Book excerpt: Brewing with Cannabis introduces the convergence of marijuana and brewing in the modern craft beer movement. Explore the varied history of how the cannabis plant became federally illegal and dive into both historic and current laws on decriminalization and legalization of cannabis in the U.S. Learn about the agriculture and biology of cannabis, unique characteristics of the plant, and the similarities between cannabis and hop plants. Find out all that is needed to successfully grow cannabis plants in the comfort of your own home (where state legal). Examine the active components of cannabis and the chemistry of how they interact with beer. Discover how to de-carboxylate THC-A into the fully psychoactive form of THC and learn methods of adding cannabis and CBD to non-alcoholic beer and homebrew for different effects. Delve into how and why the plant produces compounds such as cannabinoids and terpenes, how they function, and how to incorporate them into beer recipes. Both homebrewers and professional brewers will be inspired by a wide-range of extract-based and all-grain recipes they can adopt or use as guidance when creating non-alcoholic beer or homebrew. Designed as a practical guide to use in brewing, the final chapter will inspire readers on how the discovery of new cannabinoids and terpenes may be used in the future. This book will be especially useful to brewers seeking information on the responsible and state legal of use of cannabis in brewing.
