I didn't realize the importance of aeration of giving nutrients until I read the book. The book doesn't make you a better brewer, but it does explain why you need to do things, like aerate the wort or must,.

I learned a lot from this book about the yeast life cycle and what it takes to make healthy yeast. I've applied this knowledge to my beer making and now aerate my wort and make starters, which I never used to do before.

The book explains why you should do things rather than just telling you to do something. This helps me out and makes the process more enjoyable and less rigid. After reading the book the next step for me is to get an Oxygen system.

I read a lot so much of this material was already known to me, but I still like having everything in one place. Its worth reading but there isn't that much thats directly applicable to home brewing.

It's a pretty good book and discusses some of the common knowledge in home brewing. The main take aways are it's important to aerate your wort before pitching, its very good to use a nutrient, don't ferment warm, and its very good to make a yeast starter. There is a lot on growing your own yeast that i wasn't interested in reading.
