Wow..... What that site don't got , you don't need!!! I spent the past day going cross-eyed on water table results and biocarbonate readings from every beer making city in the world. Combine that with he multiple rest points and hardcore equiptment suggested and it kinda makes brewing beer look more complicated than flying the space shuttle. I recon I'm more confused now than before....well maybe not but close.
To steal an analogy from The Matrix: That book will cerinley take you as deep inside the rabbits hole as you want to go!!!
