I want to do some experimenting with graff. My plan is to do a bunch of different 1 gallon batches (using different beer styles for the wort). Based on scaling the 5 gal recipe down to 1 gal, I would be mashing about 1 lb of grains in .2 gallons of water. Is this something that is possible to do? Is there anything I should do to differently with such a small mash? Is this stupid?
