From Booklist
Although Janson claims this course in chemistry for the nonchemist is for "the homebrewer whether beginner or expert," it likely will be of most help to the intermediate or advanced home-brewer eager to fine-tune and standardize output. Janson tries to keep the hard science to a minimum and explains terms and processes fully and clearly. Still, he charts a lot of molecular structures, but his explanations are so comprehensive and his perception of common home-brewing problems so canny that the technical material won't drive readers away. The chapter on avoiding "off" flavors alone is worth the price of the book, and the chapter on evaluating beer and the insightful glossary just make it better. So if you are concerned about flocculation and avoiding that "baby diaper" or "skunky" taste and aroma, make this required reading. Mike Tribby

Review
"...carefully written and easy to read. This is a book that even nontechnical brewers can read to advantage." -- George Fix, Ph.D., author of Principles of Brewing Science

From the Back Cover
Now every homebrewer can make better beer simply by knowing the basic science behind the components of beer and fermentation.

Do you need to have an advanced science degree to understand brewing chemistry? Certainly not! Any brewer, explains author Lee W. Janson, can understand the basic details of the life of a yeast or the careless steps that produce those annoying off-flavors -- and learn how to avoid them.

Brew Chem 101 features:
-- Nontechnical language and a highly readable style
-- Explanations of the chemical reactions at each stage of the brewing process and how to avoid potential problems
-- A primer on beer tasting and judging

A Brewing Chem Book for Non-Brewers?
I am an analytical chemist and homebrewer. I thought this book would be targeted towards an audience that was interested in both. Seriously, who else is going to buy it? In its attempt to be "non-technical," it simply doesn't cover the subject matter.

The worst thing is its complete failure to discuss water chemistry and pH control in the mash. There is a table of ions, but nothing more. Despite being a "chemistry book," it never even defines pH. Look up "pH" in the index and you get "pH, measuring." That's it.

The "best" chapter -- on off-flavors -- offers trite answers; lots of info on what to do, no guidance whatsoever on HOW TO DO IT.

The last chapter is on how to be a homebrew judge. Sorry Dr Janson, but that topic is UTTERLY IRRELEVANT to the subject of your book!!

I have been more disappointed in a book purchase, but not often. I anticipate having a difficult time even giving it away. Do not buy this book.

A good "basics" book
If you have a degree in chemistry, microbiology, or biology, this book is not for you. Buy George Fix's book or one of the texts by the Siebel Institute. This book is also not for the all-grain veteran looking for insight on the mysteries of recipe formulation and yeast interaction. Finally, Brew Chem 101 is certainly not for the professional brewer. This book is best for beginning - intermediate homebrewers looking to move from extract brewing to partial mash or all grain brewing.

I found this book to be an excellent introduction to brewing science for people long out of high school and/or not really science-types. It is fairly light on technology and terminology, while providing sound fundamentals on good brewing. As others have pointed out, the science in the book is not 100% accurate, but it is accurate enough for homebrewing and it seems the author intentionally simplified the science to save overly long explainations on obscure (read, boring) topics. I have some issues with the techniques used in the book, especially regarding boiling grains, but ask 50 award-winning brewers to define the perfect brewing technique and you'll get 50 different answers.

I do wish Janson had provided much more information on water chemistry and the effects of temperature at different stages of mashing, but I understand this book is meant as a springboard to further reading.

I appreciated Janson's chapter on off flavors. He provided easy to understand descriptions, possible sources, and ways to avoid them. While his solutions may seem obvious to advanced brewers, they are accurate the provide a fix to 90% of the problems encountered by novice brewers.

Everything in this book can be found on the Internet or through your local homebrew club, and there is no published "perfect" book on homebrewing. However, it is nice to have a reference book on the shelf and, for what it is, Beer Chem 101 is very good. In conjunction with Dave Miller's Homebrewing Guide or Charlie Papazian's The Complete Joy of Homebrewing, Janson's book provides an easy progression from extract brewing to all-grain brewing. I would have liked an advanced section on water, yeast, and mashing to ease the transition to Priciples of Brewing Science by George Fix, and I had a few issues with technique, so I have given it 4 stars.

This book is targeted towards advanced-beginner home brewers
Brew Chem 101 is an informative book that is targeted for the home-brewer who is just moving into mash-extract or all-grain brewing. The author keeps the explanations simple and gives definitions of the terms used. It's a good introduction to the chemistry of brewing for people who don't have a lot of chemistry background. I had thought it would get a little more in depth in explanation of chemical reactions, but after realizing who this is written for I would say it is a good start for someone wanting to learn the very basics. Advanced All-Grain brewers need not read this book though since it spends a lot of time explaining the proceedures and why they are done.
