I have been looking for this info on the site but can't seem to come across it and I am waiting on my copy of Designing Great Beers to arrive. I do not have the equipment to do an all grain, yet, but am going to do a PM doppelbock. I've been looking over recipes and had a few of you comment on one the other day. I keep changing the amount of grain it the recipe and figure the more gain I use, the better the beer will be and it will also cost less to make. If I have a 5 gallon SS pot, what is the most amount of grain I can use in a PM?
