Worlds away from the frosted pitchers of margaritas beloved by Yankees, Chantal Martineau begins the story of tequila in the agave fields of Jalisco. With the descriptive, put-the-reader-on-the-scene prose of an accomplished travel writer, Martineau follows the chain from farmers through distillers and consumers. She explores the rotgut most of us have tasted and the rise of refined tequila suitable for sipping—think 5 Star Scotch from the subtropics. Included is a critical guide to brands of tequila and mezcales.
