Making something out of (next to) nothing

...in this case beer. After a big house move to a completely new neighborhood and a sizable whack to the credit card in the process, I currently don't have any money for beer (or purchase additional ingredients) but what I do have is a unique set of skills a few leftovers from previous beer making projects.

'Have you got any leftover grains by any chance?'

Can we make a brew that is true with this lot?
