So I just order a couple extract kits from AHS. This will probably be a dumb question, but here it goes. It says on the directions to boil 2.5 gallons of water, but my question is can I just start out with 5 gallons of water since I have a large turkey fryer pot being heated by propane?? Also any suggestions on how to make their Bavarian Hef better beyond their directions? I have heard adding half of the extract at the last 15 minutes of boil time instead of all of it at the beginning? Thanks
