From the reviews:

"This compilation is outstanding. Forty-nine contributors from eight countries offer recent information on the microbiology of wine production, covering specific topics in both breadth and depth. ... each of the book's 27 chapters stands alone, there is excellent continuity between chapters to give readers a good overview of the subject. ... The text contains detailed tabular information and clear, readily understood figures. ... This is excellent scientific reporting. Summing Up: Highly recommended. Lower-division undergraduates through professionals and practitioners." (G. S. Howell, Choice, Vol. 46 (11), 2009)
