"... brewers learned they could charge more for strong beer, considerably more than additional ingredients and labor would cost"I wonder if that isn't one of the reasons behind the extreme and other similar beers.
Actually, the quote above is incomplete, it starts with "As far back as the sixteenth century..." and was taken from Brew Like a Monk, a wonderful book by Stan Hieronymus, and it's only one of the many passages I could quote here.
Brew Like a Monk is a study of Trappist and Abbey beers and those they inspired in Belgium and the US. Is a book for audience with a more than basic knowledge of the brewing process, there is a lot of technical stuff (for example, there is a section that discusses the effect of the fermenter's geometry) and those who aren't familiar with it, at least in theory, will end up getting lost. Now, those of you who fulfill that "requirement" should not miss it!
The bulk of the contents are the stories behind some of the most famous beers from this family, on both sides of the Atlantic. It's a fascinating read. You end up understanding each of the beers in a more intimate and personal way. Though here I must admit that I wasn't so absorbed by the American part, but only because almost all of the beers mentioned there are unknown to me sensory-wise and I wasn't able to establish the same link I established with the Belgian ones. That aside, before reading this book I recommend you take note of the beers whose stories are told, get as many of them as possible and drink them as their stories appear on the pages. I did it with Orval and it was a wonderful experience.
There's no doubt that it is brewers, both home and small scale commercial ones, the ones who will get the most out of Brew Like a Monk (or BLAM, as Boak and Bailey have dubbed it). There are plenty of recipes and tips, followed by more recipes and tips that show that it's not always necessary to use a dozen different malts and half a ton of hops to make complex and interesting beers.
On a personal level, what I liked the most about Brew Like a Monk is that it made me think about and helped me understand quite a few things, while confirming a few others I've been saying for some time. How tenuous the concept of "Craft Beer" is, that saying that a beer/brewery isn't commercial is quite silly, the comprimises and trade-offs that success and growth almost inevitably bring, etc.
But above all, it confirms that passion isn't enough to make good beer consistently. It's also necessary to know the science of the process, the why and how happen the things that happen, and yet, at the same time, having the deepest knowledge of the science is not enough to make a truly Great Beer. You also need the right amount of art and spirit. You can call that passion, you can call that any way you want. I prefer to call it Alchemy.
