While many hobbyists look for a for quick reference, the most "canonical" text in the industry is The Coffee Brewing Handbook by Ted Lingle, published by the Specialty Coffee Association (SCA). It is a technical deep dive into the "Brewing Control Chart," a tool used by professionals to map extraction yield against strength. Digital Alternatives for Home Brewers
