This is a superlative introduction to the world of sake from one of the great Western capacities on the topic.
A designated sake brewmaster (a so-called toji), apparently the only non-Japanese to enjoy this status, Mr Harper is an excellent guide to all those new to sake. Even if you know something about the tipple already, like me, this slight volume is packed with information.
The book covers the production, history and classification of sake, interspersed with translated reviews from one of Japan's premier sake connoisseurs, Haruo Matsuzaki. In addition to being written with much wit and humor, Mr Harper's inspiring writing had me want to meet with the author -- I'm certain he's excellent company and a fabulous live guide to this hallowed drink.
It's also a very beautiful book, excellently layouted, well-presented and visually appealing.
