How many people keep log books and how detailed of information do you put into them. I jotted down notes from my first brew... but then I started thinking, It might be a great thing to start jotting down every bit of information... hops, extracts, weights, temps, yeast, ferment times, etc etc etc. Then at the end of it all, notes on taste and all. That way you will know how to recreate or how to stay away and eventually start learning from your mistakes!!! Just something I was thinking about! I have been cooking for many years and sometimes you make that one dish that was awesome...but then you can never seem to get it spot on and you just don't know how or what you did to get it there!
