I know where my mistakes are, and my best by the numbers batch was the one I kegged today, which was the first time I ever made it. By krausen/looks, the batch I made two days ago, once again, a completely new recipe, is probably the best batch so far. I'm going to double mill my grain, and I have all confidence that it will show better efficiency. The actual steps you take, don't change. A recipe is really only about grain, hops and timings, and efficiency. That's my opinion. I totally understand why people want to PERFECT a beer. I'm not that person. I'm looking to make easy to ferment IPAs with good taste. I live in Australia where a case of good, craft beer, is 130$ a case. So this is really about saving money for me, not a hobby. That being said, I'm falling in love with it!
