a more technical/proper way of scaling down a recipe, for example just halving the recipe or are there other things that need to be considered?

Thanks in advance!
