As an avid home brewer. an engineer, and committed technical researcher of beer chemistry and process I found it an interesting read. At the time period this was written there was little to no technical documentation available to the author. The observations with respect to basic malting and hop harvesting are pretty actionable and reasonable. The common lack of understanding about yeast, which in the era would have been near zero, proves malt, water and hops just want to be -- which explains the historical quote that God loves us for he gave us beer. That said, It is interesting and understandable that beer quality varied so widely from the process description provided. The read is extremely quick and must be the intent that you want to understand what the common practical knowledge of brewing was then, Thankfully so much research has been accomplished, published and shared so the common home brewer can make a high quality beer today.
