The philosophy of Dave Arnold is simple: If you think like a scientist, you can make better drinks. Liquid Intelligence takes readers behind the bar and into the lab, where Arnold experiments with temperature, carbonation, sugar concentration, and acidity to find new ways to enhance classic cocktails – from bubble formation to the ideal sugar ratio for a Daiquiri. With innovative techniques such as clarifying cloudy liquids with gelatin and chilling drinks with liquid nitrogen, as well as practical tips for making flavored spirits and homemade bitters, Liquid Intelligence is aimed at anyone eager to learn the background and methods of a perfectly crafted drink.
