California wine expert, and author, Stephen Brook summarised Tina Caputo's monograph as follows:

* It is a compact guide and thoroughly up-to-date with entries on newly approved sub-regions such as Fountaingrove and Pine Mountain. * All the current AVAs are included. * It includes information about topography, varieties planted, and leading producers. * Packs a great deal into 70 small pages, with succinct sections on the major towns and their attractions, gastronomic and otherwise, and on Sonoma;'s very lively food scene. * Contains a single but handy map, but visitors to Sonoma can easily pick up regional maps in the tasting rooms. * Caputo unfailingly steers visitors in the right directions * Also available as an ebook via Amazon * (www.stephenbrook.com)
