Been reading the book for a few days. Pretty interesting. Some of it is a little confusing, but I can figure it out. The only glaring thing I saw was in measurement conversion chart. It states that that 1 oz is 30 grams. It is actually 28.349 grams per oz. That should not make a big difference in smaller batches. But, if you scale it up, it could throw the hydration and other ingredients off by quite a bit. Other than that, it is a fun read. I do think what I have been taught on the forum, is better than what I have seen in most books.
