I am relatively new to this and had a quick question about water amounts. First, I have told myself I will brew 10 basic batches before I start deviating to much, as I want to get the process down before I start doing more advanced brewing. I have bought 4 basic kits that contain LME, specialty grains, hops, and the sugars. The directions state to basically use 2.5 gallons for wort and then to dump the 2.5 gallons of wort into 2.5 gallons of water already in my fermenter (after I cool the wort). Ok, simple enough and I have done so in all my batches so far....but my question is this..
I have a 40L brew pot, doesn't it make more sense to do the entire 5 gals at once? Do I have to boil, steep, and so on with only 2.5 gals? With such a big brew pot it doesn't take long to get a boil.
Am I missing something here...advice anyone?
