Hey i am only 19 and live at home. I am the only member of my family who likes ale and beer at all so have no need to brew 5 gallon batches. I have been looking into brewing simple 1 gallon batches of all grain beer. I understand all of the processes involved and have all the equipment necessary. However all recipes i find are for 5 gallons or more. Can i simply divide a 5 gallon recipe by 5 in order to make 1 gallon?
