I give this book 10 out of 10 acorns - it's a textbook that wouldn't be out of place in either agriculture or anthropology curriculums.
A classic text on fermentation from an anthropological/permacultural perspective.
Written in Mollison's inimitable style with his razor sharp intellect and acerbic wit.
An excellent history of human food preservation with lessons, recipes, techniques from the ages.
Best of all, it is freely available in a number of formats on the open-source book repository archive.org
