"Kerin O'Keefe's book is the best thing I have read on Brunello di Montalcino--period. The research is the most thorough, and the coverage of the key aspects of the Montalcino situation--origins and history, legislation, zonal variations, producers--is the most complete and rigorous I have encountered anywhere."
